Warm preheater, economizer, low-temperature pre-heater are connected with chimney, and maleic anhydride waste gas inputs the pipe outside low-temperature pre-heater and high-temperature preheater
Road is further separated into burner and Burning Room after being heated it, and the maleic anhydride waste gas in burner is mixed with natural gas and air
After-flame afterwards, the flue gas that indoor maleic anhydride waste gas is generated through high-temperature process that burns pass through the first convection bank, high temperature superheater, second
It is discharged after convection bank, low temperature superheater, high-temperature preheater, economizer, low-temperature pre-heater cooling from chimney.
Further, it burner and is burnt with the PLC programmable controller being connect with each hygrosensor and valve to leading to
The intake of the exhaust gas inlet and blower of burning room is controlled and is adjusted.
Further, the heating temperature range of burner is 1200 DEG C -1300 DEG C.
Further, after 254 DEG C of saturated vapors being passed through the pipeline outside the low temperature superheater and high temperature superheater successively,
420 DEG C of superheated steams can be exported
Further, boiler system is 35t per hour to the processing capacity of maleic anhydride waste gas.
The utility model has the advantages that
1) the utility model is by enabling boiler system in list for exhaust gas pre-burning, burning, the integrated design of abundant after-flame
More maleic anhydride waste gas are handled in the time of position, it is ensured that its after-flame.
2) it is controlled and is adjusted using the exhaust gas of PLC programmable controller pair and air inlet, it is ensured that boiler is stablized
Burning.
3) a certain amount of superheated steam is generated using burner exhaust heat, using by oneself, it is suitable to sell two.
