Product introduction

  As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm. CFBC can desulfurize directly during the combustion process, and the desulfurization efficiency is high. The technology and equipment are simple and economic, and the costs of its initial investment and operation are much lower than those of dry pulverized coal furnace and flue gas desulfurization (PC+FCD). The discharged ash residue has good activity and is easy to be comprehensive utilized without secondary ash residue pollution. The load adjustment range is large, and the low load can be reduced to about 30% of the full load.

High temperature cyclone separator
  • High efficiency, wear resistance, separation efficiency ≥ 98%, effectively improve the combustion efficiency of the boiler thermal efficiency.

Large furnace design
  • Large furnace, low velocity design; the application of wearproof tube technology, reducing erosive abrasion.

  • Extend the residence time of coal particles in the furnace so that the coal can be fully burned.

Bell jar type hood
  • Adopt bell type hood to distribute air averagely and avoid fuel reverse to wind chamber.

Low bed pressure operation
  • By particle optimization, the operating bed pressure can be decreased to 3500Pa, which effectively saves operating costs and greatly reduces the oxynitride generated.

Economizer - WikipediaEconomizers (US and Oxford spelling), or economisers (UK), are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid.The term economizer is used for other purposes as well. Boiler, power plant, heating, refrigeration, ventilating, and air conditioning uses are discussed in this article.Feedwater heater - WikipediaAn economizer serves a similar purpose to a feedwater heater, but is technically different as it does not use cycle steam for heating. In fossil-fuel plants, the economizer uses the lowest-temperature flue gas from the furnace to heat the water before it enters the boiler proper. This allows for the heat transfer between the furnace and the feedwater to occur across a smaller average Talk:Economizer - WikipediaThis article is within the scope of WikiProject Physics, a collaborative effort to improve the coverage of Physics on Wikipedia.

Subcooling - WikipediaEconomizer and energetic efficiency. Subcooling phenomena is intimately related to efficiency in refrigeration systems. This has led to a lot of research on the field. Most of the interest is placed in the fact that some systems work in better conditions than others due to better (higher) operating pressures, and the compressors that take part Boiler Economiser : Definition, Function & Types of Boiler Economiser: Boiler Economiser ( Sometimes Called Economizer ) is the Energy improving device that helps to reduce the cost of operation by saving the fuel.. The economizer in Boiler tends to make the system more energy efficient.. In boilers, economizers are generally Heat Exchangers which are designed to exchange heat with the fluid, generally water.

Heat recovery steam generator - WikipediaA heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycleSteam-electric power station - WikipediaThe steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser.The greatest variation in the design of steam-electric power plants is due to the different fuel sources.
