Coal-fired boiler not only seriously polluted air, which produces a large amount of waste water sludge can also cause serious water pollution and soil contamination. To protect the city of Tongren green water blue sky, since 2014, led by the city of Tongren City, Guizhou Bureau of Quality Supervision, of 10 steam tons / hour within built-up areas and Tongren City High-tech Zone, Economic Development Zone, Tai Lung range and below, in Guizhou tobacco industry limited liability company Tongren cigarette factory, Tongren City, drug rehabilitation centers, Tongren Wantong construction and development Co., Ltd. and other 36 enterprises of coal-fired boilers to carry out an intensive diagnostic investigation. One by one on the ground to verify the registration, and the companies signed an undertaking to ban coal-fired boilers eliminated; to effectively reduce the burden on enterprises, according to the spirit of the document, to take the initiative within the time limit or eliminate the use of coal-fired boiler unit to switch to clean energy, the after review and acceptance Municipal Environmental Protection Bureau, according to the amount of coal-fired boilers hour evaporation reward, award criteria tons of steam per 30,000 yuan subsidy.

Up to now, the city of Tongren out of 36 coal-fired boiler units, a total of 43.051 tons of steam, an award subsidies 1,291,530 yuan, so far, the city of Tongren jurisdictions total phase-out of all coal-fired boilers, and lay a good foundation for the creation of ecological civilization demonstration area.

How to calculate gas consumption Gas 8t steam boiler low price turkey Gas steam boiler air consumption how to calculate: there are a lot of users do not know how to calculate the gas consumption of gas steam boiler steam boiler gas before you buy, there are many user calls consultation, the issue it has been plagued by some users, this morning it decided to write articles about it again, "how gas consumption gas steam boiler computing", following on from me explain to you about the principles of operation of the gas boiler gas consumption formulas and gas boiler. 1. First, we first look at the gas steam boiler operating principle: the pressure of the fuel through the gas line is controlled by the flow valve through the ignition burner Automatic combustion air, the heat emitted by the heating surface of the boiler sufficiently absorbed (three return) flue gas (carbon dioxide and water) into the atmosphere through the chimney. 2. Gas-fired steam boiler fuel consumption cost analysis (we have a 4-ton gas-fired boiler, for example) fuel light oil and gas projects Rated evaporation 4t / h2t / h thermal efficiency of 92% to 92% fuel heating value 8500Kal boiler / Nm310300Kal / Kg fuel consumption amount 300Nm3 / h24Kg / h auxiliary mechanical and electrical consumption 11KW · H11KW · H fuel Price yuan / Nm3 yuan / Kg fuel costs per hour yuan per hour RMB auxiliary mechanical and electrical consumption costs the first year cost of fuel (million, according to 350 days / annualized) in the auxiliary equipment costs (million yuan, according to 350 days / year basis) of the total cost (million, according to 350 days / year basis) (Note: at 12 hours per day) 3 can be roughly summed up the table above to see a: full load per unit time difference of many operating costs, especially compared with the fuel gas. Of course, its operating advantages and disadvantages: the relative running disappointment source gas boiler in terms of impact, but the large-capacity electric boiler operating electrical equipment network difficult and requires a large-capacity transformer request by; fuel oil boiler by factors influence the larger. In terms of environmental protection, the most environmentally friendly power, followed by gas and oil. In terms of operating costs, natural gas is the most economical, followed by oil and electricity. Proposed conditional user preferred gas boiler, not only because of its low operating costs and environmental protection.

The difference of fuel between Oil-fired Boiler and Gas-fired BoilerOil-fired boiler refers to the fuel-fired boiler, including diesel oil, waste oil and other oil boilers. The overall arrangement of the oil-fired boiler is similar to that of the coal-fired boiler, except that the bottom of the furnace of the oil-fired boiler is mostly made into the bottom of the insulation furnace with a tilt to the back wall of 10 °~ 30 °, in order to obtain good combustion characteristics. In order to atomize fuel oil, there are two types of fuel burner nozzle: mechanical centrifugal injector and steam atomized Y type injector. The fuel of the oil-fired boiler is the fuel (such as diesel oil, kerosene, etc.). The fuel of the gas-fired boiler is gas (such as natural gas, city gas, biogas, etc.), depending on what fuel the boiler burns. The difference between a fuel-fired boiler and a gas-fired boiler is what kind of fuel burners are used to burn the gas-fired boilers, which are called gas-fired boilers, oil-fired boilers with fuel-fired burners, and oil-fired boilers called oil-fired boilers.

Principles of 8t steam boiler low price turkeys and solutions hydraulic external gear of Henan fast boiler's small series with you about the principles of steam boilers and solutions Steam Boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil three kinds of steam boilers, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, large steam boiler return of more than three horizontal structure . If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories. From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blowing into the combustion chamber is a lower place, such steam boilers greater resistance, require forced air. Steam boiler cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. Steam boiler flue gas from the back of the boiler, the steam drum of a boiler return line before the smoke tube, returned by two return rear smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. These are the works of steam boilers, steam boilers run course, ultimately, other devices, such as induced draft fan not only bear the task of exhaust fumes, or negative pressure necessary for operation of the steam boiler. As well as pressure vessels, thermometer, safety valves, pressure gauges, pumps, steam pumps, and so on. They are essential for steam boiler work. Pump leaks. Gear pumps for leaks during operation, leading to its actual output is smaller than the theoretical flow of traffic. The main channel is leaking gear pump: through the gap between both surfaces and both side surfaces of the gear cover side leakage, accounting for 75% to 85% of the total leakage of the pump; radial gear tip circle between the inner hole and the pump CLEARANCE ; gap by engagement of the gear leak. The gear pump due to the presence of a leak, so that the output pressure do not increase, the influence of the use of a gear pump. In order to solve the low gear pump output pressure problems, may be employed on both sides of the elastic gear plus floating collar or baffle manner, to reduce the leakage of the gear pump, the gear pump to increase the output pressure. Radial force imbalance. In the gear pump during operation, the pressure acting on the outer gears are not equal, resulting in the gear and bearing at the axle radial imbalance force. This unbalanced force will accelerate the radial bearing wear and reduce the service life of the bearings, the gear shaft deformation can also cause friction with the inner hole of the addendum pump, pump damage, so that the pump does not work. The solution generally adopted is: ④ opening pressure balancing grooves to the pump, the high pressure oil introduced into the low pressure zone, but will increase the pump leak, the influence of the volumetric efficiency of the pump; ② size reduction oil pressure chamber, acting on the teeth the pressure area is reduced, thereby reducing the radial force imbalance.
