Food factory difference between lancashire boiler steam boiler normal shutdown procedure which steps food factory steam boiler shutdown of normal What? For food factory, the sometimes off-season production or production needs to be suspended, are the need for shutdown operations, normal shutdown shall be provided for the shutdown procedure in accordance with the boiler safety rules is in order. If the middle improper operation, then there will likely lead to accidents. (1) a gradual decline boiler load, fuel is supplied to the furnace suspended, followed by suspension of the air blowing, the wind drops, eventually abort the wind. After gas boiler, furnace ceasefire, Fan continue for at least the wind more than talent 5min closed. (2) will take the initiative to manual water supply and water supply, adhere to the boiler water level slightly higher than normal level. (3) when the fire is reduced to the weak state, steam pressure has dropped, the steam supply discontinued, closing the main steam valve and steam barrier to the adapter main pipe. Boiler superheater, should open superheater outlet header properly discharge the steam trap, the superheater to cool, successively with the drain valve closed. (4) When the shutdown, the door is closed and the boiler outlet dampers. With a cast iron boiler economizer, economizer bypass flue damper should be open, but still Boiler Feed via economizer. Steel pipe economizer, the boiler water suspension, should open economizer recirculation pipes and valves; for no separable economizer bypass flue, economizer outlet water temperature should be close supervision, ensure economizer outlet water pressure corresponding saturation temperature is lower than 40 ℃ steam boiler. If the water temperature is higher than this temperature, turn on the water can be appropriately selected, Sheung Shui to cool down.
This passage will give you several tips on the use of the industrial boiler, including the choice of coal, the ignition points of attention, the internal rinse of the boiler, and the feed water requirements.
After thousands of trials boiler, proper selection of the parameters, compared with the conventional gas boiler, to save more than 20% area of lower capital requirements of the boiler room, the user inputs the cost is also reduced.
Central heating hot water boilers for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.
