The heat source of waste heat boiler is sometimes unstable, so pay attention to the fluctuation of water level and pressure. The composition of heat source of waste heat boiler shall be determined whether it contains corrosive gas. Pay attention to whether it will cause corrosion. If it does, the pressure shall be controlled higher than dew point corrosion. The waste heat flue gas contains smoke and dust, so the rapping device or purging device shall be started during the boiler operation. Strengthen the contact with the furnace providing heat source, timely deal with the problems found, do a good job in patrol inspection, and do a good job in pressure ratio and safety valve calibration at ordinary times. Waste heat boiler is a device that uses waste gas generated by heating furnace, boiler, coke oven, etc. to realize waste heat recovery and reuse of waste gas. Its key equipment includes heat exchanger for waste gas heat recovery, also known as waste heat boiler body, steam drum, deaerator , feed pump, circulating pump (if not required for natural circulation), and connected pipelines and auxiliary equipment. Its thermal principle is the principle of heat exchanger.
Henan Waste heat boiler manufacturer Observe the water level with a water gauge, and timely repair the damaged water gauge; Timely replace the pressure gauge if it is damaged or the dial is unclear; The valve that runs, emits, drips or leaks can be repaired and repaired or replaced in time; The thermal insulation layer and reinforced lining layer are intact. Each shift shall regularly check the flexibility and working condition of the transmission device, and timely lubricate it to ensure its normal operation; Check and repair the fan, water supply pipe valve, water supply pump, etc; Check that all connecting pipe flanges and other parts of the boiler system must be tight without air leakage;
If the induced draft fan vibrates violently, it should be stopped for inspection. Generally, it is caused by wear of internal impeller, and it should be replaced; There shall be no accumulated water on the ground at the bottom of the boiler header and the heating pipe to prevent moisture corrosion of the base; Regularly check the shaft end seal, main shaft and electric device operation of the three-way baffle valve and remove the fault in time; Frequently check whether the boiler steam pressure, water level, superheated steam output and temperature are normal; Check whether the foundation anchor bolts are loose. It must be fastened, otherwise it will cause vibration.
waste heat Boiler manufacturer It means that the water level gauge must be flushed once per shift; Manual steam or water release test of safety valve shall be conducted at least once a week, and automatic steam or water release test shall be conducted at least once every three months; The pressure gauge shall be flushed once a week during normal operation, and the water trap shall be calibrated at least once a half year; The red line indicating the working pressure shall be marked on the dial, and lead sealed after calibration; High and low water level alarm, low water level interlock device, overpressure, overtemperature alarm, overpressure interlock device shall be tested at least once a month; The equipment maintenance and safety accessories test and calibration shall be recorded in detail, and the boiler operation management personnel shall conduct regular spot checks.
