cheap price hot water boiler for selling used in hotels

Industrial plant boiler cleaning method which: industrial plant boiler cleaning method What? For industrial boiler plant, the run for some time are to work descaling, if not timely cleaning, for normal operation of the industrial boilers, will have a great impact. Clear boiler scale methods, mainly mechanical descaling and chemical descaling two kinds. Mechanical descaling by the people directly into the drum, spatula or heating surface cleaner to remove scale. However, this method is labor intensive, easily damaged heat transfer surface roughness increases heat transfer surface, not completely clear, it has been rarely used.

In our products lists, DHL biomass fired boiler adopts two patents from Xi’an Jiaotong University one is Flying ash re-combustion equipment based on the high temperature separation and the other is Combined uniform flow design technique of comer tubes boiler flag pattern surface. The two patents can ensure our DHL boiler automatic and fine working condition. Besides, in this DHL boiler, the cross-girder grate is adopted, so it has the features of less operation resistance, better grate cooling effects, lower breakdown rate, less fuel leak. And the grates are made by the first-class professional manufacture. The boiler adopts two times turbulence combustion design technique and flying dust high temperature separation plus flying dust inner circulating fluidized re-combustion.

To speed up solving air pollution prevention and control Liaoyang key and difficult issues, Liaoyang city government combined with the actual circumstances of the sky to win the Battle of implementation. Details are as follows.

1, promote clean heating. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. In strict accordance with the "Notice on and of" (Municipal Office Liao Fa [2018] 19) requirements, minutes from the town to the countryside level steady implementation of clean coal-fired heating, natural gas heating in an orderly way, actively promote electric heating, heat pump heating scientific development, expansion of industrial waste heat heating, heating to accelerate improvements in the proportion of clean, implement the relevant provincial price policy, ensure the power supply. 2019 Clean heating rate should reach 44% in 2020 to clean the heating rate should reach 49%.

2, control total coal consumption. According to energy-saving emission reduction Work Leading Group Office of the City "on the issuance of Liaoyang control total coal consumption program of work (2018-2020 years)" (City of Liaoning Office Savings Fa [2018] No. 3), the city's total coal consumption do control. Vigorously for shutting down energy consumption, safety, environmental protection and other 300,000 kilowatts coal-fired units of non-compliance, capacity indicators for shutting down the unit, allowing the transaction or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. In 2020, the city's coal accounts for the proportion of total energy consumption control to 58.6% or less.

3, in-depth implementation of coal-fired boiler control. Increase the small coal-fired boilers (including coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities) elimination efforts. According to the principle of small demolition and Japan to promote clean energy use, developing the approach to co-ordinate the establishment and management of inventory ledger. Strengthen ecological environment, housing and urban construction, industry and information technology, market regulators linkage, strictly control new coal-fired boilers. 2018, 10 steam tons / hour (or 7 MW) coal-fired boilers and focus on the completion of the phase-out of county level and above all the urban area and old inefficient coal-fired boilers small tasks within the industrial park, small demolition boiler mission of 111; 2019, to phase out coal-fired boilers to further improve standards, expand the scope to promote the elimination of urban built-up area of ​​20 steam tons / hour (or 14 MW) and coal-fired boilers, in addition to special planning according to urban heating heating boilers other than essential to retain, urban built-up area 20 steam tons / hour (or 14 MW) coal-fired boilers to be eliminated and all.

4, the development of industrial furnaces governance special action. Development of industrial furnace remediation plan to carry out an intensive investigation, the establishment of various types of industrial furnaces inventory management. Increase the non-compliance of industrial furnaces out of efforts to speed up the elimination of small and medium gas furnace. Encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Key areas banned fired stove, the coal-fired cogeneration substantially eliminated heating pipe network coverage heated oven (furnace); out hearth diameter of 3 meters fuels gas furnace, a fixed bed to increase fertilizer industry intermittent coal gasifier reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke. The industrial furnace governance as key tasks of environmental inspectors, who have not included in the list of industrial furnaces were included in the autumn-winter peak load shifting production program.

In the past few years, several large-size CFB plant boilers (over 100 MWe) have entered service and are operating successfully. On the basis of this experience,CFB boilers up to 400 MWe in size are now being offered with full commercial guarantees.Such large CFB boilers will be of interest to countries with strict emission regulations or the need to reduce emissions, and to countries with both a large need for additional power and low grade indigenous solid fuel.
