High Temperature Coal Fired Steam Boiler
On the ISH heating HVAC industry event, fast Boiler bring new products customized for the paper and packaging industry well-built --- Euromonitor θ5 stunning debut, attracting various participants competing concerns. The product closed condensate recovery system, temperature condensate directly into the boiler design, three-pass boiler with economizer + + structure air preheater for recycling heat from the high temperature condensed water source, the thermal efficiency of up to 95%, to save operating costs with immediate effect.
IBR CFB Steam Boiler
ZG manufactured IBR CFB steam boiler can be distinguished into new type water cooling whirlpool inner separation low speed circulating fluidized bed boiler and energy saving circulating fluidized bed boiler. IBR CFB steam boilers’ capacity is among 15 to 280 ton/h. IBR CFB steam boiler can also be divided into coal fired CFB steam boiler and biomass fired CFB steam boiler. CFB steam boiler can be widely used into paper industry, textile industry, oil refineries, power plants, chemical industry, glass plants, and so on. Besides, 75 ton coal fired CFB steam boiler is the hot sales product in our ZG Boiler.
About six tons of high temperature coal fired 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.
6 tons gas high temperature coal fired steam boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.
