The final step is to select which type of question and answer about coal operated steam boilers currently on the market have the type of fuel boilers, electric boilers. Due to the current state for the "coal to electricity," the advocate, more companies may choose an electric boiler, but there are energy consumption, safety issues such as the traditional electric boiler, by contrast, the crown than conventional electric steam boilers boiler energy saving more than 30% compared to conventional steam boilers have increased security.
About six tons of question and answer about coal operated steam boiler shutdown of a temporary shutdown: It is planned, therefore slow cooling during shutdown protection device, it should also pay attention to safety, pause furnace according to the rules in Chapter IV Fenghuo (pressure fire) get on. 2, safety shutdown: care should be completely stopped even on normal operation plan for 1 to 3 months to be a shutdown, shutdown should maintain more safety injection apparatus, after the shutdown, and other water-cooled furnace to below 70 ℃ when they let go of the gas, open manholes, hand holes, rinse the pot with water scale. 3, emergency shutdown: the boiler operation, when the case of the following circumstances, should an emergency shutdown, and notify the relevant authorities. (1) expanding the cease-fire should first see if the water table level is called to take water law. If Inception water table, water cock side, and then close the steam cock, and then turn on the water faucet open and close repeatedly called after water, still can not see the water. (2) All water supply equipment failure. (3) All water gauge, pressure gauge, safety one of all the failures. (4) a boiler or furnace wall element damage, serious threat to the safe operation of the boiler, emergency shutdown, should focus on preventing the stop of the accident and the specific steps as follows: ① first blowing off; ② the coal on the grate red raking; ③ Close induced draft fan.
