In recent years, as people's growing awareness of environmental protection, the State also intended to promulgate stringent emission standards for nitrogen oxides. This boiler companies made a mandatory requirement - how to effectively reduce nitrogen oxide content in the boiler flue gas. Therefore, a focus on emissions of nitrogen oxides environmental revolution is quietly boiler industry. But for domestic boilers companies this road is not good to go, because the difficulty of controlling nitrogen oxides and more demanding of the boiler, every 1 mg / cubic meter of emissions control will cause the boiler costs dramatically.

Hejian former boiler installer Gas steam boiler Gas steam plant, should fill out the "boiler installation started this book", and was carrying at least pot seized by the following material to the gas steam boiler unit territories do boiler formalities license to install, only by consent start: ① gas-steam device license copies boiler; ② gas steam boiler plant boiler installation started this book and installation construction plans; ③ gas steam boiler certificate material; ④ boiler room plane CAD drawings and boiler room planning material; ⑤ device companies to participate in construction practitioners certified personnel. Former gas steam boiler device, and the device should also have agreed to carry the "boiler installation started this book" to use the unit earthly quality inspection departments Gas steam boiler pressure test equipment unit signed "quality boiler installation undertaking" for the inspection unit Numerical gas steam boiler means of supervision and inspection requirements.

Why boiler operation will cause steam temperature change (1) the impact of the steam temperature of the boiler combustion. Furnace combustion conditions change, change directly affects the heating surface of each heat sink share. Administration as discharge changes burner stops, and the nature of the fuel quality, the size of excess air coefficient, and change with the wind mode of the center of the flame, are increased or decreased on the steam temperature has a great influence. Effect of steam temperature (2) of load change. Superheater, reheater thermal characteristics determines the size of the impact load to the steam temperature change, joint superheater currently widely used, the use of convection and radiant superheater two different thermodynamic characteristics, so that steam temperature by Effect of boiler load change is small, but still generally close convection properties, the boiler load increases as the steam temperature is reduced correspondingly raised, lowered. Impact on the steam temperature (3) steam pressure changes. The higher the vapor pressure corresponding saturation temperature higher; conversely, the lower. Thus, as a result of a disturbance of the steam pressure has a more substantial increase or decrease, the steam temperature will be correspondingly increased or decreased. (4) water temperature and desuperheating steam temperature influence on the amount of water. In drum boiler, the feed water temperature is lowered or raised, anti steam temperature can be raised or lowered. Size desuperheating water flow more directly influence the steam temperature drop, lift. (5) Effect of temperature on the high-pressure cylinder exhaust steam of the reheat steam temperature. Reheater and export steam temperature is as high pressure cylinder exhaust steam correspondingly increases the temperature of the lift, it decreased.
