hot water boiler for restaurant india price
Since 2019, Taiyuan continue to adhere to the principle of priority to improve air quality, in order to significantly reduce heavy pollution weather as the main direction, ongoing action to combat air pollution, management depth to promote coal-fired boiler to achieve 35 tons of steam coal-fired boilers "clear zero".
In accordance with the gas will change, given the need for, after the first stand broken, do not break the principle of non-stand, Taiyuan will continue to carry out the transformation of rural areas, clean heating, heating is expected to complete the transformation of 30,000 before the end of October, the city's rural areas clean heating coverage rate reached 70%.
To reduce coal pollution, coal-fired boiler will also promote the in-depth treatment. October 1, seven more than 65 tons of steam coal-fired boilers and ultra-low emissions completed the transformation. Seven out of 35 tons of steam coal-fired boilers to achieve 35 tons of steam coal-fired boilers all clear.
In the region of the pollution control aspect, the binding improved air quality requirements, the complete electricity instead of coal, coal gas for generation of clean alternative energy area, included in "ban on coal zone", the implementation of joint sheet control. Meanwhile, to further increase the intensity of investigation ban within the "ban on coal zone" small coal-fired facilities, enhance the level of protection clean heating, ensure clean heating effect, and resolutely put an end to bulk coal burning complex, consolidate the "ban on coal zone" construction achievements.
In terms of market control, prohibit the use of more than 1% sulfur, ash than 16% of the civilian bulk coal. Before the end of the civil bulk coal sampling of coal sales business monthly coverage rate of 10%, annual sampling coverage of 100%. Investigated sales of low quality coal units and individuals in accordance with law, concentrate on cleaning up, straighten, banning non-compliance bulk coal supply channels, to crack down on the use of low-quality coal sales behavior, non-coal washery slime, the coal into the civilian market.
Special attention are:
1, drum boiler working pressure greater than the rated pressure. (If a pressure boiler plate 6MPa, drum operating pressure of 6.8 MPa);
2, if the operating pressure is 1.25MPa, then the calculated pressure is 1.29MPa (GB / T9222-2208) of the relief valve set pressure (low) 1.04X1.25 = 1.3MPa, (high) 1.06X1.25 = 1.325MPa ;
(4) Horizontal combustion WN (the horizontal) (5) Horizontal combustion WW of (lying outside) (6) horizontal heat pipe WR (horizontal hot) water tube boiler vertical single drum DL (stand-alone) single-drum longitudinal mounted the DZ (single-longitudinal) single drum transverse formula DH (single transverse) double drum vertical type SZ (double vertical) horizontal type double drum SH (double cross) rows of stationary furnace G (solid) activity grate hand H ( live) feed grate A (down) the chain grate L (chain) reciprocating grate W (to) pumping plate lifting furnace C (pumping) chamber burners S (chamber) gas furnaces half B (semi) boiling furnace F ( boiling) 4, boiler pressure applications because unpressurized pressure hot water boiler for restaurant india price, so to link with the atmosphere, and the temperature should not exceed 100 ℃. The main areas of use: place heating, bathroom, nursery, electroplating, chemical without high temperature (higher than 100 deg.] C) of. However, once the system layout is unreasonable, without the openings communicating with the atmosphere communicating pipe or valve blockage or installed, it will cause pressure hot water boiler, having a certain degree of risk. 5, pressure boiler water quality: Water pressure boiler required to follow "industrial boiler water quality standards," the specific requirements in the following table: 7, the boiler operating temperature and pressure: The "small hot water boiler and pressure monitoring Safety Regulations" regulations, the atmospheric outlet of the water heater temperature should not exceed 85 ℃, the return water temperature of 60 ℃. Low pressure type water temperature can not exceed to 95 ℃, return water temperature is 70 ℃? Because in security considerations, to prevent heating of the hot water temperature is too high so as gasification, the system will affect the circulating pump running, the system pressure rise; and if failure or insensitive because the thermometer is not allowed to set the temperature are likely to cause system overpressure thus a security risk. Pressure hot water boiler thermometer scale used rated water temperature of 1.5 to 2 times the rated water temperature and the temperature difference between nominal water temperature not more than 20 ℃.
Temperature ranges and boiler water boiler furnace can drink: Vertical shell boiler in the boiler, which has its specific species? Central boiler furnace temperature, how much it is? In addition, water boiler, it can be directly drinking it? Why raise these problems, its main purpose is to be completely resolved, so that we have to learn content, and further deepen familiarity and level of understanding of the boiler. 1. Vertical shell boiler, which has its specific species? Vertical shell boiler in the boiler, which in the specific species, there is a vertical cross main water tube boilers, water tube boilers of vertical straight, vertical bent water tube boilers, as well as four vertical fire tube boiler. And now, in these species, the latter three, is the straight vertical water-tube boilers, water tube boilers of vertical bending and vertical fire tube boilers, are using more.
