solid fuel boiler industrial small gas fired boilers
Dongying City, Shandong Province in response to low-nitrogen coal-fired solid fuel boiler industrial small fired boilerss, industrial waste heat recycling and other environmental policies, combined with local conditions, Dali urban and rural areas to promote clean heating projects, and achieved remarkable results. As of mid-October this year, Dongying City clean heating rate of more than 72%.
Recently, Dongying Municipal Urban Management Bureau to the outside world, in order to further promote the urban and rural clean heating, it has already shut down 10 coal-fired boilers environmental non-compliance of a total of 155MW.
After shutting down 10 coal-fired boilers environmental non-compliance, Dongying City high environmental standards were established in a total of four 58MW gas-fired boiler and a total of four 70MW coal-water slurry boiler through a series of energy-saving treatment, flue gas emissions much higher than the index of new environmentally friendly ultra-low emission requirements.
Meanwhile, Dongying City, the original heating effect is also unsatisfactory 4.33 million square meters of heating regions to establish a uniform heating systems, and the use of standards to ensure clean heat source; higher operating costs for the original 2.17 million square meters of heating area heat source replacement process, both to ensure good heating effect but also saves a lot of money.
According to statistics, this year the city of Dongying city plans to add a total area of clean warm 8.1138 million square meters, down to the next new clean heating in rural areas 45000.
Recently, Dongying City issued a "Dongying City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), after the completion of the city's 10 steam tons / hour and small coal-fired boilers zero and start steaming for 35 out of work t / h coal-fired boilers and, as of 2020, out of 35 steam tons / hour and coal-fired boilers.
On a more specific type of a gas solid fuel boiler industrial small fired boilers steam boiler steam boiler and comparison of gas steam boiler and steam boiler, the following will be involved, for this specific kind of gas steam boiler furnace. Moreover, since it has a wide range of applications, and is the product website and keywords, so it is necessary to conduct in-depth and comprehensive understanding, so as to not miss any of its knowledge, and at the same time, but also allows the product to have good results, let us benefit from it. 1. Gas steam boiler and steam boilers, whether they comparable? Gas steam boiler and steam boilers, which are two specific types of boilers, however, from a professional point of view, these are two completely different boilers, although all in the boiler in this category. Therefore, gas steam boiler and steam boilers are not comparable, not suitable for comparison, because then no significance and value comparison. 2. The high-temperature gas-steam steam oven gas used, what to choose should be based on? High-temperature gas-steam oven gas and steam is used, it should be selected based on grades and hot gas-steam process requirements, and that should be the right choice for a variety of high-temperature gas-steam grades and strictly comply with the requirements "organic heat carrier furnace technology to monitor the safety regulations" this standard in order to achieve the proper use of gas steam. 3. gas steam heater and gas steam boiler, Is there a difference? Gas steam heater and gas steam boiler, although the two are similar in name photogenic, however, are two different things. Because, gas steam heater is a resistance heating gas with steam, and the steam boiler is the use of gas fuels, such as coal and natural gas to provide heat these. In addition, they use in the oil, but also very different.
Where gas solid fuel boiler industrial small fired boilers Fortunately, than coal-fired boilers? While some provinces there is a problem of gas shortage, but to understand China's current gas pipeline network construction planning of people are not too worried, after all, "less gas" is our long-term lack of reserves caused only boiler from coal to gas pushed forward one only. For customers not to buy gas boiler, may consider other clean energy boiler equipment, such as gas boilers, boiler methanol, biomass boilers, etc., there is something to meet demand; customers only purchase natural gas boiler, if production applications, the current provinces have issued relevant policies, "Paul production" is one of the measures the country, it can only be supplied only for heating.
Boiler precipitator technical principles of environmental protection and the development trend in recent years, the rapid development of gas power plant solid fuel boiler industrial small fired boilers in the direction of large-capacity, high-parameter, either manufacturing or operations management have been close to the advanced level. Boiler and gas industry to maintain large, widely distributed, high energy consumption, heavy pollution, energy efficiency and pollution control the overall level compared with foreign countries have a certain gap, a huge energy saving potential. By the end of 2012, China's use of gas in industrial boilers 467 000 units, with a total capacity of 1.78 million tons of steam, the annual consumption of about 700 million tons of coal, accounting for over 18% of the country's total coal consumption. China's gas lower overall energy efficiency of industrial boilers, about 15 percent of its actual operating efficiency lower than the international advanced level, with great potential for energy savings. In recent years the rapid development of technology the dust bag, in particular accessory bag filter (dust bag, dust bag cage pulse valve, control of the PLC technology, etc.) to improve quickly, while baghouse 10% desulfurization efficiency can be improved It is dry boiler flue gas desulfurization one of the major thermal power plant equipment. Boiler precipitator dust is the most effective pollution control equipment. It has a high dust removal efficiency, after the flue gas-containing filter baghouse dust concentrations below 50mg / m3, even at 10mg / m3 or less, and can efficiently remove the fine dust particles. Boiler boiler precipitator not just in the production of which use can also be used in other fields of thermal power. During use of the boiler generating the flue gas and dust is inevitable, the boiler boiler precipitator dust is separated out from the flue gas, thus reducing the dust pollution and facilitate further flue gas desulfurization, denitrification process. Spark arrestor smoke dust is mainly used in some high temperature and flue gas containing process Mars. For example, the flue gas cupola, intermediate frequency furnace flue gas, a furnace flue gas and so on. The main role is to eliminate smoke sparks, to avoid burning dust bag. Spark arrestor has a variety of structural forms, cyclone, louvered like. The most effective way of collecting cyclone is, the guide vanes guide the flue gas using a cyclone-type rotational flow, after the dust and large particles Mars cylindrical guide vane duct wall collision or off. When the smelting furnace flue gas containing spark large particles, dust bag will cause damage. Mars trap can effectively trap particles Mars in the flue gas, the protection of the bag filter. The entire device by the PLC control unit, automatic cleaning, discharging and automatic temperature control and over-temperature announcer.
