gas fired chain grate hot water steam boiler
AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing fired chain grate hot water steam boiler fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.
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.
Hot water boiler fuel classified according to different hot water boiler fuel can be divided according to different electric hot water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; pressure can be divided according to whether pressure hot water boiler and two kinds of pressure hot water boiler, we usually call "hot water boiler" refers to the atmospheric pressure hot water boiler, due to its safe operation, people bathing or heating largely adopted this pressure hot water boiler. Type water tube boiler assembly controller computer, all the functions are stored on a smart chip realize intelligent boiler, digital, automatic, user-friendly, intelligent control of boiler water, water reaches the automatic stop heating; screen large font temperature, boiler water temperature at a glance. 2, boiler water temperature can be freely set from 10 deg.] C to 100 deg.] C, the boiler can supply both hot water bath can provide water for drinking, may be a dual oven. 3, the top of the furnace through the air opening is provided, the boiler is in an unpressurised state, there is no danger of explosion, while the machine is equipped with thermal protection (ultra-high-temperature furnace during the heating tube buzzer alarm and automatically stop working, secondary overheat protection (boiler housing temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry water protection (when the furnace is less than the water level is very low, the boiler is stopped and an alarm buzzer) and a number of security. drum such drum type hot water boiler hot water boiler, early mostly modified from a fired chain grate hot water steam boiler made, which in the case of boiler water within a boiler of natural circulation. in order to ensure safe and reliable boiler water cycle, the boiler requires to have a certain height, so these larger boilers, steel consumption, and the cost is relatively increased. However, since this type of boiler capacity and can maintain the natural water cycle, when the system pump is suddenly stopped, the pot can be effectively prevented vaporization of water. it is also for this reason, natural circulating hot water boiler in our rapid development.
When gas boiler outage, we should not panic, there must be the order of the operation, shut off the gas boiler. 1, the normal shutdown sequence, check the gas fired boiler fuel, gas, water shutdown valve meets the requirements; 2, off gas, coal boiler blowdown valve to prevent the surface of boiler drum cause other problems; 3, quickly closing the main steam valve prevent dehydration gas fired boiler drum; 4, close the supply valve and deaerator power switch and gas valve.
