Hot Water Gas Fired Boiler

Hot Water Gas Fired Boiler

Process safety valve check valve gas steam hot water fired boiler is one of the three safety accessories gas steam boiler, when the boiler pressure is too high, the pressure relief valve will automatically exhaust, gas steam boiler is the important safety equipment . The case of a new installation, overhaul, lack of consumer safety valve shutdown and restart more than three consecutive months, have had to re-check safety valve, safety valve to ensure accurate and reliable by the company safety officer, boiler technician, run operators, maintenance personnel together with the completion of the adjustment. Valve adjustment procedure is as follows: 1, the steam boiler when the gas vapor pressure close to the operating pressure of the safety valve, and retest check valve to the air motor exhaust, drainage accident flexibility and reliability of the electric valve, and the panel reinspection situ pressure gauge, the water level of accuracy, such as failure, not allowed to heat the school. 2, ready to call and check the quality of communication tools, a signal indicating whether the good. 3, adjust the safety valves, boiler pressure should be kept stable, pay attention to monitoring gas steam boiler drum level, and maintain normal. 4, steam boiler safety valve to adjust the pressure gauge in place of instructions shall prevail. If necessary using 0.4 or more for the accuracy of the gauge. 5, adjust the safety valve should be carried out only by descending. It should checksum gas steam boiler tuning high pressure safety valve, after the school seizure of the entire set of low pressure relief valve. 6, the following should be in the 0.3MPa, the movement preventing measures must do a good job of setting relatively low pressure steam boiler safety valve safety valve before adjusting. 7, by combustion, and exhaust steam adjust the degree of opening to the air slowly and smoothly up to the required setting pressure. 8, when the gas pressure steam boiler safety valve set pressure to rise if action is normal, then the action and reseating pressure values ​​recorded. If action is not correct or not action should be immediately opened to the air exhaust valve, while the combustion boiler weakened, stop boost, and buck 0.3MPa or less, re-adjust the boiler technician as required by maintenance personnel, until the compliance date. (Lead or lag 0.05MPa action is normal). 9, after the completion valve to adjust gas steam boiler, boiler 0.3MPa or less down to the lifting device and can be installed and fastened to the protective cover, a braking measure required under check valve removal, then Articles 7, 8 verify until all required safety valve calibration check is completed. 10, the safety valve to adjust the gas boiler, check the results recorded in the "safety valve to adjust the recording Visa" within the participants should verify the signatures and Internet safety valve input to the corresponding data in the ledger. During operation gas steam boiler, not only to regularly check on the safety valve, at the same time, we must regularly monitor boiler inspection to ensure that the boiler fully meet the safety requirements!

The onset of winter, to ensure the safe operation of heating hot water fired boilers, recently, Fengning, Hebei Province Market Authority to schools, hospitals, residential, hotels, enterprises and other crowded places as the focus, to carry out security checks special action winter heating boiler.

The boiler safety inspection to check whether the action is mainly for the use of registration certificate, whether or not the maintenance, overhaul and maintenance, boiler safety accessories are conducted periodic inspection; the use of units to establish whether the relevant rules and regulations and safety rules, file information is complete, run record is perfect; whether the unit is equipped with the required safety management, whether fireman and water treatment personnel certificates; whether developed special equipment safety measures and emergency rescue plan, with related emergency rescue equipment.

Through this inspection, supervision and special equipment unit firmly establish the safety production of "red line consciousness" to strengthen the routine inspection of the unit and boiler maintenance work in a timely manner to eliminate potential accidents.

Electric steam hot water fired boiler flue of accumulating a certain amount of soot how to deal with? Electric steam boiler furnace cleaning backpass long-term non-stop, accumulating a certain amount of soot or carbon black. Solution: When the temperature drops below the flue 50 ℃, check before entering the flue tail heating surface, and should completely remove the flue soot. If not burning, can be re-started ignition; if burning, should be replaced, repaired burning member; large negative pressure of the combustion chamber, so that gas will be no time to burn into the electric steam boiler tail. Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C and more stable during 1h openable inspection hole inspection, after checking element determines the source of fire, the ventilation fans before starting. When shutdown or electric steam boiler fire, air gun valve is not closed. Solution: strengthen the electric steam boiler feed water and turn on the water, open the valve or economizer recirculation tube to protect the economizer being burnt; lower start, the furnace temperature during shutdown, unburned fuel in the furnace . Solution: fire extinguishing devices immediately into steam, carbon dioxide or other fire extinguishing devices; burn improperly adjusted, with insufficient wind or with the wind unreasonable. Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan.

Note matters including gas hot water fired boiler gas water boiler, gas hot water boiler, gas steam boiler operation gas boiler, gas hot water boiler which is also known as gas heating boilers and gas boilers bath, as the name suggests refers to the gas boiler fuel gas boilers, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. Note that the operation of the gas boiler gas boiler valve matter is very common to use an apparatus of the plant, under normal circumstances the handle, thorium clockwise rotation of the handwheel is turned off a predetermined direction, the rotation is defined as counterclockwise opening direction. But before the operation should focus on some check valve opening and closing flag after the operation. The following gas boiler manufacturers of small series simply to introduce the next gas boiler ajar fast opening valve operation Note: gas boiler slowly open the valve to open, slightly open after the quick opening valve, preheat the pipe and then fully open. For better results the sewage, can switch several quick open valve. After discharge, turn off the quick opening valve, then slowly open the valve is closed, and finally open about fast opening valve between two valves to put water in the net.
