fire tube automatic gas steam boilers

fire tube automatic gas steam boilers

The origin of the gas on the principle of using gas fire tube automatic steam boilers steam heating boiler called gas steam boiler. HTF, also known as organic heat carrier medium or hot oil, use as an intermediate heat transfer medium in the industrial heat exchange process has been more than 50 years of history. Based forced circulation design and development of once-through boiler. Typically coal, oil, gas fuel to oil as the medium, using a thermal oil circulation pump to force the liquid circulating medium, the heat energy to a heat transport device and then return again heated furnace, having obtained at low pressure high operating temperature, and can perform high-precision control of the working medium run. High system thermal efficiency, easy operation and maintenance, the closed-cycle heat to the atmosphere, the service life, the liquid or vapor phase delivery extended heating boiler. Gas steam boiler return three-coil design, the system is set up expansion of the water tank, provides low temperature heating. Using the coil structure, sufficient heating surface, expands sufficiently absorbed. Imports of low NOX burner, combustion, are environmentally friendly products. Boilers can use advanced touch-screen computer controller and digital computer controller automatic control. Having a thermostat, automatic ignition, and differential pressure, over-temperature, flame protection. Boiler manufacturing practices, in strict accordance with the relevant national standards. The use of gas steam boiler water quality requirements: Some users believe that as long as gas steam boiler water is held on it, the water quality indiscriminately. In fact, the use of water or gas steam boiler influential, small advice you to choose clean tap water. Because if there are impurities in the water, then the use of this device with impurities of water will have some impact. Impurities junction thick layer of scale on the inner wall of the gas steam boiler. The scale will gradually thickened over time, which will affect the efficiency of heat conduction when a thickness of accumulation is wasted energy. If the scale appears to be cleared, so the heat is concentrated in the scale easy to distribute.

Gas boiler szs 1 emergency shutdown procedures, if necessary emergency shutdown generally, when the boiler encounters one of the following, operation should be stopped in case of emergency; (1) allow the boiler steam pressure exceeds a safe pressure, fueling is stopped strengthen water supply, measures the wind pressure continues to rise. (2) boiler severe water shortages. Water meter can not see the water level. After being called water, the water level of sight. (3) When the severe water boilers, boiler water level is higher than the highest water level is visible, but the emission level not yet seen. (4) increase in boiler water, take other measures, the water level will continue to decline. (5) water supply device is turned off, standby equipment. (6) all water level gauge or invalid. (7) All the safety valve all the failures. (8) All all-off failure drain valve. (9) causing damage to the boiler pressure element (e.g., boiler tubes, etc.), or endanger the safety of the device. (10) boiler is a serious threat to other events and safety equipment. 2, natural gas boiler operation method szs immediate emergency stop operation of the controller, the boiler is off, closing the front of the boiler gas valve to stop the gas supply. The fire tube automatic steam boilers competent completely separated, opening the exhaust air valve or safety valve steam pressure. Due to lack of water, the boiler is not allowed into the boiler, the steam is not discharged to reduce pressure. No shortage of water, cold water can drain down alternate method, the water level remains complete accident should immediately stop the water supply, water reducing combustion (fire artificially changed into a small fire), play an open valve while opening the main steam pipe and the drain valve cylinder to prevent the steam to carry large amounts of water, water. In the shutdown process, the cooling rate of the furnace should not be too fast to avoid flue compression member and the expander is damaged suddenly cooled. 3, emergency shutdown processing method szs natural gas boiler in the case of emergency shutdown, due to the nature of the accident, the following may take a different approach: (1) rapid flame treatment emergency shutdown, the burner first station, and closing the valve flame gas supply is stopped after the cut valve, to maintain the water level is normal. (2) rapidly cooling the furnace or water if there is no water leakage during an emergency stop, the cooling time can be shortened to the boiler water and sanitation and reduce the pressure. When the boiler water temperature down to 80 degrees Celsius, boiler water can be discharged. If the boiler severe water shortages, the boiler can not cool quickly in the event of an outage. Non-water to the furnace, or explode. accident. (B) natural gas boiler shutdown SZS normal shutdown (complete shutdown, shutdown maintenance) procedures which can be used when needed repair or stop steam boiler. 1. If one of these faults, the leaders agreed, the boiler can be temporarily closed repair: bilge faucets, riveted joints leak, damaged tubes, the waterwall tubes, the heating tube, the flue gas contacts the drum, the head, off pipe insulation, water supply system, combustion system, a serious fail-safe accessories, in need of repair. 2, a temporary repair (or normal shutdown) the method of operation in order to stop the burner, for closing the valve. Boiler feed water to 2cm above the normal water level, to stop water supply, reduce the pressure. 3. Turn the main steam valve, open the traps, and steam boiler operation, reliable water separator. 4, boiler feed water close electric valve and manual valve, boiler feedwater reliable cutting. When the steam pressure drops to zero, the water can be supplied and discharged alternately, so that water is gradually cooled furnace, when the temperature drops to 50 degrees Celsius (or hand potshell touch feeling hot pan head), can be completely discharging furnace boiler water water . Before water, open the air valve on the boiler or lift safety valve. At this point, you can enter the furnace for inspection and repair. Cooling the furnace must be kept slow, non-violent cooling and damage to the boiler, the boiler can be stopped from the repair into the furnace, the cooling time is generally less than 24 hours. Close the furnace over 24 hours, shut off the gas supply valve at the regulator, and open the gas conduit pipe is responsible, in the exhaust gas pipeline.
