CFBC boilers are generally more economical than AFBC boilers for industrial application requiring more than 75 – 100 T/hr of steam. For large units, the taller furnace characteristics of CFBC boilers offers better space utilization, greater fuel particle and sorbent residence time for efficient combustion and SO2 capture, and easier application of staged combustion techniques for NOx control than AFBC hot sale small steam generator prices.
Boiler and its output illustrate the transformation of the group in terms of power generator: boiler, which usually have several parts which? Shell boilers, which in turn is a kind of boiler? In addition, the boiler output and power generating units, among them how conversion? These issues are on the boiler, and also we must know and master, so as to deepening the boiler products, thus, continue to acquire new knowledge in order to reach a predetermined learning objectives and requirements as soon as possible. 1. transformation of the boiler, which is typically what parts there? Boiler, part of it contains mainly two, which is specifically as follows: First, the pot of transformation, however, be noted that the transformation of its approval, is slightly more complicated, and that will take some time . First of all, there is a qualified design units to come up with rehabilitation programs, and then to the local Bureau of Technical Supervision approval, after approval by the boiler is to examine the record. When the transformation is complete, but also to test the boiler inspection. After the inspection, you can start using. Second, it is part of the transformation of the furnace, but this is much simpler, as long as the right boiler pressure part of the transformation, the transformation of other parts, is not required by the supervisory inspection. 2. shell boiler, which in turn can what? Shell boilers, which in turn can call fire-tube boiler, in its formal structure, generally a two-layer jacket. And that the outermost, is boiler shell, called the inner tube furnace. The media, is between the outer cylinder and the inner cylinder flows. Therefore, when this kind of boiler pressure, the boiler shell is subject to internal pressure, external pressure by the furnace.
Recently, Jinan City issued a "supplementary notice on accelerating the city's boiler-depth treatment of work-related" and formulated the following objectives.
I, on the in-depth treatment of boiler completion time. Low Nitrogen transformation and the transformation of the city's ultra-low emission gas-fired boiler biomass boiler to complete the appropriate time to relax, and strive to be completed in the end of June 2019, due to the commitment of heating (cooling) or involving people's livelihood and other support complex transformation process of the boiler furnace, indeed practical difficulties, completion time may be extended to the end of October 2019.
Second, on the in-depth treatment boiler standards. According to the "program tackling autumn and winter", the low nitrogen gas boiler after transformation, in principle, is not higher than the concentration of nitrogen oxides emissions of 50mg / m³, according to encourage the transformation of 30mg / m³. Encourage the transformation of biomass boiler with ultra low emissions coal-fired power plants.
Third, on the time-depth treatment of boiler arrangement. 2018 10 completed before the end inventory information verification, planning work; organize the implementation of the completion of the work before the end of May 2019; the end of June 2019 to complete the inspection work (due to heating and other disabled do not have to bear the acceptance conditions, available at the end of November 2019 before the completion of acceptance).
Fourth, on the information submitted to the work. Please ring the economy Zi  No. 175 document complements the "Jinan City gas boiler investigation Summary Sheet" on or before October 12, "Jinan biomass boiler investigation Summary Table" to the Municipal Environmental Protection Bureau. On or before October 26, the "Jinan City Boiler depth management plan summary table", "Jinan hole sampling and sampling platform standardization construction unit summary table" and has completed the in-depth treatment of the boiler reconstruction proved supervisory monitoring report submitted to the Municipal Environmental Protection Bureau . Since the beginning of November, every Friday morning before 10:00 (for the first time submitted November 2) the progress of reform in-depth treatment of each unit case to the Municipal Environmental Protection Bureau.
Xiao Bian tell you about the boiler combustion optimization control of those things: the boiler is an energy conversion device, in other aspects of power plant systems have been developed under perfect circumstances, boiler combustion system is a major part of energy-efficient coal-fired power stations and savings. Now, with the burner technology is improving daily, it has been able to adapt to all kinds of fuel combustion conditions and load, but the new requirements of energy saving power companies makes burning power plant boiler combustion stability not only meet, but also to meet the combustion process efficiency and reduce pollutants requirements emissions. It is necessary to further optimize the combustion process and operation. Today, we learn more about it. Generating hot water or steam boiler may directly provide the necessary heat for industrial production and the people's life, by a steam power plant can be converted into mechanical energy, or through the generator converts the mechanical energy to electrical energy. So, generally we use combustion expert system to monitor the implementation process, maintaining the boiler combustion efficiency and energy saving. Automatic water boilers, reaching full of water replenishment stops automatically, not manned, save time, save time, effort, labor. Increasingly comprehensive boiler combustion control means and the cumulative operating experience, providing adequate conditions for the implementation of expert systems. By burning power plant boiler combustion expert system of real-time status monitoring, by the mathematical model and expert system established by the corresponding combustion, can effectively adjust the boiler combustion, state correction due to various factors to the combustion process caused by deviation, to achieve optimal control of combustion. Structure designed according to the boiler pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination aesthetic aspect. When using the boiler operation, hold down the control key forced to manually start and stop the boiler with water, the water level reaches very low safety level, the boiler automatically stops pay, the microcomputer controller after setting the boiler, the boiler began to work fully automatic, automatic replenishment, automatic heating, when the set temperature is reached, the boiler into the automatic insulation state. The coal boiler according to data analysis, secondary air damper temperature, and the load carried by the boiler combustion conditions, the coal and air flow control system to protect combustion boiler at its best, achieve fuel economy, reduce emissions of pollutants. The experience of the steel and building materials industries, the expert system can be achieved using combustion burn energy saving 2% -5%. You know what Btu boiler is not it?
