During cleaning, boilers are fired at a low rate, but not enough to establish positive circulation. Boil-out pressure is usually about half the operating pressure. Several times during the alkaline boil-out, half of the boiler water should be blown down as shown on the gauge glass through the bottom blowdown valves.Get Price
Water tube boilers raise steam fast because of large heat transfer area and positive water circulation. external erosion from burners and flue gas, possible corrosion on the boiler side, and; As an alloying element, manganese serves as an inexpensive means of preventing "hot shortness". It improves rolling properties, hardenability, and Get Price

A special feature of the boiler house structure at Lethabo is its 82,6 m high concrete superstructure with its sliding-shutter building technique. This type of structure, already employed at Matla Power Station, compares very favourably in technical as well as cost terms with the more conventional steelwork structure.Get Price
Mar 09, 2017 · Typically, the efficiency of boilers is between 70 and 80% depending on how well the boiler is maintained and what type of boiler it is. Second part is the vapour cycle efficiency. It plays a major role in steam power plants.Get Price
The water leaves the boiler tube at 50 bar and 700oK at velocity of 100 m/s. Calculate the inlet volume flow (L/s) From steam tables: at 70 bar (7MPa) at 65oC v1 = 0.001017 m3/kg at 50 bar (5MPa) and 700 o K (427oC) v2 = 0.06081 m3/kg a. 0.821 b. 1.261 c. 0.344 d. 1.609 Water substance at 70 bar and 65oC enters a boiler tube at constant inside Get Price
Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.Get Price
