30kg natural gas steam generator

Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil. Compared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas fired boilers, etc., electricity Heating boiler operation is the most expensive, gas-fired boiler needs to be opened with gas pipeline, then, if there is no natural gas pipeline, but also hope that the operation cost of the boiler is low, only the choice of fuel-fired boiler. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving. After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with coal-fired boiler with the same parameters and capacity, the thermal strength of furnace volume can be doubled. However, in order to reduce the heat load in the combustor zone, the water wall tube in this zone is avoided. Because of the overtemperature, the furnace volume is only reduced by about 1 / 3. Moreover, because the ash content in fuel oil is very little, it will not be slagging on the convection heating surface, so the flue gas temperature at the furnace outlet can be as high as 1300 ℃, and the pitch between tubes on the convection heating surface can be reduced to increase the flue gas flow rate, thus the heat transfer coefficient on the heating surface can be increased. Save heating area and steel. In order to prevent spontaneous combustion of carbon black oil scale on economizers and air preheaters, steam soot blowers should be added to these parts to keep the heating surfaces clean. At the same time, because the fuel oil does not form coke slag, the membrane water-cooled wall can be used to form a micro-positive pressure (500 x 1000 cow / ml). A boiler. It can save the draft fan, only the fan can exhaust the flue gas out of the furnace. If the whole shell of the boiler is made of thick steel plate, it can also be made into a positive pressure (0.3 ~ 0.6 MPA) boiler, which can make the whole structure of the boiler more compact, and is more used in the gas-steam combined cycle generator set.

"Supervisory inspection-free small steam boilers principles and characteristics as the country increasingly stringent security checks on special equipment, many users are in for acceptance steam boiler to worry about, then there a boiler does not require annual inspection and acceptance? The answer yes, this is a free boiler 30kg steam generator inspection, supervisory inspector now free to receive more and more small steam boiler users of all ages, so check the small steam boiler-free monitoring What are the principles and characteristics of it? then it is for everyone explain. first small steam boiler uses a very broad, such as industry, food processing, school canteens, washing rooms, hospital disinfection, hotels, district heating, etc., there is gas, fuel gas and electric, in which the gas steam generator at present our company in the domestic production alone this one, steam boilers do not build a separate boiler room, small size, light weight, easy to move, can be placed in the basement, roof, etc., the Boilermakers do not need to operate licensed fireman, replacing each year dealing with government departments, small steam generator inspection-free than conventional boiler safety, this boiler will not explode, A coil is composed of very fast combustion starts, whether gas, fuel oil or gas to ensure that the steam can be three minutes, the subject does not require inspection and monitoring overpressure, over temperature, burning, water and other multiple protection , super safe, non-explosive, can greatly reduce the burden on the user.

Industrial production is inseparable from boilers, emission control of atmospheric pollutants boiler air pollution control in Shanghai to expand and intensify the focus of the project. Currently, Shanghai Industrial boilers alternative clean energy has been completed, nitrogen oxides (NOx) emissions of major pollutants as a boiler, the boiler due mostly low shelf emission source of ambient air near the ground and ozone greater PM2.5 influence, therefore, this release the new standard, the boiler will be low-nitrogen transformation, improve Shanghai air quality, protect people's lives and health and other aspects demand a strong thrust of great significance. Throughout the country, Beijing, Tianjin and other places have started low-nitrogen transformation boilers for low-nitrogen transformation has a more mature technology reserves. Based on the above considerations, for the effective control of NOx emissions from boilers, to further deepen cooperative control of PM2.5 and ozone, according to the standard first, to further accelerate the transformation of governance principles, it is necessary once again to revise the standard boiler.

According to local environmental standards and revision procedures, the Municipal Environmental Protection Bureau held a meeting to hear the relevant departments, enterprises and the opinions and suggestions of experts, and in 2017 August 4 to September 15 in the online open standard full text to solicit public opinion. At the same time the Ministry of Ecology Environment solicit written opinions Municipal Development, City Commission by letter and other related commissioned Bureau, industry organizations and boilers, production units and other enterprises. Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision on January 19, 2018 organized the expert technical review meeting, the panel agreed that standards through technical review. Approval by the Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision audit report to the municipal government.

The new standard has been revised for several aspects, one is no longer on the "central heating boiler and the nominal amount of evaporation less than 65t / h boiler cogeneration" provisions alone time; the second is to simplify the original class standard boiler merged into " gaseous fuel boiler "and" boilers "categories; are three different degrees of contamination tightened limits particulate matter, sulfur dioxide and nitrogen oxides; four new boiler is implemented from the date of implementation of this standard, the boiler given a transition period of about two years.

New standards for gaseous fuel boiler particulate matter, sulfur dioxide and nitrogen oxides are applied strict limits, but mainly considering the control of nitrogen oxide emissions, and further improve air quality. In the transition period boiler (1 October 2020) to limit nitrogen oxide 150mg / m³; after a transitional period of 50mg / m³. Date of implementation of new boiler nitrogen oxides from standard starting execution 50mg / m³ limit. Taking into account the comprehensive utilization of straw in Shanghai, biomass fuel boilers follows the standards of the original project control and limit requirements.

Throat automatic electric supply system of the 30kg steam generator, steam drying steady flow supplied to the user. When the water into the tank, the power switch, controlled by the drive signal, high temperature solenoid valve is opened, the pump work, is injected through the check valve furnace. When the solenoid valve, the check valve is clogged or damaged, the water pressure reaches a certain overpressure valve through overflow back into the tank, to protect the pump. When the tank without water or residual air in the pump piping, air not only into the water, as long as the rapid exhaust through the exhaust valve until the discharge water, close the exhaust valve, the pump will function. The main water supply system component is the pump, they use a multi-stage vortex pump of higher pressure and a larger flow rate, using a small part of the diaphragm pump or a vane pump. Stainless steel mechanical float level controller for generator furnace large volume, the working pressure is not stable, but easy to washable, maintenance and repair. Furnace boiler body generally use special seamless steel pipe, elongated upright. Most electric heating system or a heating tube used in a root canal curvature combination of stainless steel heating, while the surface load is generally about 20 W / cm. Due to the higher pressure and temperature when the generator is working properly, the safety protection system in the long run can make it safe, reliable and efficient. It is generally produced using high strength copper alloy valve, check valve, an exhaust valve, implement three protection. Some products also increased the water level in the glass tube protection device, increasing the user's sense of security. Product choice points: Electric steam boiler main control parameter is selected nominal evaporation, thermal efficiency of the boiler design, the rated steam pressure, the rated input electric power and the like. Use of electric steam boilers should meet the requirements of national and local restrictions related standards, norms. Using the selection of appropriate thermal storage electric boiler system, i.e., when the low electric power, the heat stored in the heat storage medium; at peak power stage, the heat stored in the heat storage medium released for users. It features electric boiler thermal storage system is different for peak electricity prices, operating cost savings for the user, and by peak load shifting power grid, good for grid security, economic operation. Electric steam boiler with the steam accumulator reservoir may be higher, the higher the heat of the argument, but the high electric steam boiler plus steam accumulator system cost, operation and management require a higher level, and therefore, do not ask for the heating parameters heating, living, air conditioning system, electric steam boiler plus steam accumulator system is rarely used. Electric power distribution chamber should be supplied directly to the boiler, the discharge conveyor can be used, or a metal cable. Determining the load and the number of electric boiler, boiler room should be combined transformer capacity equipped with comprehensive consideration. Many boilers can share a transformer, but not multiple transformers to supply a common boiler. Taipower power single steam boiler should not be greater than 2.4MW. Steam boiler feed water pot outside the general chemical water treatment, water quality should be specified. Installation and construction, installation points, boilers and auxiliary equipment, water treatment equipment should meet the technical requirements of the device manufacturer. Equipment foundation must be the arrival of equipment and after verification and design drawings before construction. The highest point of the pipeline deflation, the lowest point turn on the water. Acceptance pressure test after the pipe installation. Electric boiler room should all be grounded electrical equipment and heat storing devices. Precautions: power supply voltage can not exceed ± 5% of the rated voltage. Choice of fuel kerosene, diesel oil, do not use gasoline and heavy oil; when winter temperatures below 0 degrees, 0 # diesel oil are often solidification phenomena, not to use, it is best to use -10 # diesel or kerosene. You must be ground wire construction requirements:! Strength of electrical wiring must be separated, such as walking level sensors, pressure sensors and other electrical control of strong and weak lines output lines of the controller separately. When the installation site, should not wear in the same PVC pipe as arranged in parallel should be held at least 200mm intervals. Ban placed around the boiler gasoline, bananas, water and other inflammable and explosive materials. When using a gas boiler-room electronic leak detection alarm device should be installed to prevent accidents.
