Basics 1 bd boiler steam trap dealer price maintenance, gas-fired boiler during operation Note the following points: (1) does not allow pressurized combustion gas boiler or furnace smoke, easy to burn out because stoker hole cover. Not on the bottom of the water (2) Gas boiler ground surface to prevent moisture corrosion. 2, gas boiler run every 2-3 weeks, should be checked once. 3, gas boiler run every 3-6 months after the shutdown should conduct a comprehensive inspection. (1) on the inside and outside gas boiler inspection, such as pressure welds, corroded steel inside and outside part of the phenomenon, if found should be repaired in a serious flaw, if the defect is not serious next time also to be shutdown to repair, if found when there is suspicious, but does not affect safety, records should be made for future reference. (2) can be checked and the water boiler primer coating to prevent corrosion. 4, gas boilers and boiler base paint at least once a year. 5, maintenance of gas boiler normally unused methods: dry and wet two kinds, one month shutdown, care should be taken dry method, wet shutdown can be less than one month regimen. (1) Dry regimen: the boiler furnace shutdown to discharge water, the inside completely remove the dirt, rinse, drying in the furnace with Weihuo (be careful not to fire), and a diameter of 10-30 millimeters block quicklime installed sub-plate, placed in the drum, without contacting the metal with lime, quicklime weight, calculated to the drum 8 kilograms per cubic meter volume, and then all of the manhole, the pipe valve closed hand holes, each of three months, check again, such as lime ingredients like broken, i.e. the need to replace, should be re-run the boiler and the lime disk unloading. (2) Wet regimen: After Shutdown of the water discharge released, the internal completely remove the dirt, rinse, refill treated water to the full, the water was heated to 100 deg.] C oven, so that the water discharge gas outside of the furnace, then close all the valves, cold climates where moisture can not support the use of law, so as not to damage the boiler furnace water freezes.
Gas boiler is run prevent excessive wind load caused by a low flame, combustion automatic adjustment device should be installed on each boiler, intake air volume and gas supply gas boiler control linkage.
How to convert power bd boiler steam trap dealer price 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)
