Note the choice of industrial boilers from the first industrial revolution to develop microbial technology, and upgrading various products continue to emerge, led us to the development of human civilization from the original backward to technological civilization, to the boiler, for example, since the last century, there has been a cylinder since the boiler-shaped, with the needs of science and technology and production, from simple to complex, from single to serialization, boiler technology are developing rapidly, the good reputation of industrial boilers companies choose to share precautions industrial boilers; first, the coal use; the design of the cell structure based on coal boiler components as the design basis, select the boiler should pay attention to adjust to the type of coal in the region. It recommended new, high-efficiency, high-tech, high-quality, durable industrial boilers; second, parameter selection; industrial efficiency boiler work normally when approaching the highest efficiency rating, as the load decreases efficiency has declined. Boiler capacity is generally selected: it generates a large steam than the actual gas consumption, such as the required parameters and actual parameters difficult to match industrial boilers, high boilers in this case a gear selection parameter. Selection of auxiliary boiler should also refer to the above principles, to avoid the "big horse car"; third, the number of choices; normal maintenance of industrial boilers and boiler shutdown is a number of factors, but also pay attention to: the boiler room shall not exceed the number of boiler economizers work load, install boiler economizer device purpose is to avoid too much heat when the smoke away. Improve the thermal efficiency of the boiler, is provided in the back pass boiler economizer heating surfaces, the use of flue gas heating boiler feed water, to save energy, economizer after the installation, the boiler increases the thermal energy required for heating the feedwater, boiler water and so reducing the temperature difference between the water supply, reduce the burden of heating boiler feed water. Cause excessive number of boiler economizer can not play a role, resulting in waste of energy; These are high-quality industrial boiler company to share some notes selected industrial boilers; vast land of our country, many places are rich in coal, resulting in different types of coal , which has also become a basis for selection of parameters and select the number of boilers enable us to be more effective in energy conservation, to achieve a win-win.
To further reduce emissions, improve air quality, the Shanghai Municipal Government put forward the views of accelerating the implementation of small and medium sized boilers mentioned standard transformation of the urban area. Details are as follows.
As of 2020 before the end of September, the city mentioned standard transformation is completed with small boilers. Among them, the city center before the end of 2019 to complete the transformation mentioned standard, to Shanghai, "Boiler Air Pollutants Emission Standards" (DB31 / 3872018) requirements, to encourage compliance in advance.
In January 2018 - September 2020 period, complete boiler mentioned standard transformation and acceptance, discharge standards under the "50%, 75%" and other major conditions of the city's small and medium-load boiler unit.
City, District, together, support the implementation of fiscal policy. Giving special one-off subsidies, municipal and district levels in line with the financial support of the above-mentioned range. Specific binding transformation of the former boiler capacity and completion time, be supported in accordance with the following criteria:
Boiler "four" leakage phenomenon determines: whether the output of hot water, steam or thermal oil, and regardless of using coal, oil, gas, biomass or power boiler, has the following "four", respectively, of boiler waterwall tubes, superheater tubes, reheater tubes and economizer tubes. It covers all four pipes of the boiler heating surface, the internal pressure of the working fluid bear, may be external to bear the high temperature, harsh environment corrosion and wear, excessive reconcile between water and fire, where the energy is concentrated is passed .
What works and characteristics of natural gas boilers are? Gas-fired, the main structure of a shell boiler, furnace, turning smoke chamber, and other components of the smoke tube boiler is suitable for light oil, heavy oil, natural gas, gas and other fuels, the boiler reasonable structure, double-layer anti-burn, facilitate flue gas is fully utilized, and also has a small footprint, easy installation, high steam quality and so on. Works natural gas boilers are: water through the inlet into the boiler, heating boiler after heating meet the water quality standards, into the interior through the radiator circulating pump to heating by radiation and convection heat transfer, water flowing through the radiator, back inside the boiler is heated, and then again into the radiator, so the cycle is carried out. And the system of gas-fired, can also provide hot water to meet their basic needs, the boiler water temperature and the indoor temperature, a temperature sensor after the treatment, the temperature signal is transmitted to the microcontroller, through the corresponding drive circuits to adjust corresponding pipe size valve, and further by controlling the temperature of water, heating to achieve the purpose, the user according to the size of the heating range, select the appropriate circulating pumps, to do so is also more economical and convenient.Free Chat
