4 tph WNS series two-pass natural gas steam boiler project for aluminum industry

Founded in 2007, Jiangsu Dalishen Science &Technology Co., Ltd. is mainly engaged in the research, development and production of aluminized zinc (steel coil), color coating (steel coil), high-precision silicon steel plates. With multiple (aluminum) zinc plating production lines, color coating production lines and silicon steel lines, Dalishen has constructed four phases of projects. This fifth phase of the project is a heat supply project for the high-precision silicon steel production lines. A new set of natural gas boiler will be adopted to supply steam for the internal silicon steel production and waste acid treatment.

Why should regularly boiler decoking and put ashes? All contain a certain amount of the solid fuel ash, coal-fired boiler combustion process fly ash and cinder there will be generated, cinder ash hopper falls cold fly ash particles may fall into a large economizer while passing through the tail, discharge hopper in an air preheater, and then you need to put the ash slag periodically, in order to avoid plugging and blocking ash residue. In addition to focus and put the ash is not timely, it will cause Heating Surface temperature rise, so that the heating surface coke heavy, causing steam temperature rise, damage the water cycle, increased exhaust loss, when coke is serious, it will result in boiler output decline. When severe fouling, can also block the tail channel, even forced shutdown for maintenance.

10 tons of gas 116 mw hot water boiler design chemical engineering depreciation calculation depreciation is due to the gradual loss of fixed assets transferred in the course of the merchandise or the cost of that part of the value to go, but also business due to the use of fixed assets used in its production process assessed useful life of fixed assets cost money. 10 tons of gas hot water boilers are industrial boiler, equipment belonging to the class. In accordance with the Enterprise Income Tax Law, depreciation of fixed assets a minimum period of 10 years, residual rate set at 5% or 10%. If the 10 tons / hr of a gas hot water boiler for heating use, should process equipment, mutatis mutandis, the age of 10 years. In calculating the depreciation of fixed assets, in addition to foreign-funded enterprises to deduct the residual value according to the proportion of 5%. Assuming that the cost of 10 t / h of gas hot water boiler purchase of 500,000, the annual depreciation amount of the boiler: 500000- (500,000 * 5%) / 10 = 497,500 yuan. Suppose residual rate set at 5%, is expected to use for 10 years, the 10 tons / hour of industrial gas boiler depreciation rate = (1-5%) / 10 * 100% = 9.5% of the 10 t / h of gas hot water boiler monthly depreciation rate = 9.5% ÷ 12 = 0.79%. The monthly depreciation 10 tons / hour gas hot water boiler = 0.79% * 500,000 = 3950 yuan. In recent years, as an environmentally friendly gas-fired boiler to get the type of boiler widely welcomed by all walks of life, whether it is the depreciation rate for the gas boiler, the initial investment, annual operating costs and environmental aspects of government policy, gas boiler has played a great advantage.
