The introduction of low nitrogen emission boiler is the first time in a market-oriented approach using FGR technology products, as guardian of the "APEC blue" gave their part.

Third, pay attention to anti-corrosion treatment

In addition to the above two points is important to note, in daily use condensing boiler, you also need to pay particular attention to its anti-corrosion treatment. We all know how serious corrosion damage to the equipment, they will directly cause the surface coating off the boiler, not only affects the appearance, over time the surface will form boiler extensive damage, or worse still seriously affect the strength of the boiler.

Now we look together, when the hot water reasons for low steam pressure in boiler operations outage and restart the practices it!

1, the heating boiler is stopped, as is normal shutdown pressure fire, the blower should outage, then outage induced draft fan, the coal supply is stopped, but not circulating pump outage. Because the water pump outage may cause water vaporization furnace, water pumps still continue to operate. When the system temperature dropped to below 50-60 ℃, and then stop the circulating pump. The intermittent heating may not be necessarily shorter interval outage circulating pump.

2, when the furnace start again, should open the circulating pump, the water in the system has reached normal cycle, open the induced draft fan, blower, start the grate and the coal system, gradually recovered coal combustion. When the shutdown longer required pressure furnace, combustion should preferably seam, after clearing slag, then covered with a thick coal seam fire pressure.

Electric reasons for low steam pressure in boiler operations automatic shutdown of the reasons? 1, when the electric boiler system has a shortage of water, electric boiler will automatically shutdown. This can effectively prevent the occurrence of the phenomenon of dry, if the furnace food warmer water boiled away, there is no timely shutdown, it is easy to damage the boiler. 2, when the circulating pump fails, does not work properly, shutdown reason? Electric boiler will automatically shutdown. Water in the system will no longer continue to cycle, if there is a spare pump in the installation of the boiler, can be manually turned on spare pumps, electric boilers electric boiler automatically so you can continue to work during the overhaul, it also will not affect the normal operation of the system . 3, the heating furnace tube rupture or explosion occurs when the tube is like, electric boiler is not working, will promptly shutdown, power failure. To prevent the danger, the heating tube should be promptly replaced. 4, if the power electrical components of the boiler problems, electric boilers will alarm, automatic shutdown, if the line work, it is easy to endanger the lives and safety of staff.
