horizontal oil gas fired hot water boiler

Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast boiler. Thus, when the company in the purchase of the product boiler, and fast boiler almost hit it off, by the party to provide a fast 6 tons of steam integrally condensing gas steam boiler (WNS6-1.25.Y.Q).

Different natural gas steam boiler energy-saving measures as well as gas-fired boiler with environmental issues become more critical, more and more people are concerned about the importance of the environment for our development. Today, gas steam boilers in industrial production is very common, how to reduce the energy consumption of gas steam boilers, which we have been explored. We can take the following measures in natural gas steam boiler operation for energy. 1, the amount of steam needed for industrial production of a reasonable choice, and the number of the rated power station boiler steam boiler gas, in both cases the higher the degree of matching with the actual exhaust gas loss is smaller, the obvious energy saving. 2, the fuel in contact with air: fuel amount so that an appropriate amount of air and the optimum composition ratio of combustion, this would both improve fuel combustion efficiency and reducing emissions of polluting gases, energy to achieve the dual goals. 3, reducing the temperature of the exhaust gas steam boiler: the temperature of the boiler flue gas to reduce the effective use of exhaust heat generated in general, the efficiency of the boiler used is 85-88%, the exhaust gas temperature is 220-230 ℃. If the setting of energy-using the exhaust heat or the like, the exhaust gas temperature falls to 140-150 deg.] C, the boiler efficiency can be increased to 90-93%. 4, recycle heat from the boiler blowdown water: water using continuous blowdown heat by heat exchange, in addition to improving water temperature itching water to achieve energy saving gas steam boiler. At the same time, measures energy-saving gas steam boiler can also be reasonably recovered condensate heating system, and the heat of the condensate water recycling. It is different from the gas boiler and gas boiler: 1. Gas circulating fluidized bed combustion boiler coal by crushing device by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx discharged from the flue gas the atmosphere, pollute the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions relative gas boiler gas boiler, SO3, NOx is much less. 3. Usually ventilation negative pressure combustion gas boiler, the combustion process is to group together to complete the mating with the mating blower and induced draft fan, the coal combustion process, requires a lot of air and the furnace wall due to the leakage of the flue, the excess air coefficient of up to between 2.1-2.5. Gas boiler combustion slightly positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion flue and the furnace wall, the flue outlet air ratio operation may 1.05-1.2.4. Fuel explosive gas boiler combustion safety, the furnace explosion hazard unlikely to occur. The gas-fired boiler in the explosive concentration limits encountered fire will explode. More dangerous. 5. Gas boiler control difficult due to coal boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to the operating parameters of the boiler load is large. Less impact on the factors of the gas boiler, the burner may be adjusted according to the size of the load valve, easy to achieve automatic control.

If within the natural gas boiler wear how to do? Off If there is detailed examination within the natural gas boiler wear how to do? Detailed examination is the key, fuel management is equally important. According to health and time natural gas boiler, we can plan a reasonable wear health check. When using the fuel, we strictly control the particle size of coal and limestone. Should strictly control the size of the bed material. Boiler waste should be handled. Boiler slag to be treated before discharge. Natural gas boiler should be installed in the heat of use, ease of installation. Hot water pipes should not be too long. It should have a good insulating layer. Hot water output to the end of the pipe should be suitably inclined. A water supply source should be equipped with a control valve. Of emissions, natural gas boiler chimney should extend to the outside, the outlet should be higher than the boiler 1.5 to 2M. If you want to reduce the impact on water wall tube, air pressure and air volume can be adjusted appropriately, effectively reduce the wear and tear of the water wall. Check the standby time is generally down or stop. To check items include leak wear, sealing the furnace and the furnace wall of smoke. In the event of wear, the need for timely repair and welding, to ensure the normal operation of the steam boiler. In general, before the gas-fired combustion of fossil fuels need to be filled in the combustion chamber, fossil fuel and bed material and recyclable materials in air speed, strength and stiffness of the shed fully integrated. Wind bottom means upwardly within the core region. Movement of the outer annular region of downwardly along the walls of the flow of boiler water, thereby prolonging the residence time of the coal particles in the furnace. Mineral particles, large amounts of ash and flue gas contains large amounts of fly ash particles, which continue to cause rapid wear of the water wall tube, wall thickness wear thin, resulting in wear and tear.

Oil-fired boiler technical analysis when equal sulfur content greater body oil and coal, low-temperature corrosion of boiler fuel in general is much more serious than a coal-fired boiler, for two main reasons: 1 coal-fired boilers, especially pulverized coal, coal 90% of the ash content of the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed fly ash in the flue gas, sulfuric acid vapor in the flue gas is reduced; coal combustion, about half of the sulfur remaining in the ash . While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content in the fuel, about 11% to 12%, per ton of fuel combustion can produce about one ton of water vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because with water and more exceptions detailed in Table 1 below. When these two reasons that the fuel, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to use of fuel oil-fired boiler, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, low-temperature corrosion is worse than boiler fuel fired boilers.
