energy saving coal fired dhl boiler
Advantages of heating Boiler and Gas-fired heating BoilerOil-fired and gas-fired heating energy saving coal fired dhl boilers all belong to chamber-fired boilers. The fuels used are injected into the furnace by burners and no cinder will be produced after combustion. This type of heating boiler does not require the complex and huge crushing of coal-fired boilers, facilities for conveying tender coal and equipment for burning and dedusting, so it is compact in structure, small in size, light in weight, small in land area, small in pollution and high in automation. Cities and boiler houses that require high environmental protection and prohibit the use of coal-fired boilers are used in large quantities in areas and units with high technical requirements for heating regulation. Medium and small boilers generally use light diesel oil, large-scale oil-fired boilers burn more heavy oil. Due to combustion The boiling point of oil is always lower than its ignition point, so the fuel is usually gaseous. After heating, the fuel is vaporized into oil vapor. After the mixture with air reaches a certain temperature, it starts to ignite and burn. In order to enhance the degree of vaporization of fuel, the fuel is often atomized into small droplets into a man-made furnace, heated by high-temperature flue gas in the furnace, and quickly vaporized and mixed with oxygen in the surrounding air, starting to ignite and burn. Some of the heat after burning is passed to the oil droplets, which vaporize and burn until they are exhausted.
CFB energy saving coal fired dhl boiler is a new technology in boiler research,CFB boiler have strong adaptability in fuel choice.Coal,oil,gas and biomass all of these can be used in CFB boiler as furl.But among this biomass is the most energy saving and environmental friendly fuel.
August 10, 2018, Shanghai Industrial Boiler Research Institute Co., Ltd. (hereinafter referred to as the working pot), the National Boiler and Pressure Vessel Standardization Technical Committee of Professional Committee of energy saving coal fired dhl boiler energy conservation (hereinafter referred to as the Commission) was held in Chengdu, organizational GB / T16508 "shell boilers" revision of the second meeting of the reported revision of the second meeting, the main author of this standard, pot capacity standard Committee appointed sub-standard boiler, the special committee secretariat a total of 10 experts attended the meeting.
Organized by the Shanghai Institute of Industrial Boiler Co., Ltd. Deputy General Manager, committee chairman Wang Shanwu chair. He said the main author of the unit where the standard of support GB / T16508 standard revision of thanks and hope the standard revision process experts complement each other, support each other, the GB / T16508 benchmark revision as the boiler industry standardization work seriously treat, carefully modified. Amended in accordance with the basic principles of the first meeting to determine, in addition to technical support for the "Boiler Safety Technology Supervision" (referred to as "Boiler Rules"), but also take into account the needs of industrial boiler manufacturing enterprises, between consideration and GB / T16507 harmonization. At the same time listen to opinions, to further enrich the standard revision work force, give full play to industry leading products representative firm.
Yung pot boiler Technical Committee Standards Committee Secretary-General Zhang Rui introduced GB / T16507.1 "The first part of the water-tube boilers: General" and GB / T16507.2 "The second part of the water-tube boilers: material" revised draft of the general framework and main content.
Money Fenghua special committee Secretary-General reported on the GB / T16508 since revised "shell boilers" start, the main author of each criterion according to the revised terms of reference and requirements, the completion of the GB / T16508-2013 "shell boilers" since the implementation of the views of summary each sub-standard and contrast "boiler rules" (issued), the sub-standard job descriptions revised terms.
GB / T16508 the sub-standard main author of this according to the relevant sub-standard content and "Boiler Rules" (draft for approval) comparing the results of the relevant sub-standard and harmonized need to modify the content of the standard version 13 implementation of the existing problems and proposed amendments analyze and explain proposed amendments focus on the sub-standard and major amendments envisaged.
Experts on key issues related to the sub-standard for the exchange and discussion to reach a consensus on major revisions of this standard and requirements.
Meeting according to GB / T16508 revision schedule requirements, arranged next phase of work, the following:
1. Revision of Standards fleshed out power to complete the Standards Working Group set up before the end of August;
2. Please carefully review the main author of each standard GB / T16508.1 ~ 16508.8 major amendments description, and recommend changes, submitted to the Shanghai International Industry pot special committee secretariat by August 25;
3.GB/T16508 the sub-standard main author collected the views, modify the preparation of the draft (draft) on the basis of the draft text, submitted to the Shanghai International Industry pot special committee secretariat on September 30.
At any time, domestic more and more attention to environmental protection, coal-fired steam energy saving coal fired dhl boiler suffered heavy damage. Relatively speaking, gas-fired steam boiler is favored by many users. In recent years, the state has also vigorously promoted the use of gas-fired boilers. What are the benefits of a coal-fired steam boiler? Let's discuss it with you today. Gas-fired steam boilers and coal-fired steam boilers occupy half of the market, showing a trend of court resistance, but in the long run, gas-fired steam boilers will obviously become the only dominant market. No, please look! 1. Procurement cost: it is clear that gas-fired boilers are well ahead of ignition in terms of technology and ancillary equipment The coal boiler is equipped with a special gas burner. Take 1 ton steam boiler as an example, gas-fired boiler is about 30% higher than coal-fired boiler. 2. Construction cost: this cost mainly comes from boiler room. Because of the coal-fired steam boiler supporting equipment more, boiler room construction should invest more funds. The auxiliary equipment of gas-fired boiler has few auxiliary equipment, automatic control operation, automatic alarm and automatic protection function, which not only saves the cost of building, but also is safe and reliable. After connecting the natural gas pipeline, the burner will automatically supply gas, which can effectively save staff costs. Coal-fired boilers also have to pay some of their employees' salaries because they need to participate in the coal program . 3. Fuel costs: you can see this clearly by looking at the actual specific fuel prices at each location. The fact is that the amount of coal burned per hour is much higher than the amount of gas. 4. Environmental costs: with the need to protect the environment, the audit of coal-fired boilers is becoming more and more stringent. Gas-fired steam boilers are more and more widely used due to economic operation, environmental protection and energy conservation, as well as government policies.
