heat recovery steam generator price in bd boiler
Boiler work principle in thermal power plant:Industrial boilers provide the steam needed during industrial production.Boiler generate high temperature and high pressure steam through the nozzle in turbine blades, the rotating blade and drive the generator rotor to rotate to generate electricity.
Environmental advantages atmospheric boiler which specific environmental pressure boiler boiler belong to a classification of the product's advantages are the following 4:01, energy: environmental pressure steam boiler smoke can be converted into a gas burner saving coal consumption. Atmospheric environmental protection boiler combustion chamber is provided with two double grate above the combustion chamber if no burning coal fell well below the combustion chamber can continue to burn. Also provided primary air, secondary air give sufficient oxygen fuel combustion. According to the user site using the same contrast ratio bituminous coal boilers save about 30% than coal boilers save about 50% and so on. 2, environmental protection: environmental protection atmospheric boilers can burn a variety of bituminous coal and can be quickly converted into a gas burning chimney smoke is not black smoke purification fine dust and sulfur dioxide by monitoring the indicators have reached the national environmental standards. 3, reliable quality assurance: environmental pressure boiler steel plate is used in the national standard steel plate material Q235A, Q235B, international seamless steel pipe made of 20, GB3087, GB8163 production materials and manufacturing processes are in strict accordance with national standards. After testing various indicators have reached the national standard. 4, safe and reliable operation without pressure: atmospheric environmental protection boiler structure is very compact footprint not much on the temperature quickly is no safe and reliable pressure operation. SPLIT boiler arrangement, high capital investment, an area of large, coal adaptability is poor, complicated operation. Boiler output gas generator speed susceptible to impact, heat loss and clogging of piping and other problems tar gas delivery.
Shandong Province is China's new energy equipment industry started earlier, more mature industrial system of provinces and cities in recent years, the overall strength of continuous improvement, a good momentum of development. 2017, the province's new energy industry added value to around 110 billion yuan. In recent years, around improve air quality and reduce consumption of coal and other fossil fuels, Shandong Province, adjust and optimize the energy structure.
Recently, Shandong Provincial Government issued "Shandong Province, the new energy industry development scale (2018-2028 years)," Planning, pointed out: will adhere to local conditions, advance planning, rational distribution, diversified development and scientific resources to promote biomass as energy recycling and clean use. In the northwest, Shandong medium straw-rich areas in the construction of straw-based biomass power generation projects; gathering area in Lunan wood processing and straw-rich regions in the construction of agricultural and forestry biomass power generation projects; fruit tree branches in Shandong Peninsula firewood resource-rich regions, temperatures promote urban domestic garbage power generation project. In the industrial wastewater mailing harmless treatment concentrated areas and livestock scale farming areas, rational distribution of biogas power generation project. And strive to 2022, the province of biomass power generation capacity of around 3.5 million kilowatts; by 2028, the province's biomass power generation installed capacity reached 500 million kilowatts. The plan also proposed to play the advantages of Shandong Province as the province of biomass resources, focus on breakthrough high efficiency and low nitrogen biomass combustion, gasification coupled power generation, cellulosic ethanol, biomass aviation fuel, biomass olefins, biomass and other biomass graphene energy thermal conversion and biochemical transformation and other key technologies, key equipment focus on promoting biomass boilers (kilns), briquette, power generation equipment, advanced gasification, carbonization, in areas such as biological fermentation research and development and industrialization, a series products and scale production capacity, cultivate material and equipment manufacturing, high-value product development, integrated services group of students and other characteristics of key enterprises, and strive to build a diversified use of biomass demonstration provinces. 2022, the province's biomass energy industry output value and strive to exceed 40 billion yuan; to 2028, the province's biomass energy industry output value and strive to reach 600 billion yuan.
Another technology being incorporated by boiler manufacturers is the gas turbine.When a gas turbine is used, natural gas is fired, and the hot gasses are used to spin a turbine attached to an electrical generator to make electricity.Since there is still available heat in the gas that exhausts from the turbine, it is then sent through a Utility Power HRSG (Heat Recovery Steam Generator).Similar to a watertube boiler, the hot exhaust gasses from the turbine heat water in the tubes of the utility power HRSG and turn it into steam, which is then used to turn a second steam-driven turbine attached to another electrical generator.This technology is called “Combined Cycle Cogeneration”, and is a very efficient use of fuel because the same fuel source is used twice to drive turbines.
