In order to ensure the completion of the 2017 goals and tasks identified in the Air Pollution Prevention Action Plan, and to improve the ambient air quality in Beijing, Tianjin and Hebei and surrounding areas, in 2017, in Beijing, Tianjin, Shijiazhuang, Tangshan, Langfang, Baoding, Hebei, Quzhou, Hengshui, Xingtai, Handan, Taiyuan, Yangquan, Changzhi, Jincheng, Shanxi Province, Jinan, Zibo, Jining, Dezhou, Liaocheng, Binzhou, Heze, Henan Province, Zhengzhou, Kaifeng, Anyang, Hebi, Xinxiang, Jiaozuo, Fuyang 28 Cities (referred to as “2+26” cities) implemented the key winter cleaning and heating projects.
The “2+26” city will be listed as the first implementation scope of the winter clean heating plan in the northern region. Comprehensively strengthen the management of scattered coal in urban villages, urban-rural junctions and rural areas. Beijing, Tianjin, Langfang and Baoding will complete the construction of “forbidden coal zone” before the end of October, and further expand the scope of implementation to achieve clean heating in winter.
Before the end of October, other cities in the transmission channel will complete 50,000-100,000 households to replace coal or electricity to replace coal in accordance with the principle of being qi, gas, and electricity. Increase the use of low-grade waste heat and geothermal energy in the industry.
Zhongrui brand constant piezoelectric hot water boiler is composed of boiler body and supporting control cabinet. The design, manufacture, inspection and acceptance of this product shall be subject to the provisions of the "Safety Supervision Regulations for Small and Normal Pressure Hot Water Boilers" and "General Technical Conditions for Atmospheric Pressure Hot Water Boilers" and "Technical Conditions for Electric Heating Boilers".
1. The working pressure of the atmospheric pressure electric hot water boiler is normal pressure, and the gauge pressure is 0 MPa. Designed for return water temperature of 85/65 ° C, thermal efficiency of not less than 98%.
2. The furnace body is made of boiler special Q235 steel plate to achieve safe use of the furnace body.
3. The electric heating tube shell adopts the standard SUS304 seamless steel tube with high temperature resistance, corrosion resistance and good stability, which is suitable for various water quality. The heating tube should have uniform heat transfer and good insulation.
4. The heating pipes are arranged reasonably, and the wiring structure of the heating pipe group is detachable.
5. Each group of heating pipes can be started and shut down separately, so that the heating pipe group can be segmented and cycled to avoid large impact on the power grid when the equipment is started and operated.
6. The safety protection function in the control cabinet has the basic operation protection functions such as over temperature, over pressure, overload, short circuit, leakage, water shortage and so on. In the event of an abnormal situation, the unit should give an audible and visual alarm and automatically cut off the heating device until all the cuts are stopped.
7, the operating system is fully automatic microcomputer control.
8, electrical components use domestic Chint brand, also optional Schneider, ABB and other electrical components.
9. The electric hot water boiler adopts the integrated mode of the furnace body and the control cabinet, and the electromechanical integration facilitates the installation of wiring and maintenance.
10. The product is packaged and transported in accordance with the boiler standard.
11, power supply 380V, 50Hz.
Zhongrui brand electric steam boiler:
1. The water volume of the furnace body is small, and the steam production is fast, meeting the needs of users;
2. Located in the large-capacity steam chamber on the upper part of the main body and the steam-water separation measures in the pot to ensure high-quality steam at any time;
3. The furnace body has built-in extremely low water level protection device to detect the change of water level in the furnace body at any time to avoid dry burning of the furnace body and cause safety accidents;
4, equipped with high-quality safety valve, globe valve, liquid level electrode (Japan Omron) pressure gauge and pressure controller and other safety accessories to ensure reliable operation;
5, equipped with high-quality water level gauge, the boiler water level is clear and arguable;
6, vertical structure, compact and beautiful, small footprint, elegant shape, bright color;
7 Optional high-performance control system, strong anti-interference ability, convenient maintenance, safe and reliable work, ensuring long-term stable operation of the boiler in harsh environment;
1. Over-temperature interlock protection: When the temperature inside the boiler exceeds the set value, the heater is prohibited from working and an alarm is given.
2. Water shortage protection: When the boiler is short of water, the heating tube control circuit is cut off in time to prevent the furnace body from being burnt and damaged, and the controller issues a water shortage alarm indication.
