Gas Fired Water Tube Hot Water Boiler

Gas Fired Water Tube Hot Water Boiler

Gas-fired steam boilers and pressure fired water tube hot water boiler has what a difference, the most critical is that goods difference: pressure hot water boiler production part of the standard high-temperature water; the production of gas steam boiler is part of the standard steam. Second, the auxiliary little difference: like supporting pressure hot water boiler water circulating pump, does not need gas steam boiler; gas steam boiler water level gauge support, do not need pressure hot water boiler; gas cylinder steam boiler supporting points, pressure hot water boiler with tank; Third, the production boilers, boiler installation, a boiler, a steam boiler safety of the gas stringent requirements. Fourth, the key difference is the use of gas boilers steam production is saturated standard high pressure gas for power generation, tie-dye, medical and other fields, is due to the production of saturated steam, pressure equipment is therefore, a boiler and the boiler installation must meet Compliant pressure hot water boiler is the production of high temperature water, not a pressure equipment. How to gas steam boiler blowdown gas boilers | oil boiler | Environmental Equipment Co. steam boiler (1) open inside discharge water valve; (2) slow external open blowdown valve, and the discharge duct for warming; (3) back and forth on the exterior from the opening and closing of the blowdown valve, the buffer boiler dirt stains, so that the dirt is discharged as water stains; (4) the inner blowdown valve closed, the waste water stored between the two valves drained water; (5) external blowdown valve closed, to complete the discharge.

Fangkuai boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. (6) what are the main factors affecting the wear rate? 1 flue gas, 2 flow rate of the material, 2 particle size of the material in the flue gas, and 3 the surface shape of the worn component. The velocity of air flow is the most important factor affecting the relative direction of motion of the worn material and the wear is proportional to the third power of the velocity. 7. Why should the bed temperature be controlled between 850 and 950? 1 the ash will not melt at this temperature, thus reducing the risk of slagging 2. Higher desulfurization efficiency 3 less nitride gas in combustion gas at this temperature 4 Alkali metal in coal does not sublimate at this temperature, which can reduce slagging on the heating surface. 8, why do you have to blow the boiler pipe? Some equipment in boiler steam-water system, such as dewarming water, start-up bypass, superheater, reheater pipeline system, are not suitable for chemical cleaning due to structure, material, arrangement and other reasons. So it is necessary to use the physical method to remove the residual debris before the new boiler is put into operation, so the steam produced by this furnace is used to blow the steam-water system and equipment. 9, what are the common methods of boiler maintenance? (1) Wet protection: there are diammonium method, ammonia method, maintain feed water pressure method, steam heating method, alkali liquefaction method, trisodium phosphate and nitrous acid mixed solution protection method; (2) dry protection: there are drying method (with pressure discharge) and desiccant method. 10, which causes the deterioration of steam quality (steam pollution)? (1) steam with water. The boiler's feedwater contains impurities. The feed water is heated into steam after entering the boiler, and most impurities are transferred into the boiler water. So many cycles, the impurity concentration in the boiler water becomes higher and higher. Furnace water containing high concentrations of impurities is carried by saturated steam, which is called steam carrying water, which is called mechanical carrying. The first reason for steam pollution. (2) Steam-soluble salt. At higher working pressure, steam can dissolve some salts, which is called selective transport, which is the second reason of steam pollution.

Electric steam 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.
