Horizontal coal-fired steam boiler, single drum longitudinally arranged three-pass fire tube structure, both sides of the furnace tube water wall tube light clouds, design reasonable and compact structure; a large heated area, gas flow long, coal-fired steam boilers, heat transfer effect, the exhaust gas temperature is low, so the high thermal efficiency, low running costs, the use of more economical. Coal-fired steam boiler shutdown steps: 1, gradually reduce the load, reduce the amount of coal supply air volume. When the load is stopped, then stop coal supply, air supply, weakening the wind, coal-fired steam boiler works, turn off the main gas valve, open the trap superheater and economizer bypass flue baffle, closed economizer main flue baffle. 2, before the complete shutdown of coal-fired steam boilers, coal-fired steam boiler classification, the water level should remain slightly above the normal water line to prevent water shortages caused by the cooling water level drops. Then the wind stopped, closed dampers, Bachu unburnt coal in the furnace, remove ash. Then close the door and ash door, coal-fired steam boiler specification, prevent rapid cooling boilers. When the boiler pressure is reduced to atmospheric pressure, open the air valve lift safety valve, in order to avoid negative pressure inside the drum.
