thermal efficiency of steam boiler
Harbin Thermal Power Co., the main city of Harbin is the largest cogeneration business, the company bear the city's heating area of 24 million square meters, to provide heat supply for more than 400 agencies, enterprises and 140,000 residents. Currently, the company is actively respond to the latest environmental standards introduced in China, the group mobilized up and down, stepping up technological innovation, upgrading environmental protection facilities, the project is expected to complete upgrading coal-fired boiler at the end of this year.
Harbin Thermal Power Co., the existing five boilers for heating and power generation: where to cogeneration units No. 7,8,9, and the other two hot water boilers. No. 9350 MW units which since 2017 was completed and put into operation, has achieved ultra-low emissions standards during construction. 7, No. 8 is 300 MW units were built in 2005 and 2006, these two units of environmental transformation began in 2013. Harbin Thermal Power Co., according to the latest environmental requirements, environmental upgrading facilities. First, soot emissions transformation, the introduction of advanced electric bag filter, followed by addition of sulfur, in addition to the transformation of nitrate, new burners in addition to the low nitrogen oxides of nitrogen, a wet desulfurization technologies in addition to sulfur dioxide. After four consecutive years of continuous transformation, 7,8 units in 2017, all the transformation is completed, achieve ultra-low emissions standards. For the two 116 MW hot water boiler was built in 2013, it has long been included in the transformation plan. Earlier this year preparatory work has been completed and environmental transformation has entered the bidding process in mid-October to start construction, completed renovation project at the end of December.
Steam boiler in Henan natural circulation pump and clean fast boiler's thermal efficiency of steam boiler Xiao Bian told you about in the natural circulation pump and clean natural circulation boiler is the use of the density difference circulation loop rise and fall pipe soda mixture with water in the pipe to establish the working fluid cycle. Having a drum, a radiation heating surface, convection heating surface and a button connected to a steam boiler, a steam separator, and a larger heat storage capacity of water, more reliable water cycle, water separation was also better. But the drum heat capacity, simple wall thickness, temperature, and speed limits start and stop the boiler drum manufacturing, transportation and installation is also more difficult. Natural circulation boiler further includes two types: a steam boiler, and such a boiler is divided into: 1) Simple cycle: on the drum, the downcomer, the lower header tank or drum, and also some of the riser pipe constructed in parallel there are upper header. 2) Complex cycle: different conditions riser group consisting of linked together by common circulation circuit member. Two hot water boiler in the natural cycle further includes the following three: 1) the whole natural circulation: In addition to an outer surface heating radiation, convection heating surface are all working according to the natural circulation, the use of heating surface bundle structure. 2) Natural circulation predominant: radiation heating convection heating surface area for the most natural circulation, convection heating surface portions of the work by directly using serpentine configuration. 3) semi-natural circulation type: radiation heating surface is natural circulation, convection heating surface by all DC operation, serpentine tube means. Natural circulation boiler For ultra high pressure steam boiler or less, more subcritical pressure employed, but the soda density difference decreases, weakening the flow head, high purification of the steam separator and steam requirements, the highest pressure of 17.3 MPa, the capacity to 2350t / h. Oil cleanliness have a significant impact on the life of the hydraulic pump, in addition to the requirements set forth above, the user must also pay special attention to the following points: 1, must be fuel tanks, pipes, hydraulic cylinders and hydraulic before installing, commissioning clean valves, etc., of the oil must be filtered oil vehicle when filling new oil to the tank, to prevent the contamination caused by the dirty barrel of oil. 2, must be prevented during transport, since the disassembly packing conduit pipe caused by contamination, and the tank element. Thus, hydraulic oil tank and other devices as far as possible the overall packaging system, as few as possible detached pipe, tubing and fittings must be disassembled at all sealed with a dust. 3, the new pump one week after use, the need to once all the oil filter, oil and the oil filter and washed, and then according to machine work load situation 3 to 6 months to replace a fluid, a cleaning tank. 4, during use of the system is prohibited due to heat generation and the injection hole or opening the fuel tank cap.
Gas hot water boiler may be provided in different modes according to the actual needs of the user, such as low temperature mode, the high temperature mode and the like.
