Unorganized 1, thermal power, cement, brick building materials, steel coking, coal-fired boiler, shipping, ports and other particulate matter emissions from the more serious business section and complete the depth remediation. Advanced nitrogen crew embodiment encourage gas, coal-fired units embodiment plume off white vapor recovery control. Before the end of June 2020, to achieve a comprehensive discharge standards garbage incineration industry.
2, to enhance the proportion of natural gas. Orderly development of natural gas peaking power plants and other interruptible user, in principle, to new natural gas cogeneration and gas chemical projects.
3, the implementation of total coal consumption control. By 2020, the total control in less than 27 million tons of coal; coal power accounted for the city's total coal consumption to increase the proportion of more than 65%. Continue to promote alternative energy coal and oil by 2020, electricity consumption (calculated as the supply of coal equivalent) accounting for over 60% of the total social energy consumption.
4, elimination of old coal-fired units. For shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. No new coal-fired units, the new rely mainly on the area of non-fossil energy generation and transport electricity to meet foreign consumption.
Steam boiler heating in winter north of the advantages and disadvantages of our country, cold weather, heating is essential, often used before coal-fired boilers for heating, but coal-fired boilers to serious air pollution, now gradually replaced by 1000kg per hour steam boilers. Steam boiler is also very common type of heating equipment, are now gradually penetrate to the south. Steam boiler heating both advantages and disadvantages, we compare: first, an analysis of the advantages of using pulverized coal combustion boiler, the coal is in fact relatively high temperature, the surface temperature of the steam boiler is relatively rapidly increased, but in fact, this system can withstand particularly low cooling system. 2, the steam in the evaporation process, as in fact it is the gas density is quite small, for which the net pressure steam boiler itself is relatively small. 3, the steam itself does not require any external pressure resistance of the propulsion system for it. 4, steam boiler has a clear advantage, the heating effect and very fast, but it stopped gas speed is faster, especially for users of intermittent heating. Second, an analysis disadvantage, during use in a steam boiler, because the pipe is relatively high stability, and is not easy to heat, in the course of prolonged use, the dust around the surface of the device, so that the relatively poor surroundings, and heat slowly dispersed, easy to burn people. 2, in a more simple production conditions, the use of the boiler does not care, and the system will cause leakage particularly large heat loss, so that the waste of energy is relatively more serious. The disadvantage of steam boilers we could have been avoided, in use of the process will be seriously careful to avoid being burned or wasted energy.
Gas boiler precautions required during installation methods, or steps :( a) a foundation base of the boiler should be provided is determined according to the local soil, manufacturers design reference by the civil sector again. After reaching the base strength boiler, the boiler should drawings inspection and acceptance, and to draw the whole boiler three reference lines: a, longitudinal reference line - drum center or the center of the combustion apparatus. b, lateral reference line - the center of the front axle or chain grate slag centerline of the machine. C, elevation reference line - can be selected from a number of locations about four weeks, respectively, on the basis of the marking, the relative offset between the markers should not exceed 1mm. Furnace in place. After assembly the lower part of the boiler in place first, then the upper assembly large, the upper and lower portions need to find a combination of two positive pads firmly, should be both inside and outside the two casting. Installation location and size deviation test methods according to GB50273 "boiler installation engineering construction and acceptance" implementation. (B) lifting the boiler, during lifting, should be suspended on a lifting lug drum boiler ready large, the boiler on a foundation base coincides with the pre-drawn reference line. The longitudinal centerline of the boiler and the foundation, the deviation is not more than 3 mm, and the inclination with the center line of the drum hammer correction, allowing the central drum inclination is not larger than 5 mm, otherwise use horns foundation base and the junction pad level. Maximum level (c) Installation of boiler network (1), water supply conduit installation requirements typically require as backup pool below the normal water level line of the boiler, so as not to shutdown, boiler feedwater flowing into a large number of drainage caused to start the next . At the outlet of the tank (i.e., an inlet feed line) should be installed wire screen. (2), a main steam line installation requires the main steam lead pipe straight run section should be more than 0.5 m, the bending radius should be 4-5 times the diameter of the pipe, the trap should be fitted at the lowest line in order to prevent water hammer pipe, while to be reliable insulation. (3), the safety valve should be installed in the valve installation requirements after the hydrostatic test, the safety valve shall be fitted exhaust pipe, the exhaust pipe of the safety guide outside the boiler house, allowed valving the exhaust pipe. (4), mounting a lower water table level table downcomer must access a safe place, Hancock rotating flexible water table, not leaking, water table must be installed to the lighting device, easy to observe. (5), a pressure gauge mounting means so that when the scale gauge vertical plates, should be painted red gauge scale to show the maximum allowable pressure boiler, rotating flexible plug gauge, not leaking, water flow, pressure gauges insulation prohibited. (Iv) the boiler chimney installation requirements, when lifting the chimney, the chimney should be straight, horizontal direction lead length should not be too long, generally less than 5 meters, the height of the chimney should comply with relevant national standards. To add chimney rain cap, the weight of the chimney should not fall directly on the boiler chimney take over the host. Installation (e) combustion system: 1, according to the combustion system of FIG power line control circuit, a control signal line and the control line is electrically connected, the program should be installed reliable ignition and flame failure protection devices. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine.
Henan gas boilers What are the advantages and disadvantages? Henan gas boiler is a clean burning natural gas for industrial boiler energy section of industrial production output of hot water and steam. After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, the gas boiler should be transported from Henan, breaking coal boiler "thriving" situation. Compared with conventional oil-fired boilers, coal-fired boiler, gas boiler Henan has unparalleled advantages, mainly in the following areas: 1, Henan artificial gas boilers and low consumption of water and electricity costs; 2, gas-fired boiler flue gas of Henan or promote condensation energy technology, it greatly enhance the thermal efficiency further, when the exhaust gas temperature Henan gas boiler is reduced to 80 degrees or less, up to 95% efficiency; 3, Henan environmental clean gas boiler, a small area of the boiler, low failure rate, significantly improve the use of units on-site environment, adequate supply and lower prices, environmental requirements higher cost areas of comparative advantage of obvious; 4, due to the Henan gas-fired boiler using clean energy, so when burned does not produce soot and dust in the furnace, so the operating life than other types of boiler long. However, due to the environmental advantages of natural gas and energy in a growing proportion of supply and demand and Jiazhiguilv bound to make the country in the future and gradually it with other primary energy prices linked to float, its long-term price trend will gradually open. In addition natural gas shortages in some areas or seasonal shortages also affect the reasons for its further promotion. On the whole, the use of gas-fired boiler more good than harm Henan, Henan to promote the use of gas-fired boiler is still the trend. Van de force as a professional boiler boiler supplier, in terms of Henan gas boiler series of development and exploration, successfully developed a low nitrogen gas boiler Henan, have made outstanding contributions to technological innovation in Henan gas boiler.Free Chat
