SUMMARY boiler electric heating, electric heating boilers, also known as electric boilers, heating boiler, as the name implies, it is the power for energy and converts it into heat energy, so that after conversion boiler, steam having a certain outside thermal energy output, high temperature water or organic heat boiler equipment. Electric boiler steel shell mainly by the electrical boiler, computer control systems, low-voltage electrical systems, electric heating tubes, instrumentation, and access to water and other components. Electric boiler heating induction heating and the resistance (electric heating) was heated two ways. Resistance heating system is divided into stainless steel heating tubes electric boiler, electric resistance heating boilers and ceramic heating tube which uses a resistive heating element for heating the tubular, electric boiler is structurally easy combination of superimposed flexible control, easy maintenance and replacement. Electric boiler heating characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage.

Recently, Dezhou City, Shandong Province, has released the main points of pollution prevention and control in 2019, set specific targets and implement measures to control emissions of persistent pollutants SO2, NO2, to reduce the number of aspects such as severe pollution days.

1, continued to promote the total coal consumption control. Strictly implement the coal consumption reduction, equivalent alternative policy requirements. Continue to implement the monitoring and early warning mechanism to control the total amount of coal, coal consumption for the counties (cities, districts) were scheduled monthly, quarterly analysis, forecasting and early warning and timely release. Refined coal decomposition control mission objectives to ensure the completion of the annual total coal consumption control tasks.

2, strengthen renewable energy development and utilization. Actively promote wind, solar, biomass, geothermal and other renewable energy sources, promotion of power generation, industrial and residential heating and other heating applications. Achieve renewable energy consumption accounted for the proportion of primary energy consumption of more than 15%.

3, continue to promote the management of coal-fired boilers. The existing 35 tons of steam coal-fired boilers, according to ranking policy before the end of 2019 included in the phase-out plan. The inclusion of out of range, to ensure that out of the task before the end of 2020.

4, the implementation of low NOx combustion gas boiler reconstruction. To 2020 basically completed the transformation of low-NOx combustion as the goal, listing the existing inventory ledger gas boiler, to determine the transformation of an object, complete renovation in 2019 total about 50%. After transformation of NOx emission in principle higher than 50mg / m3. Achieve a stable concentration of nitrogen oxide emissions rebuilt 30mg / m3 or less (that is, ultra-low NOx combustion requirements) can be appropriate priority in provincial subsidies make up ecological civilization prize funds.

5, continue to promote clean coal. Strengthen clean coal production, supply, construction and distribution system, and continue to improve the implementation of the subsidy policy, to ensure the timely distribution in place to protect the people warm winter. Bulk coal market to strengthen the comprehensive improvement of law enforcement, the implementation of three coal detection mechanism to prevent inflow of low-quality bulk coal, clean coal to ensure quality standards. 2019, on the basis of full coverage in clean coal, continue to promote clean coal.

6, strengthen high-pollution fuel combustion zone ban construction. Combustion zone ban, a ban on new or expanded high-polluting fuel burning facilities have been built to the deadline to switch to clean energy. Investigate and punish illegal construction, expansion and high-polluting fuel facilities are not completed within the prescribed period rectification behavior. Ban on burning coal for a total ban on the circulation area.

7, continue to promote clean heating transformation. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. Accelerate the pace of production, supply and storage of natural gas marketing system construction and gas storage facilities, improve air support capabilities. To develop multi-gas source, priority for clean heating, ensure safe and stable gas. Strengthen heating, gas facilities construction, expanding the central heating, gas, geothermal heating coverage. Accelerate the clean heating renovation project, before November 15, 2019 to complete the annual task of transformation goals. Complete power-generation coal, gas and other clean coal generation of heating transformation of the region, a total ban on bulk coal sales, to prohibit the sale and hoarding bulk coal, bulk coal to prevent the re-burning.

2, rapid cooling furnace water treatment. After the shutdown can not continue to feed water to the boiler.

When there is no water leakage or water, the cooling time can be shortened, accelerated cooling rate, cooling down the sewage water through alternate methods, and maintain the level.

In the boiler production, daily use and installation process must be through welding treatment, then in the boiler welding problem what needs to be paid attention to? Next, we will ask the technicians of Fangkuai Boiler Factory to give us a special introduction: the boiler's furnace tube and boiler's oven box and pipe should be connected by means of welding. Only the boiler tube and the furnace box pipe welding can make it more firm. It is important to note that the heating part of the boiler should be linked by butt welding and bottomed by arc, so as to conform to the overall structure of the boiler. When welding parts of the boiler's edges and corners, it should be maintained. The roundness of the welding joint can not appear some small defects, otherwise, these are very easy to cause the operation failure and safety hidden trouble in the process of use.
