Pre-mixed condensing wall-hung boiler gas Z28BL1

We learned from Anshan City Bureau of the ecological environment: to improve air quality living environment for urban residents, according to government requirements, Anshan external publicity of the built-up areas and industrial parks and a list of more than 10 tons of coal-fired pre-mixed condensing wall-hung boiler z28bl1s, municipal environmental protection department also welcome all citizens supervision, to provide the city's built-up areas and 10 tons and above boiler clues industrial park outside the list.

Battle to lay the blue sky, the city has in recent years embarked on a built-up area and the city's industrial park and 10 tons of coal-fired boilers out of work, the city built-up areas and industrial parks and 10 tons of coal-fired boilers demolition of all the reservation coal-fired boilers to achieve discharge standards. As requested, before the end of 2020 in the city of Anshan City will be built-up areas and industrial parks all phase-out over 10-20 tons coal-fired boilers, coal-fired boiler units involved should be prepared in advance.

To further enhance the quality of atmospheric environment, promote environmental management to raise the overall level, in accordance with the requirements of the provincial government, the city of the city within built-up areas and industrial parks and more than 10 tons of coal-fired boilers information for publicity. These publicity boiler will be included in the list of key sewage units, strict supervision, to ensure the discharge standards.

Chemical heating 7,000 square meters of chemical plants need much heating pre-mixed condensing wall-hung boiler z28bl1 7,000 square meters of much needed boiler? Chemical heating typically use clean fuel, it is, after all, a high staff-intensive chemical plants not only to meet the requirements of national environmental protection standards, and comply with environmental requirements of the local city, generally use gas-fired boilers, biomass boilers, electric boilers, etc., and chemical plants need to use 7000 square meters of heating boilers, according to the local temperature in the winter, usually 1 t 2 t meet the demand. When it comes to gas boilers, our first thought is of high efficiency, energy saving and environmental protection. This is the advantage of gas-fired boiler, gas boiler is so popular. Since high efficiency gas boiler is so popular, users are bound to want to use a lot, but many users are more concerned with quote efficiency gas boilers, is not so popular. In fact, the price is slightly higher than the efficiency of conventional gas boiler boiler, but in the long run, save the daily cost is very practical. High efficiency gas boiler is not only efficient, in addition, automation and efficient operation of the gas boiler, not only security and stability, but also can save a lot of labor costs, at the same time, integrated design, less cumbersome, easy to maintain, you can also save a lot of maintenance costs.

The wns oil and gas pre-mixed condensing wall-hung boiler z28bl1 fuel we designed generally uses natural gas, light oil, heavy oil, coke oven gas, biogas, and the like. As such, it is convenient when using fuel, and the fuel can be delivered by piping. This boiler uses a fully automatic low nitrogen burner and flue gas recirculation system (FGR) system to achieve ultra low nitrogen emissions.

Three kinds of ventilation pre-mixed condensing wall-hung boiler z28bl1s often used at runtime to be continuously supplied to the boiler the combustion air required, and the resulting flue gas continuously drawn, a process called draft process of the boiler. Once the venting is stopped, the boiler will stop running; usually mechanically ventilated, i.e., by means of a pressure head generated by the fan to overcome smoke flow resistance of the duct. Mechanical ventilation currently used in the following three. A negative pressure ventilation chimney addition to using, the former also mounted chimney draft fan to overcome the resistance of all of the smoke, the air duct. This small capacity of ventilation, smoke wind resistance is not so large boiler system is more applicable. Second, while a balanced draft and induced draft fan blower mounted in the boiler smoke, air system. Port to the suction passage into the furnace from the wind (including through an air preheater, and a fuel combustion device layer) overcome the resistance of the entire duct fan; furnace outlet to the outlet stack (including a negative pressure outlet furnace, boiler slag tube after anti heating surface portions of the device and the dust removal) all by flue draft fan to overcome the resistance. This ventilation can effectively into the air, and the furnace flue boilers and all run under negative pressure, boiler room of the safety and health conditions better. If compared with negative pressure ventilation, boiler air leakage is small. Currently in heating boilers, the most balanced ventilation. Third, the only positive draft blower mounted in the boiler smoke in the air system, with its head against the resistance of all the smoke duct. Then the furnace and flue boiler are all working under pressure, and thus the furnace wall and door units are required tightly sealed to prevent leakage of flames and smoke high temperature hurt. This ventilation improves the strength of the heat of combustion furnace, boiler smaller volume equivalent capacity. By eliminating air leakage boiler furnace, flues, and improve the thermal efficiency of the boiler. Positive pressure ventilation, currently has applications in the oil and gas boilers. Boiler draft ventilation is generally balanced and positive pressure ventilation. These are the three common boiler ventilation method, in the process, to constantly add fuel, while also promptly clean up the burned ashes.
