This temperature is set to a portion from coal-fired boiler combustion process will produce a certain amount of sulfur dioxide (SO2 abbreviation), while SO2 below 170 ℃ will bind moisture and flue gas to form sulfuric acid, the sulfuric acid will in the boiler tail heating surface caused by corrosion, thus reducing the life of the boiler, the conventional coal-fired boiler exhaust gas temperature is higher than 200 ℃. But the temperature is high, it represents an increase in fuel energy loss, is not conducive to our goal - saving energy.
Electric horizontal steam boiler types equipment required to do the work of one thousand preparations electric steam boilers electric steam boilers Products Products electric steam boiler in accordance with the original power to be able to convert electrical energy into heat energy of some kind of original. Water or an organic heat medium heat (HTF) The heat transfer portion of the boiler heating to the necessary number of (temperature, pressure) three, and outputs the rated working substance energy industrial equipment. Electric boiler can be divided into: KS-D electric water boilers, CLDR (CWDR) electric water boiler (boiler comprising electric heating bath and electric boilers), LDR (WDR) electric steam boiler. Steam boiler is equipped refers to triple the number of required production and quality of the steam boiler. quasi. Electric steam boiler Ready to do one thousand have to do preparatory work to do. The main contents are as follows: (1) Be sure to use security guards to master the working principle of the boiler, all kinds of parts of the notes, features, and ways and means. (2) Fuel checkpoint, cables and pipes, and a total electric burner, pump and boiler installation notes. (3) Establishment of the main steam valve is normally open and normally closed, and then turned off. (4) inspection gauge to ensure flexible water level drop of Health, location no problem. (5) set the proper pressure regulator valve regulating the combustion.
Union Focus Group on democratic management to enhance, 2018 in the weekly publication of the level of reward single award, with only mechanism in the process of division and promote all kinds of competition, in a difficult time helping employees aftermath of experience, the group promoting the union all the time our staff carry out positive changes in the basis of life.
How small and medium sized boiler to adjust the temperature? Usually SMIs boiler temperature adjustment means no reduction, or only to change the level of air volume decrease means from the center of the flame gas side to achieve the purpose of adjusting the steam temperature. If the hot water boiler steam temperature drops, increasing the air blowing amount, the amount of flue gas increases, steam temperature rises; or increasing the amount of induced air, so that the chamber negative pressure increases, the center position of the flame shifting superheated steam temperature will rise . However, the boiler will adversely affect the economy. Air volume increased, the flame center will increase the exhaust gas temperature rises, increasing the heat losses; air volume is increased or decreased directly affect the quality and stability of the combustion conditions, thus affecting the thermal efficiency of the boiler. If improper operation, may also cause a fire or even turn off the furnace off. Therefore, small and medium industrial boilers should be taken to avoid sudden changes in temperature regulating air volume, reduced the adverse effects of low degree. If the vapor pressure of running hot water boiler, steam temperature exceeds a predetermined allowable value, already belongs to the accidents and dangerous area, you must take urgent measures to weaken combustion intensity, adjust the boiler load, air exhaust, severe will stop boiler run.Free Chat
