The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

When a shutdown occurs while operating in the Manual position at other than low fire the damper will not be in a closed position thus allowing more air than desired to flow through the boiler Excess airflow subjects the pressure vessel metal and refractory to undesirable conditions
· Stop the cycle Close the steam stop valves Close the feed water valves When the pressure is just reduced to over atmospheric pressure the vent valve is kept open to prevent vacuum formation inside the
· The normal procedure for any is to and raise the alarm; in event of flame failure It is a trip that helps prevent the accumulation of fuel into the furnace chamber Thus it helps avoid the source of potential explosion when the is fired again
feed water is kept clean and the is inspected periodically to avoid internal corrosion or fouling which could destroy the Guidelines for safe design control maintenance and operator training are provided by NFPA 85 " and Combustion Systems Hazards Code" For a complete copy of NFPA 85 see
