Dry: six gas-fired boiler safety procedures (hot water + steam) stage, the purchase of gas-fired boiler more and more users, in many industries, such as oil exploration, hospital disinfection, chemical production, wine feed, and so on. But many users initial contact with a gas boiler told us how to get started quickly boiler operation is not clear. First, all personnel must be familiar with the operation of the boiler boiler performance and safety knowledge, certificates; this non-job employees Never operate. Duty personnel should strictly follow the regulations, do a good job operating records and shift recording, the security situation should shift equipment and run tests, carried out. When the shift to check the boiler is intact. Second, purchasing, installing, or before the initial operation of the boiler, the boiler and safety accessories must conduct a comprehensive inspection, inspection and determined within the validity period to start. Third, Kai furnace ready to check the gas pressure is within the normal range of values, not too high or too low; check whether normal pump Sheung Shui, if unusual you need to open the purge valve until the Sheung Shui so far. Open the door of each section Water Supply System (including Sheung Shui before and after the festival gates pumps and boilers); check the water level, the water level should be in the normal position, the water level gauge, a water color need to plug in the open position, to prevent false water level, if missing water can be manually Sheung; check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob inspection control cabinet are in their normal position; steam boiler check valve is in the normally closed state, heat water boiler circulating pump outlet valve should be turned off; check water softening equipment is operating correctly, soft indicators of compliance with national standards. Fourth, Kai furnace run time 1, steam boilers Open the power to start the burner; check manholes, hand holes around the flange and valve leaks will be tightened, if there is still leakage after tightening occurs, you need to immediately stop maintenance furnace; l when the air pressure 0.05 ~ 0.1MPa, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; when the pressure was raised to 0.1 ~ 0.15MPa, rinsed trap gauge; pressure was raised to 0.3 MPa, the "fire load / small fire" knob to "fire" to strengthen the combustion; 2/3 when the air pressure was raised to the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; out when the drain valve when steam is completely close it; after all drain valve closed, slowly open the main valve to open, and then half a turn; "burner control" knob to "Auto"; level adjustment: adjusting the water level (according to the load manually when to start and stop the pump), low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; steam pressure adjustment: adjusting the combustion load in accordance with (manual adjustment fire / small fire) determines combustion conditions The flame color, smoke color determination condition atomisation air quantity and exhaust gas temperature observed concentration chimney, the best change in the combustion temperature to be adjusted according to the combustion. 2, start the circulation pump life hot water boiler price; startup burner; 15 minutes after start, "" fire load / small fire "spin-bit color button to" fire ";." Burner control "knob to" Auto "five, normal stop 1 furnace, hot water boilers' fire load / small fire "knob to" small fire "; off the burner; close the fuel supply valve; closing dampers; boiler after the temperature dropped to 50 ℃, the pump outlet valve closing cycle ; .2 circulation pump is stopped, the position of the steam boiler "fire load / small fire"; Close combustor; steam pressure drop when the sewage to 0.05-0.1MPA; closing the main steam valve; manual replenishment to the higher level; Close valve; Close supply valve combustion; closed dampers; six off the main power, an emergency shutdown, the steam boiler main steam valve closed; off the main power; 2, boiler water boiler inlet and outlet valve closed; opening the emergency valve and the emergency discharge replenishment valve; off the main power switch; notification superiors.
Check before 1 life hot water boiler price operation, including the use of internal inspection and boiler ready. 2, stove and flue inspection, stove and chimney soot and debris should be removed. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. To adjust the door and the flue duct, the door must be complete and tight, the switch must be flexible, open and close indication must be accurate. 3, boiler accessories conduct inspections of safety accessories in good condition; if the plug rotating flexible, convenient; all kinds of instruments and controls should be complete, good, clean. After examination by the pressure gauge cocks should be in working condition. 4, check Zidongkongzhi system. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. 5, check the auxiliary equipment. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 6, the combustion device checks to see if the combustion device is in good condition; for mechanical transmission, coal handling system, ballast system, steering normal test; safety spring gearbox lubrication should be properly compacted and; Crosscut indicate the correct scale. Iron Eagle neatly intact, complete ballast plate, flexible movement. 7, the auxiliary heating surface inspection, check the auxiliary device (fan, water pump, etc.) is firmly connected to the coupling; v-belts suitably loose; good enough lubricating oil; cooling water flow. After the check, the safety shield is mounted, a separate test run, the idle current note.
