steam for a 1 mw 5mw generator

Vietnam Biomass CFB steam for a 1 mw 5mw generator in Sugarcan Mill Technology

The prime technology for sugar mill cogeneration is the conventional steam-Rankine cycle design for conversion of fuel into electricity.A combination of stored and fresh bagasse is usually fed to a specially designed furnace to generate steam in a boiler at typical pressures and temperatures of usually more than 40 bars and 440°C respectively.The high pressure steam is then expanded either in a back pressure or single extraction back pressure or single extraction condensing or double extraction cum condensing type turbo generator operating at similar inlet steam conditions.

With the urban heating developing with a modern, large-scale, centralized heating trend, in 2009, the company bought two 116MW circulating fluidized bed steam for a 1 mw 5mw generator and two bearing generators steam boiler, not only to meet the city construction of rapid development needs, and enterprises to embark on the road of development of cogeneration.

Combined heat and power (CHP) introduction

Cogeneration, refers to the heat and power plant in the same joint together, shorted as CHP (combined heat and power). CHP plants have been ordinary waste heat to be utilized to provide cheap heating heat for industrial and household use, which can greatly improve the thermal efficiency. Typically thermal power, its efficiency is about 30 to 35%. This means that for every 1 mega-joule energy output, there are two mega-joules of heat wasted. This part of the heat of re-used to heat water, fully meet the heating needs of the plant and the residential area near the plant. CHP usually drive a steam turbine generator, and the exhaust heat is used to complement the existing boiler plant, the total efficiency of up to 80%.

Luzhou, Sichuan issued a notice to win the Battle of Blue Sky embodiment. Program requirements, to promote ultra-low emissions to upgrade the steel and cement industries, and increase efforts to eliminate small coal-fired steam for a 1 mw 5mw generators, phasing out the whole 10 tons / hour and below the coal-fired boilers. Details are as follows.

1, to accelerate the development of clean energy. Scientific and orderly promote clean energy development and utilization of hydropower, natural gas (shale gas), wind power, solar, biomass and so on. By 2020, the city's total primary energy consumption of 12.48 million tons of standard coal, total coal consumption control in less than 6.5 million tons, accounting for the proportion of total energy consumption control in less than 42%, the newly constructed and put into operation a large municipal solid waste incineration power plants, garbage power generation capacity of 12MW, a new wind farm installed capacity of 48MW, the development of distributed PV installed capacity of 5MW, the new large biogas 5. Improve the construction of reservoirs for natural gas production and marketing system.

2, to promote the use of clean coal. Efforts to increase coal washing, coal simultaneous construction of new coal washing facilities, supporting the completion of existing coal mines coal washing facilities in accordance with points Area. Improve coal quality and use of standard industrial, commercial coal do not comply with environmental standards required by regulations of coal quality merchandise. Prohibit the circulation and use of low-grade bulk coal, bulk coal investigated and dealt with according to the law without a license behavior. Increase the civil bulk coal clean governance efforts to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves, strengthen civil bulk coal management. Strengthen regulation and control coal use in autumn and winter.

3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. By 2020, the county level and above cities phasing out the built-up area per hour and 10 tons of steam coal-fired boilers, in principle, to a new 35 tons of steam per hour of coal-fired boilers, in principle, to other parts of the new 10 per hour tons of steam coal-fired boilers. Ambient air quality standards are not areas should further increase efforts to eliminate.

4, increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network and bulk coal fired boilers within the coverage area. In areas not have cogeneration district heating conditions, a plurality of existing coal-fired boilers of small, actively promote the implementation alternative energy.
