How to convert power fire tube boiler power and tonnage of the boiler (or output) is the amount of heat generated by the boiler per hour. Power or hot water boiler million kcal / hr (ten thousand kcal / h) is represented by MW (1MW = 1000kW). Amount of power, also known as evaporation steam boiler, the water is turned into steam per hour: t / h (T / h) or kilograms / hour (kg / h). Of course, it can be represented by MW or kW. In China, the correspondence between evaporation and power is: 1T / h = 1000kg / h = 0.7MW = 720kW = 60 Wan kcal / h = 600Mcal / h. There are units of horsepower (Hp) and boiler horsepower (BHp). 1Hp = 0.745kw, 1BHp = 9.81kw Europe evaporation steam boilers often marked note are:? The amount of steam "at212" word, is the amount of evaporation that it refers to 212 degrees Fahrenheit to 212 degrees Fahrenheit water evaporation, which is 100 ℃ water vapor evaporation amount of 100 ℃. Such an amount equivalent to 1kg evaporation heat 540kcal, we call it "equivalent amount of evaporation", namely: 1T / h = 54 million kcal / h. Thereby also calculate the relationship between boiler horsepower "equivalent evaporation amount" is: 1BHp = 15.62kg / h. 1, the heat efficiency of the boiler evaporation boiler 1 t / (t / h) ≈60 × 104 kilocalories (kcal) / time (kcal / h) ≈0.7 megawatt (MW) ≈720K kilowatts (KW) 2, boiler evaporation boiler horsepower 1 t / (t / h) ≈71.1 boiler horsepower (BHP) 3, and the boiler pressure international units of measurement engineering units 1 MPa (Mpa) ≈10 kgf / cm 2 (kgf / cm2) 4 , Pa and 1 MPa megapascals (Mpa) = 106 kPa (PA) 1 Pa (pa) = 0.01mbar (mbar) ≈10-5 kgf / cm 2 (atm Engineering) (kgf / cm2) 1 Pa ( pa) ≈0.1 mm of water (mmH2O) 5, 1 kgf gravity force (kgf) = 9.81 Newtons (N) 6, 1 kcal calories (kcal) (kcal) = 4.187 kilojoules (KJ) 7, the body ( volume) 1 m3 volume (m3) = 1000 liter (L) 1 liter (L) = 1000 mL (mL)
"Henan 2018 campaign of air pollution control plan" recently introduced, to guide and encourage medium-sized coal-fired fire tube boilers eliminated. In the province's foundation 10 steam tons / hour and the coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, the basic elimination of provincial cities planning area 35 steam tons / hour and coal-fired boilers.
Financial awards complement the way:
1, the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;
2, the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;
3, the completion of the coal-fired boiler Chaigai before the end of October 2020 no longer give financial awards complement.
Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.
The advantages of small electric steam fire tube boiler heating What are? Small electric heating steam pressure steam boiler has a variety of specifications, power electric heating steam boiler can choose. Electric heating steam boiler to electricity for energy, no noise, no pollution, no excretion, is a green product. Small electric heating steam boiler by the electrical control, ease of installation and matching; large boiler (500 kg) of the furnace body and an electronic control means to prevent electrical control portion of the furnace to high temperatures, to ensure stable operation. Temperature achieved by the automatic control cabinet. Using only heat and electric heating control process, a thermal efficiency of 97%. Advanced computer boiler controller has reliable performance, high degree of automation, easy operation. The use of high-quality electrical components to ensure product life. When the boiler risk of leakage occurs, the controller automatically disconnected from the supply, to avoid electric shock. Automatic replenishment: When the water in the boiler is lower than the safety level, heating the heating tube is automatically stopped, to prevent damage caused because dry, water and lights LEDs. Typically, the ground should be well connected with the Earth. Steam overpressure protection: When the boiler steam pressure exceeds the set limit pressure relief valve start and release the steam to reduce the pressure. Overcurrent protection: When the boiler overload (high pressure), earth leakage circuit breaker is automatically disconnected. Power Protection: by means of advanced electronic circuit detects an overvoltage, undervoltage fault state, reliable power protection.
Maintenance of common gas fire tube boiler you buy boiler equipment, will pay attention to a lot of problems, the number of thermal efficiency, energy saving and environmental protection whether, if the boiler manufacturers have to install special equipment manufacturing license, etc., are all you need to pay attention to the selection of points. But at the same time, the boiler in the course of regular maintenance is also very important. Regular maintenance of the gas boiler, can effectively extend the life of the boiler, improve work efficiency boilers, low failure rate, is conducive to the normal safe operation of the boiler. After regular maintenance gas-fired boiler, life, energy efficiency and the failure rate of maintenance should be carried out regular maintenance of the boiler better (especially boiler has been running for more than one year) than those without. Conventional boiler maintenance methods are: pressure maintenance, maintenance wet, dry maintenance, maintenance inflated. A pressure maintenance using pressure maintenance shutdown time does not exceed one week. Before the system shutdown process terminates filled with water to make soft drinks, is to maintain the residual pressure 0.05 ~ 0.1MPa, boiler water is maintained at a temperature above 100 deg.] C, can effectively prevent air from entering the boiler. Second, wet wet maintenance shutdown maintenance time does not exceed one month. In the soda boiler water softener system cheerful note lye, leaving no vapor space. This is because a stable oxide film with an aqueous solution of a suitable alkalinity can be formed with the metal surface, thereby preventing corrosion. Third, using the dry method maintenance shutdown maintenance time is longer. This is done; pot of water put the net after shutdown, residual heat boiler using a drying furnace, timely removal of residual scale and pot residue was then placed on the tray containing a desiccant within the drum and grate, Finally, close all valves, manhole and hand hole door. Regular inspection and maintenance, and timely replacement of the desiccant failure. Fourth, inflated maintenance Inflatable maintenance shutdown can be used for long-term maintenance. After the boiler shutdown, do not turn on the water, the water level is maintained at the high water line, to take measures so that the boiler deoxidation, then the pot of water and isolated. After the ammonia gas or helium gas through the pressure after inflation is maintained at 0.2 ~ 0.3MPa, nitrogen combines with oxygen to generate nitrogen oxides, so that the oxygen can not be in contact with the steel plate; ammonia was dissolved in water such that the water is alkaline, can effectively prevent oxygen corrosion phenomenon.
