Gas fired water tube boiler water treatment in the application of protective measures II: to prevent the boiler fire blasting has been included in the ministerial twenty counter-measures, including fire protection, including the FSSS has been promoting the use of many power plants, it highlighted a few points : 1. references to the fire blasting. Key anti-ministerial twenty measures of the five. Called boiler fire to prevent shooting accidents. The blast furnace is correct formulation, because electric boilers, oil-fired boiler and gas furnace boiler furnace explosion caused damage not only in the operation of the fire, the flare ignited focused overhaul of combustibles and purge the ignition is not the same explode resulting in damage to the furnace.
The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam fired water tube boiler to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
Gas fired water tube 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.
Henan gas fired water tube boiler manufacturers introduce safety precautions 1 boiler, gas boiler burners in Henan launch process, if the gas boiler burners Henan repeat alarm determine reasons should be identified, identify and solve problems and then press the reset button, continue to launch. Note: Continue to press the reset button must not exceed 10 seconds in time. 2, Henan gas boiler burner once burned without success, should restart the boiler fan, ventilation until five minutes before the 2nd burner burning operation launched. 3, during the normal operation of Henan gas boiler, burner close to the thermal equipment parts (such as flange adapters, etc.) will be very hot, to prevent burned. Do not place near flammable materials to avoid fire. 4, a gas boiler operation Henan close supervision is necessary in hot water circulation pump and boiler pressure, natural gas sub-packet, pipe valves, pressure gauges, flow meters, 5, open the door or investigations of the door from the furnace when the flame, fireman should wear gloves, and sideways investigation. 6, Henan gas burner boiler to keep clean working environment dry, especially flame detector (i.e. electric eye) should be kept clean, can not damp the control circuit portion, the high temperature; class burner to be cleaned and maintenance time. 7, the filter during use, should be based on the case with contaminated fuels, often view the cleaning or replacement of the filter cartridge. 8, Henan gas boiler electrical equipment to view, mainly: whether the damaged wire, jacket damage, without loosening the screws, the contact is good, the motor is running any abnormal sound and so on.Free Chat
