high performance vertical gas fired steam boiler
Second, the clear purpose boiler "coal to gas"
1, while maintaining the original nominal parameters of the boiler (e.g., steam temperature, steam pressure, water temperature, etc.) remain unchanged, maintaining or improving output and efficiency of the boiler.
In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving high performance vertical fired steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
Fuel high performance vertical fired steam boiler fuel steam boiler: Features: 1. Reburning fuel steam boiler corrugated liner tee horizontal central fire tube structure absorbs most of the heat, high temperature flue gas when the flue gas reaches the wheelhouse, may be reduced to 720. deg.] C, lower than 400 deg.] C or more other structures, thus greatly improving the the operating conditions of the boiler tube sheet area evenly heated. The present invention reduces the scale of production, prolong the service life; burning back at the center of three-loop configuration, when the return uncombusted portion two loop complete combustion at high temperature, the fuel can be burned again, generation of NOx is reduced, saving energy, effective protection of the environment. 2. The use of threaded pipe, a corrugated liner, advanced technology and good thermal expansion properties, clever use of the thermal expansion of the inner bellows and cold shrink, strong turbulence and good interference properties, high heat transfer coefficient, high thermal efficiency. three. Expansion tank located in the upper boiler, the water level to facilitate inspection and an exhaust port having a diameter of 400mm, to facilitate inspection and maintenance the boiler internals. 4. The introduction of Western Europe original combustion engine and automatic computer control devices, reliable operation of computer disk unit over-temperature protection, water protection, fault protection and self-flame burner malfunction alarm functions, ensure that the boiler safe and normal operation; respectively combustion machine the first stage ignition and the second stage ignition control, and record the operating time of the burner, in order to ensure economical operation of the boiler, reducing fuel consumption. Temperature control set free, clock function, the oil level control, automatic fault-point display, 04: 00 to facilitate the daily time switch functions, operation and management. The direct heating to produce hot water, the heat exchanger may be used in a multiple stage machine. The heating temperature can meet different requirements, to provide a hot water bath. 6. It can be used with a heat exchanger, in order to meet the needs of high-rise buildings; water-cooled grid, cool, less investment, effective, and long service life. 7, after the wet structure, hinged front panel open structure, easy maintenance and repair. Eight. Atmospheric design, absolutely safe; smoke-free clean, in line with national environmental requirements. 9. The outer mirror stainless steel or cold spray, nice.
Gas boiler which has few parts of the main gas boiler: the enclosed pipe chimney pipe tube sheet base gas outlet steam dryer Confining the majority of the peripheral tubes to form a complete gas boiler. The main effect of gas boiler: the combustion of the fuel is heated by the feedwater temperature and the exothermic heat of the flue gas with a heated surface, so that a final water into superheated steam having a quality of qualified certain parameters. The water in the boiler to go through preheating, evaporation, overheating in three stages in order to become superheated steam. In fact, in order to improve the efficiency of the steam power cycle, there is a fourth stage, i.e. re-superheating stage, soon after the high pressure turbine expansion work to reduce the pressure and temperature of the steam back to the boiler is heated and then sent to the low pressure turbine cylinder continues to work. In order to meet these four phases change, the boiler must be arranged in the respective heating surface, i.e. the economizer, water wall, superheater and reheater. Superheater and reheater disposed in an upper horizontal flue backpass and functions of the fuel system is to ensure the desired fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The gas burner mainly a filter, pressure regulator, solenoid valve, and then firing solenoid valve, the fuel valve. Economizer disposed in the lower back pass. In order to utilize flue gas heat of heated air required for combustion, usually air preheater arranged after the economizer. Some additional preheating large boiler superheater heating surface or in the furnace, and then heat-receiving surface.
