Fire tube or “fire in tube” boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Oil fired fire tube wet back structure steam boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5kg/cm2.
Luzhou, Sichuan issued a notice to win the Battle of Blue Sky embodiment. Program requirements, to promote ultra-low emissions to upgrade the steel and cement industries, and increase efforts to eliminate small coal-fired boilers, phasing out the whole 10 tons / hour and below the coal-fired boilers. Details are as follows.
1, to accelerate the development of clean energy. Scientific and orderly promote clean energy development and utilization of hydropower, natural gas (shale gas), wind power, solar, biomass and so on. By 2020, the city's total primary energy consumption of 12.48 million tons of standard coal, total coal consumption control in less than 6.5 million tons, accounting for the proportion of total energy consumption control in less than 42%, the newly constructed and put into operation a large municipal solid waste incineration power plants, garbage power generation capacity of 12MW, a new wind farm installed capacity of 48MW, the development of distributed PV installed capacity of 5MW, the new large biogas 5. Improve the construction of reservoirs for natural gas production and marketing system.
2, to promote the use of clean coal. Efforts to increase coal washing, coal simultaneous construction of new coal washing facilities, supporting the completion of existing coal mines coal washing facilities in accordance with points Area. Improve coal quality and use of standard industrial, commercial coal do not comply with environmental standards required by regulations of coal quality merchandise. Prohibit the circulation and use of low-grade bulk coal, bulk coal investigated and dealt with according to the law without a license behavior. Increase the civil bulk coal clean governance efforts to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves, strengthen civil bulk coal management. Strengthen regulation and control coal use in autumn and winter.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. By 2020, the county level and above cities phasing out the built-up area per hour and 10 tons of steam coal-fired boilers, in principle, to a new 35 tons of steam per hour of coal-fired boilers, in principle, to other parts of the new 10 per hour tons of steam coal-fired boilers. Ambient air quality standards are not areas should further increase efforts to eliminate.
4, increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network and bulk coal fired boilers within the coverage area. In areas not have cogeneration district heating conditions, a plurality of existing coal-fired boilers of small, actively promote the implementation alternative energy.
What are the advantages condensing boiler condensing boiler is now gradually into the public view, many people are not very understanding of condensing boilers, to choose whether you want to condensing boiler factory direct supply more hesitant. In fact, the condensing boiler uses a new technology, which is condensing technology, condensing boiler and combustion principle premix combustion air and gas mixing ratio in accordance with the best combustion efficiency is improved. Then we will introduce condensing boilers What are the advantages: 1. modular division, convenient: a whole will follow the rules of the boiler is divided into many small boiler, which is the boiler module. It can be said boiler module by the number of "parallel combination of a simple" scale can be achieved in any single boiler, and a portion of the system maintenance costs, may reduce the boiler room (including soft water preparation system, automatic control system, a gas system, etc.) is equivalent to smart unattended, can effectively reduce the cost of management and staff. Most people should have understood them in modern management, a key factor affecting the overall cost is the output of labor costs, so consumers in the use of condensing boilers, than using conventional boilers save most of the money. 2. low load, high efficiency: the smaller the output load due to the condensing boiler, the higher the efficiency of its operation; the lower the contrary. Therefore, high efficiency condensing boiler is running at low load, just to meet summer demand, and higher annual average efficiency not only saves energy consumption, but also reduces the cost of running late. 3. The premix combustion system: combustion efficiency depends on the mixing ratio of gas and air and a combustor, the condensing boiler technology stepless fan, according to the load demand, stepless adjustment of air quantity; while adjusting the gas condensing boiler technology by adjusting the ratio volume, both remain at the optimum mixture ratio, to ensure complete combustion. Unique water-cooled burners, the flame temperature is rapidly lowered, improve the combustion efficiency while ensuring low emissions of harmful substances. From the advantages of condensing boilers above three aspects, factory direct sales of condensing boilers can provide more heat in the boiler on the same fuel consumption, but also has a condensing boiler environmental protection, energy conservation, safety of many advantages, but in today's resources so tight under the situation, the condensing boiler will come out on top in the market.
Coffee grounds CFB boiler is very popular due to their low cost on fuel material-coffee residual. Coffee grounds CFB boiler is one of biomass boiler types. Today, we will mainly talking about coffee grounds fired circulating fluidised boiler as follows.
The wet back boiler design uses separate tube sheets between tube passes which can be more forgiving with load changes. Wetback firetube boilers offer a more optimal functional footprint, with lift off or split-hinged doors that require no cool-down period and can be opened immediately.Online chat
