screw pipe 3 pass furnace coal fired steam boiler

To further reduce emissions of air pollutants and improve air quality of the environment, the Shanghai Municipal People's Government Office issued the "Opinions on accelerating the transformation of the city mentioned standard boilers of small and medium" (hereinafter "Opinion"), to accelerate the introduction of Shanghai City small boilers mentioned standard transformation respond positively.

Before the end of 2018, the district in conjunction with boilers and industrial distribution block, complete the development and revision of the Gas Pipeline Network Planning in this area. City, district authorities, according to the unit Gas Pipeline Network Planning and excavation plan, speed up the construction of natural gas pipeline network.

Variety of boiler fuel to replace natural gas, natural gas pipeline network (municipal pipe network to users outside the red line pipe) 50% of the cost of laying borne by the gas company; the remaining 50% by the district government and users each pay half, and encourage qualified district to provide more support. On the outskirts of the gas pipeline construction is temporarily unable to reach enterprises in the region, while ensuring security compliance cases, it can be in the form of non-natural gas pipeline, and implement an orderly transition after the completion of the pipe network. Encourage alternative gas supply business enterprises to provide gas price discount for the gas boiler.

10KV for the implementation of alternative electric boiler, 35KV and other business expansion project, to which the power supply capacity of the electrical part of the boiler, according to the city's non-resident business expansion project quota standards, engineering fees charged by half.

Environment departments to strengthen law enforcement and inspection of boiler units, fuel use, operation and maintenance, equipment maintenance, inspection, non-functioning facility once found, according to the law severely punished; at the same time, strengthen supervision and monitoring, if it is found excessive emissions, according to law strict punishment.

Boiler units and boiler mentioned standard transformation service units bear the main responsibility for the boiler safety issues involved. Site construction unit must have the appropriate boiler manufacture or installation (reconstruction) qualification, boiler commissioning personnel must have the appropriate special equipment operator certificate. Prior to the construction site mentioned standard boiler units to implement the transformation, boiler location should be informed in writing of special equipment regulatory authorities.

The district government is the responsibility of the main boiler to mention the transformation of the standard, according to the "ground principles" to promote the transformation of the boiler. Combined with the actual circumstances of the district reform implementation plan, accelerating the construction of facilities to ensure timely completion of the task of transformation, to ensure that policies and financial support in place.

Look industrial boilers requires selecting several points is divided into two uses, one is used to generate electricity, steam used for another. For now, most industrial boilers still dominated by coal, gas supplement. Moment in our country, the industrial boiler market has become saturated, so in such a market environment, we in the selection of industrial boiler when buying a few key points which should be valued? First, look quite different boiler manufacturers normality industrial boilers and boiler is that it is common for industrial use, and in general for small boilers boiling water bath completely different. Industrial use requires it had to have enough quality assurance, to meet its industrial needs. So when we choose to buy, be sure to choose a large regular and trustworthy industrial boiler manufacturers to make a purchase. Second, the degree of user information Positive feedback see the boiler user feedback information and sometimes are the ones closer to the product itself. And there is a good quality product in terms of user feedback must have a high degree of praise. So praise of the industrial boiler users are heavy when we select a reference value. When we make a purchase, you can advance praise from a number of channels seized of its own, in order to get buy high-quality industrial boilers. Third, look at the safety of the boiler furnace industrial boilers is enough as a large industrial equipment used in the industry often use to, then for safety performance should be extra attention to, to be able to reduce unnecessary dangerous situations. So this requires us to buy industrial boilers, this element should put safety first re-position, but also our first point to be valued. The above is the purchase should we value industrial boilers three points, of course, this is only part of it, not one where we were voiced. Then, when we want to buy industrial boilers, be sure to reserve well in advance of work-related knowledge, at the same time, a large selection of formal industrial boiler manufacturer to make a purchase.

Advancing the ignition point of coal, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal. 2. The air supply and reasonable regulation. In Grate, vibration stove, oven and forth, depending on the characteristics of the combustion process, reasonable air, to promote combustion furnace is very important. As the chain furnace, with grate the fuel is kept in motion, occur sequentially ignition, combustion, burn various stages. Along the longitudinal direction of the combustion grate stages, the partition, the amount of air required in the grate longitudinal direction is different. In the preheating zone of the head and the tail of burnout grate stage, small air requirement in the middle stage of combustion grate, the air amount required.

Works screw pipe 3 pass furnace coal fired steam boiler because the steam boilers and conventional boilers are not the same, because it does not require annual inspection, so there are a lot of users recently asked my principles steam boiler, steam boiler is how it works, I will give you an analysis by the steam today working principles of steam boilers in steam systems, water heating in the heater to a predetermined temperature, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the downcomer inlet waterwall header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam flows to the steam drum by the upper superheater, continues to be endothermic superheated steam of 450 deg.] C, and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere. That's all steam boiler works with you about today, the company's steam boiler 0.5 tons 0.5 tons horizontal and vertical steam boiler fuel gas-free acceptance, there is a need to contact us.
