specifications of electric water boiler

Function of different types of gas boiler is not the same for each fuel boilers are not the same, with some coal to burn, some with gas or fuel oil to burn, but also some combustion power, as well as the use of coal-water as a raw material slurry of combustion. Some gas boiler is also been called a gas furnace. This is generally used for boiler fuel, but fuel is also classified, some heavy, some light oil. If the raw materials are burning gas, then this can also be classified, some inside the city gas use, there is natural gas. Burning hot water boiler to heat water to a boil, whether kerosene or gas as raw material are possible. The use of gas to boil water in the boiler, use gas to heat water in the boiler, use gas to generate steam boiler works, etc. belong to this series of boiler gas boiler. Use hot water boilers to burn gas, it has a name, that is the use of gas to provide heating boiler, there is the use of the gas boiler can boil water and take a bath. This boiler can be inferred from the name on it out of the raw materials used are burning gas. In use among gas boiler and boiler fuel use and the use of electric power boiler combustion, they are more affordable economy. But the most inexpensive gas boiler or the use, of course, this is the choice of many people. Gas-fired boiler is very common in daily life, a lot of heating, bath facilities are of this boiler. The benefits of using gas to boil water can be more, not only a short time to boil water, and gas usage is not too much, so that more of the cost.

There are two methods to calculate the furnace structure characteristics of an electric boiler: first, when designing a new electric boiler, according to the combustion requirements, according to the selected thermal strength of the grate area and the thermal intensity of the furnace volume, the area of the discharging row and the primary determination of the volume of the furnace are determined. And structural dimensions. Second, preliminary determination of the grate area and furnace volume according to the boiler recommended estimation method. In order to calculate the characteristics of furnace structure, the radiative heating surface of furnace should be arranged according to the requirement of heat transfer, and the layout sketch of furnace structure should be drawn up in order to calculate the characteristics of furnace structure. When checking the furnace of the existing electric boiler, if the structure is known, the characteristics of the furnace mechanism should also be calculated. Calculation of furnace structure characteristics of electric boiler Provide necessary mechanism data for furnace heat transfer calculation. If the flue gas temperature at the outlet of the furnace is not reasonable after heat transfer calculation in the furnace, the arrangement of the furnace mechanism and radiation heating surface should be modified, and then the calculation should be carried out. The perimeter of the furnace volume of the electric boiler is: the surrounding area and the center line of the water wall on the top of the furnace. (if the water wall tube is covered with fireproof coated active refractory brick, it is the facing surface of the wall. The place where the water wall is not laid out is the inner wall of the furnace wall. The exit window is the surface of the front-most row of pipe centerlines) and the bottom. When hydraulic oil flows through all kinds of hydraulic valves, there is inevitably pressure loss and flow loss, which is the energy of this part. Loss accounts for a large proportion of the total energy loss. Therefore, choosing the hydraulic pressure reasonably and adjusting the pressure of the pressure valve is also an important aspect of reducing the power loss. The flow valve is selected according to the range of flow regulation in the system to ensure that its minimum steady flow rate can meet the service requirements. The pressure of the pressure valve is as low as possible under the condition that the pressure of the pressure valve meets the normal operation of the hydraulic equipment. Reasonable selection of hydraulic oil. When the hydraulic oil flows in the pipeline, it will show viscosity, and when the viscosity is too high, it will produce a greater internal friction force, which will cause the oil to heat up, and at the same time increase the resistance of the oil flow. When viscosity is too low, easy to cause leakage, will reduce the system Volume efficiency, therefore, generally choose a suitable viscosity and good viscosity-temperature characteristics of the oil. In addition, when the oil flows in the pipeline, there is also pressure loss along the path and local pressure loss, so when designing the pipeline, it is possible to shorten the pipeline and reduce the bend at the same time.

609, why the steam boiler is replaced by electric heating gas steam boiler steam boiler is replaced why the electric heating gas furnace compared with the steam boiler steam, and the higher production requirements, pressure increases with increasing temperature. In recent years, new thermoelectric organic heat transfer oil furnace is also known as heat transfer oil furnace. we usually referred to as gas steam heater. it combustible gas and electrical energy to thermal conduction of the heat medium oil high oil outlet to 400c, heat device connected to the hot water more environmentally friendly and energy saving compared with the steam boiler, saving up to 40% to 55% oil furnace using electric heating and the conductive loop. different steam, the steam is directly discharged after use, heat can not be recovered heating stable, accurate temperature control. gas steam boiler and the heat transfer pipe are stable, unlike a steam boiler steam temperature fluctuations in the system, gas and steam electric furnace facilitate automatic control microcomputer electric heating oil heater low and high temperatures are secure, gas and steam heated to 340 degrees at normal pressure, does not evaporate. steam reach the same temperature, the saturation pressure 14.593MPa. hot water boiler must be in order to achieve a certain pressure High water temperature. If you want to get a temperature of 280 degrees Celsius, the pressure should be reached 6.412MPa. Therefore, gas steam heater has a good safety performance heat transfer oil furnace electric heating with low cost, low investment, easy to manufacture and so on. due to the low heat transfer oil furnace operating pressures, significantly easier to manufacture than the steam boilers and hot water boilers, low cost, small investment. in general, class E with twelve kinds of boiler or pressure vessel manufactured qualified manufacturers have the ability to produce hot oil furnace .609,
