wns 6 tons low nitrogen steam boiler
Henan gas boiler shutdown: 1. Press Henan gas boilers electronic control box "shutdown" button. 2, Henan gas boiler burner servomotor return to the initial position, the throttle valve is fully closed and gas. 3, Henan gas boiler solenoid regulating valve and the gas valve closed, the blower is stopped. 4, after determining the water temperature is below 50 ℃, stop the circulating pump. 5, the manual closing Henan gas boiler gas valve. 6, close the water supply valve and return valve. 7, check the gas lines, water lines, valves for leaks, air leaks. 8, the control system power down switch (air switch). 9, when the long-term disabled Henan gas boilers, boiler cut off the power supply. Learn Henan gas boiler Details: www.gu Panzhihua City, 10 tons of steam coal-fired boilers and complete phase-out is completed
The design of the power station needs the participation of the design institute with the qualification of electric power design. The principle is firstly put forward by the owner, and then the design institute selects the steam turbine according to the owner's requirements and selects the boiler according to the intake parameters of the steam turbine with considering the loss of pipelines.
As a leader in the fast side condensing gas boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback
Check items Notes wns 6 tons low nitrogen steam boiler and a steam boiler inspection Annex 1, the steam boiler pressure gauges, they check whether the abnormal water table, bend, and the intermediate connecting pipe mounting valve opening and closing without exception. The table below shows the water level is correct, whether the water table column drain valve correctly state, pressure gauge whether there is a statutory inspection mark within the time limit. 2, steam boiler safety valve, drain valve, vent pipe to check whether they have been adjusted to a predetermined opening pressure, vent pipe installation is reasonable. Check the vent pipe is blocked, whether the anti-Chen measures. 3, the opening and closing of the drain valve discharge inspection device is flexible, the gland liner whether to allow sufficient room for adjustment. Outfall road if there is an abnormality. 4, the main valve, the water supply shut-off valve and non-return check tie their open and closed states without exception, if the valve cover material left margin. 5, the air valve in the hydrostatic test water to full state, the start point of the furnace to appear vapor must be kept open state. 6, connection pipe inspection gas and water pipes, the support, the telescopic joint, and whether the hydrophobic insulation and meet the requirements. After scaling will overheat the metal, the metal will stretch creep, modifications, bulge, serious overheating of the tube when the storm. Scale layer is a heat medium and the metal wall; between the water vapor, since the scale layer is small thermal conductivity, a significant insulating effect, greatly increasing the temperature of the metal wall fouling. It is estimated that the evaporation heating surface, furnace deposited scale often overheated collapse, deposition of scale by the pot shell (drum) regular hot drum kit, the heating surface tubes deposition of scale is often overheat storm tube larger fuel amount of waste. Daily work to do steam boiler inspection matters, in order to ensure normal production.
