The compression operation of biomass energy-saving boilers is generally divided into hot backup compression and accident maintenance compression. The compression time is generally about 4 hours. At the same time, in order to ensure the safety of biomass energy-saving boilers, you need to pay attention to the following biomass energy-saving boilers Pressure fire operation requirements:

1. If the biomass energy-saving boiler needs to resume operation, only need to turn on the suction and blower, adjust the opening of the smoke and air baffle and the sectional air chamber adjustment baffle, adjust the thickness of the coal seam and start the grate when the boiler is burning normally. You can resume operation.

2. When the thickened coal seam is about 1 mm away from the slag stopper, stop the rotation of the grate and the operation of the blower and the induced draft fan, turn off the regulating plate and flue baffle of the small section air supply to an appropriate amount, relying on natural ventilation to maintain The weak combustion of coal is used to discharge sewage and raise the water level of the biomass energy-saving boiler to the maximum allowable water level.

3. Reduce the load of the biomass energy-saving boiler, thicken the coal seam according to the length of the shutdown time, and its thickness generally does not exceed 200 mm, and appropriately speed up the grate.

4. The length of the compaction time depends on how fast the temperature of the static material layer decreases. The material layer is thicker and the temperature before compaction is higher. The heat loss of the static material layer after compaction is small, and the compaction time can be longer.

5. Only the temperature of the static material layer is not too low, it can be started easily. The burning bituminous coal is generally not lower than 700℃, and the anthracite burning is generally not lower than 800℃. The normal pressure fire can be maintained for 16-24 hours.

6. If you need to extend the time, you only need to start the fluidized bed once before the temperature of the static material layer is not lower than 700 ℃ or 800 ℃, and run for about 1 hour to raise the temperature of the material layer, and then press the fire.
