High efficient steam generator from China supplier
30 MW coal fired power plant boiler working principle
30 MW Coal-fired power plant boilerproduce electricity by burning coal in a boiler to heat water to produce steam. The steam, at tremendous pressure, flows into a turbine, which spins a generator to produce electricity. The steam is cooled, condensed back into water, and returned to the boiler to start the process over.
Recently, the market supervision bureau Zhoushan Development and Reform Commission and the relevant district towns, streets and CMC, 35 steam tons / hour and below the coal-fired boilers situation within the region to conduct a comprehensive diagnostic investigation, and to develop in accordance with the relevant requirements of provinces the remediation plan, renovation of existing enterprises to carry out classification boiler eliminated.
Accelerate the phase-out of coal-fired boiler renovation work is to win the Battle of the sky, to lay an important task for the campaign of prevention of pollution. In recent years, Putuo District of Zhoushan City, to speed up the adjustment of energy structure, and actively encourage enterprises to adopt "coal to gas," "coal to oil" as well as central heating and other measures. By the end of 2018, the district has completed the elimination or modification for 10 steam tons / hour coal-fired boilers 175 units, effectively promote pollution reduction work.
According to "Zhejiang win the Battle of Blue Sky three-year action plan" requirements, by 2020, the province will be basically eliminated 35 tons of steam / hour and coal-fired boilers, more than 35 steam tons / hour of high pollution and energy-saving ultra-complete boiler low-emission transformation. Next, our region will be based on the unified arrangements of provinces and cities, and actively practice the concept of green development, continue to promote the 10-35 tons of steam / h coal-fired boiler out of rectification work to further improve the air quality in Putuo District.
Gas heating boiler in the choice of which areas need attention construction, industrial, life most needs to heating boilers, hot water boiler then what the election or steam boiler heating? How much tonnage, how many? And how to make choice boiler energy-saving and environmental protection? these questions will undoubtedly cause great distress customer, the following solve these problems, we can do a simple discussion, consider providing some feasible ideas. A. How to determine the tonnage and the number of boilers must first be calculated from the area of heating and domestic hot water heat demand of the total amount for this issue. Meanwhile, in the calculation of the process, also taking into account factors external architectural features heating areas, temperature characteristics, the peak water heating, etc., due to local conditions at the time. Then, after completing a comprehensive evaluation, will be able to consider the issue of tonnage and number of units furnace, then how should the election, which requires analysis to analyze the results of previous projects using features of the boiler, but also to figure out the actual boiler operating efficiency, as well as tonnage and heat supply matches demand real problem customer site. II. When selected gas heating boilers, steam boilers or hot water is selected by boiler application analysis of many companies, both on a simple comparison, you will find hot water boiler will be energy efficient than steam boiler, so if there are energy-saving project demand, suggested the use of hot water boiler. Of course, both need something like hot water and steam needs, you need to hotels, hospitals and other places to determine the actual situation. If a large amount of hot water heating system, requires a small amount of steam, it is recommended to install a small steam boiler or high efficient steam generator from china supplier outside of the hot water boiler, in order to meet the needs of a small amount of steam. For example, a hospital or a star hotel's steam demand does not exceed 30% of the total heat demand. According to practical experience, low load operation efficiency of the steam boiler and attenuation is large, the system energy losses. Final energy efficiency is only about 60%, serious waste of energy. III. How to select energy saving gas heating boiler from the heat required systems, combustion systems, control systems and other consideration, and that is in heat transfer systems, taking into account the use of materials heat exchanger, steel, copper or iron, which according to their comparative property, currently used is copper; boiler combustion system is the key to determine whether the device is energy saving. Combustion methods currently used are: premix combustion method, atmospheric premixed combustion and the diffusion combustion method. But just in terms of energy savings, premix technology would be more advantageous, it pre-mixed air and gas, multi-mode radiator heat, the intensity of the heat transfer improved. The advantage of using this method is that the combustion flame combustion clearer, and higher thermal efficiency.
Gas steam boiler is a high quality steam release device: gas steam boiler combustion of the fuel delivery device is a high quality steam, essentially the primary energy (burned gas) into secondary energy (electric power) of the energy conversion process, thermal power plant, the gas high temperature and pressure steam produced by the boiler steam turbine driven, drive electric power generated by the generator, so that the boiler is one of the three main power plant equipment.
