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.

The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.

The purchase of gas-fired boiler, we are more anxious shopping center, but for gas-fired boilers are not very understanding. After the introduction of others, we understand each other fast boiler more comprehensive, and more trust fast boiler. After the boiler put into use, it turns out, party fast products fully meet the needs of our shopping centers. --customer feedback

9 major technical characteristics of the gas 20 ton fired hot water boiler use for center heating you know? 1, according to atmospheric boiler design, boiler in a non-pressure state, there is no safety hazard. 2, the use of advanced multi-layer insulation centrifugal glass wool, steel for packaging famous white color, heat loss, anti-rust appearance 3, burner configuration imported brands, high degree of automation, automatic purge controller according to the instruction, the electronic auto-ignition, automatic combustion (gas) automatically adjusting the ratio of wind oil, security and stability performance, good combustion. And there are flameout protection device, ensure safe operation. 4, the computer controller hot water boiler, all the functions are stored on a magic smart chip, a key to power boilers, automatic timing, temperature operation, the user can set the start, shutdown time, after setting, without special duty, save time, and effort. 5, the inner fire tube inserted spoiler retardant, smoke slow speed, to strengthen the heat exchanger, the temperature of the flue gas discharged from a low smoke chamber, reducing heat loss and save fuel. 6, large font display temperature, easy to grasp and boiler operating conditions of the system, the water temperature can be freely set from 10 ℃ to 90 ℃, automatic boiler or heating system to provide users with life, bath with hot water. 7, the control system in accordance with the temperature control of boiler water circulation pump start and stop, boiler water circulating pump starts when the water reaches an upper limit temperature, lower than the hot water circulation pump stops when the water temperature lower limit. 8, horizontal fuel gas hot water boiler three return all wet back structure, using a large furnace, rough smoke tube design, increased furnace radiation heat absorption, the effective energy saving. Using threaded pipe and waveform furnace, greatly enhanced heat transfer effect, greatly saving fuel consumption. 9, while the machine is equipped with thermal protection (ultrahigh temperature furnace, the burner is automatically stopped and an alarm buzzer, the second over protection (the boiler shell temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), the lack of anti-dry protection of water (when water is lower than the low water level of the furnace, the boiler is stopped and an alarm beep), a boiler leakage protection (the control system detects electrical leakage, short circuit, automatically cut off the power).
