The solid fuel fired and biomass fired boilers are mainly used in hotel, hospital, university, central heating, refineries, utilities, petrochemical, chemical, paper and pulp, steel and iron, food processing, power station, and other major processing industries. Solid fuel boiler is chain grate type boiler burning coal, biomass or mix-firing both. It adopts membrane water wall, with economizer in the rear of boiler. High combustion efficiency, energy saving and low emission. Three-pass tube design incorporating a wet back turnaround that eliminates the need for rear door refractory. Larger steam disengagement area providing high quality steam, larger steam storage capability for quicker response to sudden steam demand. Equipped with PLC-based control system to realize automatic operating in start-up, standby and shutdown control Designed, constructed and stamped in accordance with the requirements of the American Society of Mechanical Engineers.
Recently, the Tianjin Municipal Government issued the latest "2018 ~ 2019 autumn and winter tackling air pollution comprehensive management action plan" (the "Program"), "plan" put forward specific remediation requirements: the city's 65 steam tons / hour and above the basic realization of coal-fired boilers coal-fired power plant ultra-low emission standards, the development of energy-saving and ultra-low emissions rehabilitation programs for 65 steam tons / hour or more coal-fired boilers, the implementation started after the end of the heating season. Before the end of this year, within the city basically eliminated 35 tons of steam / h and coal-fired boilers of 25 iron and steel industrial enterprises discharge waste depths of governance, the basic completion of the iron and steel, building materials, thermal power, coking, casting and other key industries and coal-fired boiler fugitive emissions control.
"Plan" the implementation process to uphold the objectives warm winter and clean heating double standards, combined with the actual development of coal-fired boiler rehabilitation programs, to ensure completion before the end of the year 206,100 rural residents to use clean energy alternative to coal for combustion. Guidelines established after the first break, for the substitution of gas for coal to electricity instead of coal and other alternatives, in the case of gas supply, power supply is not implemented, the existing heating facilities will not be dismantled until the gas supply, power supply after the successful implementation be removed. And to develop high-pollution fuel combustion zone ban zoning adjustment programs, complete with electricity instead of coal, substitution of gas for coal in the region included the range of high-pollution fuel combustion zone ban. For failure to implement the heating area clean, good smokeless coal tender, production, supply, to ensure smokeless coal substitute the existing polluting large coal-fired boilers. Among them, before the heating period to complete large-scale centralized distribution, heating Doing the fragmented coal blending, before the end of December 2018, the actual realization of bulk coal dealers cleared.
What issues can explore the coal-fired biomass fired hot water boiler in north america? For this kind of boiler coal-fired hot water boiler, I believe we are not unfamiliar, because it is one of the site boiler products, so in front, has already begun work in this area of knowledge to explain, so that we have the learning content, thus come gradually, and as soon as possible to achieve this objective and comprehensive requirements. So, here is no exception, is on this kind of boiler, however, is something new to learn proceed. 1.1 tons of coal-fired hot water boiler 1 hour to 45 degrees how much hot water? This, then, depends on the basis of the boiler water temperature is. However, in general, if one ton boiler temperature is 40 degrees, then it on the water, it is generally within the range of 10-15 tons. Therefore, it should be clear. 2. In the coal-fired hot water boiler, whether it is the higher the pressure, the higher the temperature in the furnace, the faster the speed of the boiler water cycle? In addition, one ton of coal-fired hot water boiler, heating area can provide much? And, in the heating, boiler which we can use to achieve their goals? One problem, the answer is yes, but also know that, in the coal-fired hot water boiler, the higher the pressure, then, for boiler water circulation is better. But it is also a limit range. As for question two, the answer is 10,000 square meters of heating area. For the three, the answer is for the gas hot water boiler, oil hot water boilers, hot water boilers burning biomass, coal-fired hot water boilers, hot water boilers, etc. These and alcohol. 3. Thermal efficiency of coal-fired hot water boiler, what should you consider? For this coal-fired hot water boiler A boiler, in which the thermal efficiency, different manufacturers, which is somewhat different. As well as differences in the manufacturing process, but also lead to different thermal efficiency. In addition to these two, and method of operation, fuel type and the like, sometimes need to be taken into account. In general, which in normal circumstances, reaching over 90%, there is no problem.
How to choose a steam boiler heat exchanger? Steam boiler heat exchangers are generally divided into two categories, one is a direct contact heat exchanger, and the other is an indirect heat exchanger. 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. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass biomass fired hot water boiler in north america, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. They are used to recover flue gas heat, to achieve energy saving effect of the separation device. In general, conventional steam boiler can be increased by a simple transformation of energy-saving effects, such as increased waste heat recovery installation, which is energy-efficient steam boilers advantage. To promote energy saving is largely the cause of the country, to create more profits for the company, cost savings. Choose a good heat exchanger is one way to achieve energy efficiency goals. Direct contact heat exchanger is a steam boiler with heat recovery and a high ability to remove pollutants in flue gas, but acidic water quality, not easy to use in hot water heating boiler. The so-called indirect heat exchanger, thermal energy means that we recovered from the condensed-called flue gas. Today, more and more people choose to use the steam boiler, the proportion of the market is also increasing. Such steam boiler flue gas discharged contains a large amount of steam, by condensation and release large amounts of latent heat of vaporization. Coal-fired boiler efficiency is much higher than coal-fired boilers. This boiler has a good effect on the selection of the indirect heat exchanger.
