locomotive natural gas hot water fire tube boiler
So how versatile industrial locomotive hot water fire tube boilers for energy saving? First, the fuel added through the fuel economizer process various compounds economizer its internal molecular structure will produce changes in the viscosity of the fuel increases the distance between the molecules and the molecules decreases, complete combustion can be performed prior to refining to maximize atomization and so that combustion within the environment can be the most complete combustion, can reduce the heat from the flue more so that the temperature of the flue decreased. Added industrial boiler economizer and may eliminate the tar oil and the combustion secondary coking can be prevented, to prevent incomplete combustion of combustion leaving the furnace wall phenomenon, can achieve high energy saving effect. Second, add condensed industrial boiler economizer section at the time of exhaust of water vapor occurs, they can be utilized with great resistance, they can be fully utilized by the installation of the condensing economizer. Industrial boilers condensing economizer may be mounted through the flue of the boiler, it can effectively recover the energy available in the flue gas, the fuel is reduced defeating by condensation of water vapor in the flue gas absorption compound absorption, reduce pollution emissions have higher environmental awareness. Third, the exhaust heat recovery in high temperature industrial boilers, flue gas containing water vapor has been heat will be in state, not condense into a liquid flows out, part of the flue heat may be collected charged by the waste heat recovery apparatus again use, to maximize the energy use.
Technical characteristics: the overall cost of natural gas locomotive hot water fire tube boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.
According to statistics, Zhejiang Province, coal consumption totaled 145.91 million tons, accounting for 56.8% of primary energy consumption in the province. Although after careful environmental management, but the main coal-dominated energy consumption remains high in the province's total emissions of air pollutants. In the "Zhejiang Air Pollution Control Action Plan (2013-2017)" issued in December 2013, the coal-fired pollution control remains a top priority.
According to "Zhejiang low-carbon development" Thirteen Five "plan", as of 2020, the province's proportion of non-fossil energy sources will be increased to about 20%, the proportion of the total coal consumption should be reduced to around 42%.
June 15 this year, Hangzhou Iron and Steel Group ironworks blast furnace in the chimney successful blasting, declared the "three noes" no way to urban development of Hangzhou steel companies, no coal-fired generating units, there is no standard yellow car.
To control pollution from coal-fired source, Zhejiang Province, facing elimination from the transformation of the boiler parties policy, funding, pricing, comprehensive resources supporting the work in 2015, 2016, 2017 were given every right out of steam coal-fired boilers tons 15,000 yuan, 12,000 yuan and 10,000 yuan subsidy funds.
To eliminate 10 tons of steam / hour of coal-fired boilers, in October 2014, Zhuji City, party and government "leaders" personally took, within three months, through the introduction of reward and subsidy standards, regular assessment and other measures, the city's 1964 stage production behind coal-fired boiler demolition 1508 units, 390 units to natural gas or electricity, and the rest use biomass fuel, gas tank or centralized heating, completed the task of transformation. It is estimated that, this year more than 500 tons of sulfur dioxide emissions.
After a clear goal, the province's coal-fired boiler (kiln) transformation to accelerate out of the furnace. According to statistics, in the first half of this year, Zhejiang Province eliminate small coal-fired boilers 6200 Taiwan, has completed 77.5% of the annual task of eliminating.
How natural gas steam locomotive hot water fire tube boiler steam boiler model selection natural gas main type WNS and SZS type Both models can burn natural gas, liquefied petroleum gas, coal gas, coke oven gas, biogas, including steam boilers and hot water boilers, gas concrete how the selection of steam boilers, we take a look. Due to the different sectors of production processes, demand for steam boilers are also different, and therefore, when the gas steam boiler selection, need to have enough knowledge of the production process, in order to make the right selection and design of the boiler. 1, selection of technical parameters: gas comprising steam boiler rated evaporation, rated steam pressure, steam temperature rated, e.g., general pressure chemical production requirements are not too high, the pressure required to produce 10 kg as an example, then the boiler design pressure of 1.25 MPa is necessary to use; 2, ancillary equipment options: supporting auxiliary gas steam boiler main control cabinet, water supply pump, circulation pumps, burners, sub-cylinder, water treatment equipment, energy, a condenser, users can choose according to their own needs and price configuration; with the Earth's atmosphere deteriorating, I believe that we Chinese citizen environmental awareness is still very strong, in order to reduce pollution of the planet, we must first consider how environmentally friendly energy-saving performance, then consider fuel, gas boiler combustible gases, polluting emissions, environmentally friendly energy-saving ideas. Boiler pressures, consider the problems caused by an explosion caused by overpressure, and even carbon dioxide poisoning incidents. In the control of gas-fired boiler operation, select the better it is simple and easy to operate.
