horizontal multistage hot water boiler residential

Fuel gas steam boiler cleaning methods and maintenance Comments? Necessity boiler steam boiler fuel gas washing operation over a long period, the inevitable emergence of scale, the problem of corrosion, boiler scale formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation in an oven within a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale. Maintenance 1 gas fuel steam boiler, gas steam boiler feed water must go through qualifying process, which is to extend the life of the boiler, ensure the safe operation of the important issues. 2, feed water temperature should be as close to the furnace temperature, preferably above 20 ℃. 3, the low water cutoff for periodic inspection and maintenance and cleaning apparatus. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. 4, requires periodic operation of sewage per day (per shift) at least once, you should check whether the sewage drain valve due to possible contamination and leaks; if it must be excluded. 5, when the steam pressure is not maintained while the shutdown, the steam boiler space air entrapment generates negative pressure, and therefore should rise again to the fire burning total steam valve is opened. 6, after the smoke tube fouling will lead to increased exhaust gas temperature, so that boiler efficiency is lowered, so that the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling.

Industrial boilers is a major driving force for social development, but also brought great pressure on the environment. Whether coal-fired boilers, biomass boilers, or, when the supply of energy, the emission of pollutants will soot and nitrogen oxides. Some enterprises in order to save costs, the pursuit of more profits, but also allowed to change the fuel, biomass boilers burning coal steal, wood, and even garbage doping or other industrial waste, produce dioxins and other carcinogens directly into the atmosphere after combustion, pushing PM2.5 concentrations.

Since started Blue Sky Battle horn Guangdong Province, many cities have begun to respond positively, Dongguan City, is one of them. Atmospheric do in-depth business thoroughly, and the development of industrial boilers business accounting, confirming the city's need to eliminate highly polluting boilers have 765 units, of which 728 sets of biomass boilers, 37 coal-fired boilers. Subsequently, promote the transformation of facilities operations out of high pollution boilers within the city.

As of May 14, 2019, the city's 324 enterprises active removal of 363 coal-fired boilers burning biomass, as well as 83 to 84 companies demolition of the old boiler pipes, 447 completed phase-out plan of the boiler in advance.

Although there are many companies take the initiative to carry the main responsibility for the ecological environment, but there are still some chances enterprise.

Atmospheric Office official admitted that "in the daily inspection, the company found that some still illegal use of boilers, perfunctory 'coal to gas' work." Among them, although some enterprises written off coal, biomass fired boilers, but because of natural gas boiler installation behind schedule, forced production needs, but to let the old boiler continues posts. There are companies more "capricious", install two-way pipeline for new and old boilers, strict supervision when using gas-fired, law enforcement officers continue to take a coal burning biomass. There are even companies deliberately delayed "from coal to gas," progress, choose to enable the original write-off of the boiler.

This year, the Office of Atmospheric inspection personnel to go to 244 companies in the field to check the boiler usage, found that 42 enterprises there is illegal use of boiler problems. Among them, there are 18 companies of illegal use of biomass boilers has been canceled. "Not only pollute the atmosphere, there are still significant safety risks." Atmospheric Office inspection personnel Lurui Quan said, "the city's coal-fired, burning biomass boilers as well as 113 units, involving 94 companies, is expected to complete phase-out year, access to clean energy. "simple behind the data, there is a thick ledger out of the transformation of the boiler," when removed, when write-off, out of a pin number one glance. "

Atmospheric Office official also said the recent city towns Street (Park) Atmospheric Office will carry out investigation and remediation special action has been canceled boiler, supervise and guide enterprises to demolish the old boilers and pipes, put an end to "note not sell" phenomenon. At the same time, urge enterprises will have been dismantled boiler dedicated to the sale of scrap recycling company, effective way to solve the old boiler, complete eradication of pollution and safety hazards.

How much pressure horizontal multistage hot water boiler residential pressure hot water boiler as long as the current is concentrated by heating in the hotel industry and the industry, because these two industries are currently need to use very large amounts of hot water, especially for the heating industry needs hot water is even greater. In this regard, as these two sectors, then the procurement of pressure hot water boiler, must be combined with the actual situation of each boiler plant of accounting, but also to go through a wide range of contrast. Recently, there is a fast boiler heating companies to consult, want to buy several pressure hot water boiler for district heating, but heating area just know their own data, but for the tonnage involved on the required number, the number of and the cost of procurement is not very understanding. Technical staff want help fast Boiler accounting after accounting, concluded that the need for heating heating companies with three 10-ton pressure hot water boiler. At present, the model is about 1.4 million. The cost of purchasing a total of about 4.2 million. Therefore, the heating company for how much pressure hot water boilers already have a detailed understanding.

The price of the conventional gas boiler described the price of the gas boiler condensing boiler thermal efficiency of the fuel gas exhaust temperature boiler is generally 160 ~ 250 ℃, can not be condensed into liquid water and release latent heat of vaporization, causing a lot of heat loss; condensing fuel gas boiler condensate recovery, the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and steam, the thermal efficiency of the fuel gas steam condensing boiler WNS up to 95%.
