To continue to improve urban air quality, to ensure the safety of winter heating, heating Dalian Municipal Construction Committee Office will strictly enforce the "Clean northern winter heating plan (2017-2021 years)" (the "Plan"), and strive to achieve clean heating.
"Plan" put forward, Dalian will gradually increase clean heating rate, adhere to clean coal-fired central heating, local conditions of use of electricity, natural gas, solar energy (3.250,0.04,1.25%), biomass and other clean energy heating, heat storage are encouraged to promote electric heating type and other ways; the existing thermal power plant, waste heat of industrial enterprises depth potential, priority use of heat source heating to achieve ultra-low emissions; research to develop clean energy heating pricing policies; supporting natural gas pipeline network to speed up urban construction, in the implementation of the gas source, guarantee under the premise of residents to use gas, natural gas heating in an orderly way.
Continue to optimize heat distribution. Speed up the construction of heating pipe network, out of network coverage and bulk coal fired boilers within range. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume.
2018, the city built-up area basically integrated heating. 2019, the county level and above the basic integration of urban built-up area of heating. Before the end of 2020, according to the special plan for urban heating requirements, the county level and above in urban built-up area within the range of 300,000 kilowatts and heating cogeneration power plant over a radius of 15 kilometers, coal-fired boiler and does not meet the ultra-low emissions of coal-fired power plants all closed down integration.
2018, above the level of removal of industrial parks and 10 tons of small coal-fired boilers 49 units, 265 units and 10 tons of banned coal-fired boilers since 2014, new registrations. 2019, to improve the standard phase-out of coal-fired boiler, expand the scope to promote the elimination of urban built-up area of 20 steam tons / hour (or 14 MW) and coal-fired boilers. 2020, except in accordance with urban heating heating boiler special plans need to retain outside built-up areas at the county level and above cities 20 steam tons / hour (or 14 MW) and coal-fired boilers to be eliminated.
Gradual development of ultra-low emission ultra-low emission coal-fired power plant renovation, started in 2018 and the North Sea thermoelectric thermoelectric Taishan ultra-low emissions renovation, completed in 2019 Heung Hoi coal-fired thermoelectric power plants and other enterprises reform, in 2020 to complete a full ultra-low emission coal-fired plant transformation .
CFB boiler can be divided into coal fired boiler and biomass fired boiler according the cumbustion fuel.ZG can design and supply CFB steam boiler,CFB automatic control biomass pellet hot water boiler agent and CFB power plant boiler.The capacity of CFB steam boiler is 10-280ton,CFB hot water boiler is 20-160ton,CFB power plant boiler is 10-50MW.All these three types boiler play a vital role in industry.
1.3 ton biomass steam boiler in Sri Lanka have advanced three pass wet back design:adopts the most sophisticated three returns all wet back structure,thread smoke tube structure, weld joint with high quality.
2.3 ton biomass steam boiler in Sri Lanka with advanced manufacturing equipment endows Safe and reliable property:adopts corrugated furnace lamps, multi-chain protection. Water level, steam pressure, gas pressure protection. And before leaving factory, all the boiler have been rigorous inspection and testing, including pressure tests and X-ray detection.
3.3 ton biomass steam boiler in Sri Lanka have large boiler proper heating area:adopts unique design of a large combustion chamber which increases the radiation heating furnace area, reducing the size of the boiler, reducing the NOX emissions.
Steam boiler preventive measures introduced Common Failures and precautions steam boiler and steam reciprocating pump 1. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass automatic control biomass pellet hot water boiler agent, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Near the steam boiler room should be equipped with adequate and effective fire fighting equipment. 2. Steam boiler room must have staff on duty 24 hours, the guards take turns, and always check the water level in the boiler, in order to ensure that it is above the safety line to prevent an explosion caused by burning dry. If the fire operation in explosive areas must obtain a work permit fire and take adequate fire safety measures in order to carry out fire work. When the fire should send someone on duty at all times observe the fire situation. 3. A storage vessel containing the non-flammable gas in the boiler room. 4. The staff of steam boiler room must be certified before the arrival of the boiler and proficient technique, it has a certain capacity to detect and recognize security risks. 5. If the boiler safety on a regular basis in accordance with the boiler maintenance procedures, should be carefully examine each of insecurity in the inspection process. 6. Distribution Line steam boiler room disposed defective safety device using a metal tube or pipe nonflammable hard plastic protection switch box should be installed outside the boiler room, respectively, to achieve power, should be prohibited. 1. What is the reason there is no discharge of steam reciprocating pump is? How, how? A: (1) Failure: 1 suction or discharge pipe blockage. (2) out of the stuck valve. There is an air cylinder. (4) a suction tube connected lax. (5) column (live) seriously damaged piston ring. (2) Method excluded: (1) exclusion of pipe blockage. (2) Remove the inlet, the outlet valve on the plug. (3) filled with water, the air is discharged. (4) fastening the pipe. (5) Replace Column (live) piston ring.
