Natural gas boiler after a period of time will have scale, rust and other problems, which requires us to clean up equipment from time to time. Natural gas boiler cleaning is not like our daily necessities cleaning, see how this article is introduced. After a long period of operation, the natural gas boiler inevitably has the problem of scale and corrosion. The main reason for the formation of the scale in the boiler is that there is a hardness component in the feed water, and after continuous evaporation and concentration at high temperature and high pressure, A series of physical and chemical reactions take place in the furnace, resulting in the formation of a hard, dense scale on the heated surface, resulting in a decrease in the heat transfer effect and corrosion factors under the scale, which will lead to a pot The water wall furnace heat absorption decreases, the boiler outlet temperature increases, and the boiler loss increases. At the same time, after scaling in the water wall, the heat transfer effect is reduced, which may lead to the increase of the wall temperature of the water wall and the explosion of the water wall, which affects the safe operation of the natural gas boiler. Scale is the most harmful factor of boiler, it is the main cause of boiler accident, and its harmfulness is mainly manifested in the waste of a large amount of fuel: because the thermal conductivity of scale is only a fraction of that of steel and the thermal conductivity of scale is only one-tenth of that of steel. Therefore, the heat transfer will be blocked after scaling on the heating surface. In order to maintain a certain output of the boiler, it is necessary to raise the temperature on the side of the fire so as to make it radiate outward. And exhaust smoke caused heat loss. High efficiency and environmentally friendly non-corrosive cleaning agent can be used to clean gas-fired boiler. The cleaning agent can completely dissolve the cleaning scale and make the tube of the equipment show the original metal color and reduce the influence of scaling and biological algal sludge. At the same time, it can peel off iron oxide and ferrous oxide, prolong the service life of gas-fired boiler, reduce energy consumption and increase productivity. Natural gas boiler cleaning should be carried out by professional cleaning companies to ensure a thorough and effective cleaning equipment.
With the community growing environmental requirements of the State Environmental Protection agency has for boiler combustion involving contaminated specific requirements, while the new low nitrogen gas boiler with low nitrogen treatment technology of energy saving, reducing the overall fundamentally combustion emissions, to meet our requirements for pollutant emissions standards. Gets National Accreditation boiler to produce low nitrogen can really provide protection for the production and operation of enterprises, in order to realize the implementation of environmental protection and production integration.
Henan gas boiler Henan basic components and working principle of gas boiler is constituted by a series of devices can be divided into two main parts and auxiliary equipment. Henan gas boiler main components are: 1. Furnace: Henan ensure the fuel and burn the gas boiler outlet gas temperature to a value of convection heating surface cooled safe work; 2, the drum: the respective gas boiler heating surface coupled Henan and together and water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 3, water wall: mainly radiation heating surface Henan gas boiler absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 4, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion; 5, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reduced exhaust smoke temperature, increase boiler efficiency Henan gas. 6, the furnace wall: Henan protective housing is gas-fired boiler, and heat from the sealing effect. Heavy furnace wall Henan small gas boiler can also function as a support member boiler. 8, the frame: a support member and a fixed gas boiler Henan
Recently, Binzhou City, Shandong Province High-tech District Supervisor Bureau to carry out special rectification actions boilers within the region, mainly to effectively prevent and resolutely curb special equipment accidents from happening again, strengthen security principal responsibility.
Inspectors use of "without warning, went straight to the scene" way of checking for nine boiler units within the region conducted a comprehensive inspection, focusing on aspects of boiler operation, the operator of personal responsibility, troubleshooting, safety test accessories, etc. a comprehensive investigation. Long-term idle boiler, supervise the use of units in time for deactivation procedures; management is not in place, there are security risks of the use of units, ordered deadline to complete the hidden rectification. The campaigns, check out a total of more than 30 people, to identify risks at 8, at the completion of the rectification 8.
Next, Binzhou City High-tech Zone Market Authority will continue to strengthen law enforcement and inspection efforts, compacted layers of responsibility, and strengthen security consciousness, special equipment to protect the region's security situation continues to stabilize, escort for the economic development of high-tech zones.
