3, water tube low pressure fried hot water boiler fuel

As the name suggests, fuel oil hot water boiler is fuel, including diesel fuel, motor oil, kerosene and other types of fuel. In many areas, higher electricity prices, natural gas is more troublesome, oil is a good choice.

Structure and characteristics of Water Tube Boiler (double Longitudinal Tube Boiler)

The structure of the double vertical tube water tube boiler is mainly composed of upper and lower vertical tube, convection tube bundle, water wall tube, header box and down tube and other pressure-receiving components. The length of the lower drum is about half shorter than that of the upper drum. The empty space is provided with a furnace, a curved water pipe is arranged between the two drums, and a water wall tube is arranged around the furnace. The burning equipment adopts a gas/oil burner, and the tail flue has an economizer. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa). The high-temperature flue gas enters the rear convection flue from the right exit of the furnace, flows in an S shape along the two smoke-proof walls, flushes the convection tube bundle laterally, and then flows through the economizer from the left side of the furnace wall, and is discharged by the induced draft fan and the chimney.

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.

Our hospital requirements for environmental protection, health and safety in these areas is very high, for a wide variety of market boiler is also very headache and confusion, there fast boiler solve the above problem, the boiler set clean environment to provide for our hospitals and efficient operation in one, coincides with the philosophy of our hospital. --customer feedback
