China industry gas steam boiler

China Association of boiler and boiler water treatment boiler technology plays in the development of healthy and clean technology development and lead the industry in an important position, and boiler manufacturers are inseparable, in the future, the Group will soon square to maintain good communication with the Association to promote the technological innovation industry, enhance the technological level of the industry, promote the vigorous development of the boiler industry to contribute their efforts.

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.

How to calculate gas consumption Gas china industry steam boiler 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.

How to use cheap coal-fired boiler, gas boiler and hot water boiler: gas china industry steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, slowing exhaust speed, increase heat transfer, high thermal efficiency, reduce user costs of coal-fired boilers, gas boilers, to achieve environmental protection, energy saving effect. Dust content of exhaust gas can be reduced by 30% to 40%. Mounting position: the oil pump is mounted between the nozzle and the combustion chamber or the ambient temperature should not exceed 360 ℃. Combustion apparatus exhaust gas discharged air pollution is greatly reduced. An exhaust gas of carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC) and other harmful components greatly reduced, harmful exhaust gases reduced by 50%.
