hot water boiler for bath price
Gas boiler water treatment is very important, we must pay attention to it: gas boiler proper treatment can prevent scaling, corrosion and other problems, effectively extending the life of the boiler. But at this stage, there are still a lot of water problems.
As we all know,boiler thermal efficiency is calculated fuel’s low calorific value.does not consider the high calorific value of the fuel heat loss in the amount of the latent heat of vaporization.Therefore,the boiler thermal efficiency is generally only reach 70 to 85 percent.Thermal efficiency is about 80%,about 20% of the heat distributes from the furnace surface and wastes smoke evacuation.
Shutdown operating steam boiler steam boiler shutdown is divided into two kinds, the temporary shutdown (within three days), complete shutdown (shutdown or overhaul more than three days). A steam boiler temporary shutdown: 1, according to the actual situation, the appropriate weakened combustion, stopping the steam, followed close blower, Fan, grate steam sector. 2, until the furnace temperature dropped to fire when the pressure starts 400 ℃, covering the layer of wet combustion of coal seam, close the damper, coal down the shutter, open the exhaust valve exhaust. 3, the boiler water level to be adjusted to a vapor pressure drop 0.15MPa when the maximum operating level, closing the main valve until the furnace temperature dropped off when the main power 200 ℃. 4, run the table in the line of steam boilers make a record, do the work of changing of the guard. 5, steam boiler pressure during the fire need to have someone on duty to prevent coal combustion and boiler water and other accidents. Second, the complete shutdown steam boiler: 1, the steam boiler is stopped an hour earlier coal supply steam, the steam to be sequentially turned off after stopping blower, Fan, grate. The excess coal in the coal hopper picking out, open grate, coal and slag in the furnace cleaned up. 2, adjust the boiler steam boiler water level to the maximum working level if the shutdown to one week, open the exhaust valve, the pressure to be reduced to 015MPa, the main steam valve closed. 3, steam boilers quickly opened if the maintenance or long-term shutdown, the pressure drop 0.4Mpa all drain valve, drain the boiler water, dried using waste heat boiler and do respond to treatment. (Note: You must turn off the furnace temperature drops after about 200 ℃ can turn on the water). 4, turn off the main power shutdown, make relevant records on the operation table boiler.
