gas vertical hot water boiler

gas vertical hot water boiler

Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon vertical hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.

What are the technical parameters of the gas boiler boiler parameters are: 1, boiler capacity, which is the output Q, units of steam boilers are tons / hour representation. Hot water boiler for heat MW / h represents; 2, pressure P, the unit is Mpa; 3, steam (or superheated steam) Temperature q, in degrees Centigrade. Hot water boiler expressed in terms of outlet temperature and return water temperature. Another area of ​​the heating surface of each grate area, fuel type, fuel consumption, water temperature, total drag, with the wind (the wind drums) the amount of exhaust gas temperature and the like. The expression model are: the number of drum (e.g., single drum D, S, double drum); drum arrangement (transverse type H, the Z vertical type); combustion (chain L, G stationary grate etc.); a fuel type (coal a, gas Q, Y fuel, etc.); a steam boiler is usually "tons / h" or "t / h" is the capacity of the boiler. With "Mpa" or "MPa" (old unit of "kgf / cm 2" or "kgf / cm2") of the rated pressure of the boiler, it represents the temperature at the rated pressure saturated steam and superheated by "deg.] C" (Celsius) steam temperature. Thermal Efficiency Heat Transfer Fluid is a boiler furnace or a thermal transfer process, heat is absorbed by water, steam or thermal oil, accounting for complete combustion of the fuel into the boiler heat released percentage capacity of 1t / h steam boiler, i.e. It indicates that the boiler may be over 1 hour into water of 1 ton capacity of saturated steam under pressure; 0.7MW of such water heaters and furnaces heat Transfer Fluid representations may generate heat corresponding to 0.7MW power over 1 hour ( equivalent to one ton of steam heat). Two water boiler is the heating means for the vertical hot water boiler working fluid. Usually "MW" (MW), with the old unit "when Wan kW /" or "million kcal / h", namely "104kcal / h" is the capacity of the boiler, with "Mpa" represents the rated pressure of the boiler, with "℃" the hot water temperature.

4 tons steam boiler fast boiler's Henan small series with you briefly quick 4 tons a steam boiler. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of a steam boiler. He said first boiler say "pot." This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessel, the safety device is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used.

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.
