economic use of gas fired boiler plant

The 35 ton circulating fluidized bed economic use of fired boiler plant in tetile plant belongs to the low temperature combustion, thus Nox emission is far lower than the pulverized coal furnace, only about 200 PPM, and can realize direct desulfurization in burning, high desulfurization efficiency, economy and technology and equipment is simple, the initial investment and operation cost of desulfurization is far lower than the pulverized coal furnace and flue gas desulfurization (PC + FCD).The discharge of ash activity is good, easy to realize the comprehensive utilization, no secondary ash pollution.

35 ton circulating fluidized bed boiler’s fuel wide adaptability and high combustion efficiency, particularly suited to low calorific value of inferior coal. The large range of load adjusting, about 30% of the low load to full load.

Industrial economic use of fired boiler plants 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.

1, the safety valve should be mounted vertically in a high position in the pot business, set box.

2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve.

3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly.

4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm.

5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of ​​the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of ​​the passage should not step short tube to 1.25 times the area of ​​all the exhaust valve.

6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust.

7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.

8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve.

How much is the current mill electric steam economic use of fired boiler plants, steam boilers many textile mills used more gas as the main form is, however, still gas resources in some places is not very good, so you need to take power as a medium. Textile mills in the procurement of electric steam boilers is to go through the full contrast, in this case, I will choose to compare their own boiler plant products. Recently, there is a textile mill to be fast boiler consulting, want to buy steam boilers, currently determine the form of electricity, but still want to boiler manufacturers here to help account for the price, and fast boiler technician for the textile mill after a detailed understanding of the situation, out of accounting data show that the two mills with electric steam boiler 2t on it. Currently, the types of boilers in the fast side of the price of 180,000, and that the total purchase cost is around 36 million. So, how much money the textile business for electric steam boilers already have a detailed understanding.
