dhl series gas fired water tube steam boiler

Energy-saving boiler which brand is good, this is the majority of customers are more and more concerned about the problem. With the domestic attention to air pollution control, the surrounding areas of Beijing, Tianjin and Hebei in China have issued control measures according to the actual situation, among which the elimination of small coal-fired boilers is one of the important measures. Gas-fired boilers, oil-fired boilers and electric heating boilers all belong to energy-saving boilers, but compared with coal-fired boilers with serious pollution, the fuel cost is still higher, which increases the use costs of customers. Customers are also more concerned about the energy-saving effect of boilers, as far as possible to reduce costs. So which brand of energy-saving boiler is good? Now push for you. Recommend national A class boiler high-tech enterprise-Fangkuai boiler. Energy-saving boiler is a series of products that we focus on research and development of Fangkuai boilers. The thermal efficiency of natural gas boiler is very high, our Fangkuai can reach 95% or more, the emission of gas is very friendly to the environment, the nitrogen oxide is less than 30mg, which meets the relevant rules and regulations in our country. In some of the more remote areas, some countries have limited power to factories. At this time, the oil-fired boiler is a good place, with the domestic improvement of fuel quality, Fangkuai The continuous development of new technology has greatly improved the energy-saving effect of the boiler. Electric boilers can be said to be a leader in environmental protection boilers, but electricity is a valuable secondary energy source, and most of them are converted from coal-fired thermal power generation. Some areas are still short of electricity supply, and there is also a power limit every summer peak. Therefore, it is not the domestic promotion of energy-saving boilers. Another reason is that it costs about twice as much as a gas-fired boiler. Again, we strongly recommend a new type of energy-saving boiler-tubular boiler, which has a combustion efficiency of up to 96% and is very friendly to the environment, that is to say, the special performance of 3-minute steam output is available as soon as it is opened. Can save you a lot of fuel. Some customers may think that compared with traditional boilers, the price is a little more expensive, but what we have to say is that we have reasons for expensive, high-tech applications have greatly improved thermal efficiency, saved a lot of fuel, from the long-term investment use, The price-to-performance ratio is super high. Through the above understanding of energy-saving boilers, I believe you have a certain understanding of our Fangkuai boiler brand, want to have a more in-depth understanding, please call our hotline, more sincerely invite you to visit the plant, study.

4 tons of dhl series fired water tube steam boiler before firing what needs to be done to prepare a deal boiler conduct a comprehensive inspection before Sheung Shui, the water is softened before boiler water filling. 2, Sheung Shui should check whether there is water leakage valve, leaks should be immediately removed when found. 3, the check Sheung water temperature, pressure gauges, water level, no good production of inlet and outlet valves, smoke profile, said shutter is flexible, the flue gas channel is smooth duct, each cleaning doors are tight. 4, before firing coal with water 8-10%.

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.

March 25, 2019, which is bound to be a special day. 0900, sunny, cloudless, in my company's plant research and development center Plains Plaza, held fast Boiler "academician workstation," the opening ceremony.
