efficient 5000 kg electric steam boiler
Steam boilers for industrial production of stable and high-quality delivery of steam, wide range of applications. Depending on the fuel, coal-fired boilers can be divided, biomass boilers, gas-fired, oil-fired boiler and an electric boiler.
Hot water boiler water filling boiler considerations and parameters between boiler pressure hot water boiler of this kind in which the boiler is a common and frequently used species, but also in terms of all of us, need to have a comprehensive knowledge and understanding, because the only way to be correct and rational use of hot water boilers and have good results, but also to avoid misuse and adverse impact. 1. boiler parameters, whether on the same hot water boiler and steam boiler? From a professional point of view, the parameters of hot water boilers and steam boilers are not exactly the same, there are some differences, because the parameters of the boiler steam boiler steam boiler is concerned is the number of generated operating pressure and temperature steam, hot water thermal power boiler in terms refers to the boiler, the water supply and return water pressure and temperature. In addition, its different parameters, it corresponds to the unit is not the same. 2. Boiler Feed water pressure Cautions Boiler Feed pressure hot water process, there are some considerations, which is specifically as follows: (1) Sheung boiler heating system should be carried out separately, can not be together, because the boiler when you stop running between the boiler and the system is cut off. At the operational level, is you want to Sheung Shui to low water boiler expansion tank, then the system can Sheung Shui. Water Supply System, which can be used to perform Sheung pressure of the water filling the water system, if the pressure is less than water, circulating pumps can be used for water filling system. (2) If the system is filled with water by the circulation pump, which is specific to the operation: the boiler return pipe inlet valve is closed and the circulating pump will be multiplexed into the water pressure in the system until the system after the completion of charging water, then adjust the water level in the boiler. Meanwhile, while the system is filled with water, to be noted that the exhaust gas system. 3.1.4MV electric heating hot water boiler, heating area which is how much? 1.4MV electrically heated hot water boiler, its heating area is calculated, it needs to know the required heating power per square meter, heating, boiler pipes and boiler efficiency loss of these parameters, in order to obtain specific numerical values. If the heat required for heating power per square meter is 80W / h, boiler conduit 20% loss, then, the electrically heated hot water boiler heating area of 10,000 m2. However, this is the theoretical value, there may be some discrepancies with the actual value, without taking into account other external factors in this case.
Classification of Oil-fired BoilerCompared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas-fired boilers, such as gas-fired boilers, are the most expensive to operate, gas-fired boilers need to be opened with gas pipelines, then, if there is no natural gas pipeline, and hope that the operation cost of the boiler is low, only the choice of fuel-fired boilers. Fuel-fired boilers are heated by burners, and fuel-fired atomization effects Good fuel combustion, smokestack can not see black smoke, so fuel-fired boiler green, efficient and energy-saving. Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil.
Yesterday we learned that the Guangdong Province to increase pollution control efforts by the provincial people's government approval, Guangdong Province Market Supervisory Authority, the ecological environment of Guangdong Province, Guangdong Province, recently issued jointly approved by local standards "boiler air pollutant emission standards." Compared to the original standard, including contaminant particulate matter, sulfur dioxide, nitrogen oxides, etc. received strict emission limits help to further reduce the total emissions of air pollutants.
Provincial Department of environment-related offices responsible person, the current Guangdong Province "Boiler Air Pollutants Emission Standards" promulgated and implemented more than eight years, with advances in pollution control technology, emission control requirements of its apparent leniency. Meanwhile, Guangdong air pollution control task is arduous, urgent need to close strict standards, further reducing the total emissions of air pollutants.
Guangdong "boiler air emission standards" in the context of the implementation province domain for coal, the material forming the fuel oil, gas and raw fuel 65 tons of steam per hour and less steam boilers, hot water boilers of various capacities and Heat Transfer Material Heater; stoker various capacities, stoker furnace.
The new "boiler air pollutant emission standards" (DB44 / 765-2019) to adjust six major areas.
A clear the raw fuel material forming air pollutants emission limits fuel boiler;
Second, the received strict emission limits boiler air pollutants, increasing the emission limits coal boiler mercury and its compounds;
Third, the abolition of provisions different emission limits by functional area and boiler capacity;
Fourth, in particular an increase of atmospheric pollutant emission limit requirements;
Fifth, increase the fugitive emission control requirements;
Sixth, the excess air ratio conversion flue gas pollutants to the atmosphere of pollutants emission concentration of the reference oxygen content conversion, the oxygen content of the clear reference atmospheric pollutants fired boiler burning biomass.
The new standard in the province gamut execution, the execution time of the specific step-wise: new boiler effect since April 1 this year; the transformation of boilers give some time, depending on which region, from 1 July 2019 2020 or the date of July 1 implementation of the new standards.
