Eco-friendly coal fired double drums hot water boiler
Henan difference fast boiler steam boiler steam boiler is a steam boiler with ordinary steam production machinery and equipment, generally used gas, or coal gas as a fuel, there are an electric steam boiler. Henan fast boiler for the inspection of the steam boiler is a steam boiler gas, fuel oil, gas, and it is common conventional steam boiler with the following differences: "steam boiler supervision norms" and the forthcoming introduction in June next year the new pot rules " boiler safety technology to monitor the specifications "are clearly defined steam boiler needs to be regulated by the state. In other words, users looking to buy a steam boiler plant boiler installation and can not be used directly. Before installation To pot seized by the approval and registration required for installation, and the need for inspection on a regular basis, usually one year during the annual inspection. But there are some of the steam boiler does not require registration and annual inspection, the old rules and the new pan pot regulations stipulate a water capacity less than 30L steam boiler is not within the scope of the surveillance. Because the water capacity of 30L water capacity than at home with a water heater are also small, so there is no risk of explosion, we do not need supervision. Henan water capacity fast boiler steam boiler 26L, belongs steam boiler does not require supervision. Steam boiler explosion hazards generated is amazing. In many steam boiler explosion in the boiler room were razed to the ground, the annual explosion of a steam boiler will be the first to cause casualties and significant economic losses. Henan fast boiler steam boiler is to achieve the ultimate, the boiler body through the scientific design, water capacity is very low, only 26L, itself, there is no risk of explosion on security. The thermal efficiency of conventional steam boiler is only 80%, while the party Henan boiler thermal efficiency of fast gas steam boiler can reach more than 93%. Henan plus energy-saving system fast boiler control systems, the actual energy savings up to 30%, running down a year could save hundreds of thousands of operating costs. The Henan fast boiler steam boiler without boiler room, an area itself is small, you can put in the basement or roof, it can also be placed directly next to the device requires the use of steam. Saving the cost of laying pipe network construction costs and the boiler room, a significant reduction in the use of the initial investment.
Works 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.
How to provide boiler thermal efficiency thermal efficiency of the steam boiler has the following methods: low-pressure boiler at the factory has been designed considering the problem of thermal efficiency of the boiler, the flue gas from the device or change little aspects of energy-saving possibilities, it is best to start from the energy-saving operation (here talk recovered water vapor condensation method). The current design thermal efficiency of domestic low-pressure boiler is generally 70 to 90%, generally the actual operation of the thermal efficiency of about 60 to 80%, some even below 50%, a small low pressure industry as long as the operation, maintenance properly, can meet the design thermal efficiency of manufacturers. I think the management and operation should pay attention to the following points: First, the boiler flue gas temperature monitoring. Typically the maximum exhaust heat loss is loss, it is important to good control of exhaust gas temperature, exhaust gas temperature is generally low pressure coal-fired boiler of 150 ~ 180 ℃, fuel boiler exhaust gas temperature is 210 ~ 240 ℃, so when the boiler to find out why when the exhaust temperature is too high and promptly eliminated. Coal-fired boiler flue gas temperature is too high reasons are: high furnace pressure; shorting smoke; thick soot on the heat pipe; thick scale pot like. High temperature fuel exhaust reasons are: 1 air not adjusted oil, the oil is not completely burned in the chimney the secondary combustion occurs aft; 2 soot too, the need for timely cleaning; 3 shorting smoke; 4.... thick scale; Second, controlling blowdown rate. Without restricting the general rate of industrial sewage control in 5 to 10%, in the pot of water to ensure that qualified (mainly total alkalinity and pH value), the blowdown rate as low as possible, the sewage to adhere to the "ground row, row less, are ranked "the rules. Third, the maintenance of good furnace wall insulation. The heat loss is also a relatively large heat losses, now the manufacturers in the manufacturing and design has been well thought out, so we do not need to change, we just trying to be difficult to maintain. Outer surface temperature generally does not exceed 50 ℃, it will have to find out the reasons such as too high, and remove. Boiler insulation should always be kept dry, for coal, not a long positive run, or easy to damage the coal furnace wall and gate and so on. Fourth, adjust the ratio of fuel and air volume, complete combustion of the fuel as possible. Generally do not have a small amount of wind testing instruments, we can only go by experience adjustment. For oil, the normal combustion flame was yellow-white, non-glare, flame stability, no visible smoke chimney; For coal, the normal combustion flame pale, no visible smoke chimney, basic cinder burn coal particles as even as possible. Fifth, the need for a sound water treatment. Improve water treatment and water quality testing can maximize prevent fouling and correct guidance of the sewage, but it did not do a lot of small, companies usually do not pay attention.
