Steam boiler fuel gas composition changes so the General Assembly cause flameout: fuel gas fired steam boiler hotel pressure off the fire caused by a sudden rise, the solenoid valve malfunction the gas supply interruption, the gas composition has changed so much moisture content is too high and so on. Blower, fan failure, the load is too low furnace pressure is too large excessive leakage and other excessive wind, so that the furnace temperature is too low can also cause steam boiler fuel flame. Causes fuel steam boiler flameout are: oil pump failure, the oil surface is exposed inhalation tube, clogging of the oil filter or oil supply pipe, a solenoid valve malfunction or misoperation caused by oil running intermittently. During transport the fuel with steam by heating water; inappropriate position inhalation tube with the pumping of water; improper contaminated oil floating on the water; poor dewatering tank drain plug such that the fuel with water.
Boiler and fired steam boiler hotel comparison on the specific types of boilers, the following will be involved for the boiler this specific type of boiler. Moreover, because it is widely used, as well as website products and keywords, it is necessary to have an in-depth and comprehensive understanding so that it does not miss any of its knowledge points, and at the same time, it can also make the product have a good use effect, So that we can benefit from it. 1. Are boilers and steam boilers comparable? Boilers and steam boilers, these are two specific types of boilers, but from a professional point of view, these are two completely different kinds of boilers, although they are both large in the boiler. Class. Therefore, the boiler and steam boiler are not comparable, and are not suitable for comparison, because the comparison is of little significance and value. 2. What should be the choice of the high temperature used in the boiler? The high temperature used by the boiler shall be selected according to the grades and requirements of the heat use process, and the high temperatures of all grades shall be correctly selected, and the requirements of the Standard of Safety Technical Supervision for Organic Heat Carrier Furnaces shall be strictly complied with. So that they can be used correctly. 3. Is there a difference between the heater and the boiler? Heaters and boilers, though similar in name, are two different things. Because, Heaters are heated with resistance, while boilers use fuel, such as coal and natural gas, to provide heat. In addition, they are also very different in the use of oil.
What impact have fuel moisture fired steam boiler hotel? Most of the aqueous fuel when coal or heavy oil with steam atomization of entrained moisture in an amount not more than 5%, no effect on the coil and the inner shell boiler, the boiler because their materials are steel, steel are mainly: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng, with a strong antioxidant, water resistance. With more moisture, combustion performance worse, if the moisture up to 40% burn will be extinguished.
Hefei is the blue sky to win the Battle of key areas for innovation to create an international influence is of great significance. Is determined to win the battle of the blue sky, the city combined with the actual situation, formulate a three-year action plan to win the embodiment Battle of blue sky. Details are as follows.
I. Target: 2020, sulfur dioxide, total nitrogen oxide emissions were reduced over 23.1% in 2015, more than 24.2%; PM2.5 concentration decreased more than 18% in 2015, the ratio of the number of days air quality assessment requirements up to the national , severe pollution and over several days ratio decreased by more than 25% compared with 2015; the full realization of "thirteen five" binding targets.
Second, the continued implementation of the total coal consumption control. By 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's total coal consumption to complete the tasks assigned by the national and provincial; new coal projects to implement the reduction of coal instead.
The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement may be within the total national and provincial construction plan developed according to the control range, co-ordinate arrangements for the construction of ultra-low emission coal-fired capacity unit.
Third, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, ceramic, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry characteristics can actively promote industrial production, building heating and cooling, transportation, agricultural production, the implementation of the residents living in five major areas "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for. Of the new "coal to gas" projects, we should adhere to increase coal gas reduction to gas will change under the premise signed gas supply contracts, orderly implementation.
Fourth, to carry out comprehensive improvement of coal-fired boilers, coal-fired boilers to increase efforts to eliminate, consolidate the results of coal-fired boilers eliminated. Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation, one by one registration. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour and coal-fired boiler above (except boilers fired power plant) all meet special requirements emission limits; allowed to remain 65 tons of steam per hour coal-fired boiler and above all the complete energy transformation and ultra-low emissions within the city. County (city) district, zone one by one before the end of June 2019 to develop low-nitrogen combustion rehabilitation programs for existing gas boiler, complete combustion of low nitrogen transformation in this area of existing gas boiler before the end of 2019 more than 50%, before the end of 2020 transformation is substantially complete; after transformation principle NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. Urban built-up area of ultra-low emission biomass boilers implement reform.Free Chat
