2-20T Automatic Industrial Gas Fired Steam Boiler

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.

"Euromonitor" closed series of boiler condensate recovery system, the condensed water directly into the boiler temperature, with three-pass boiler air preheater + + economizer, full use of the flue gas heat recovery and then the temperature condensate from the source use, reducing energy waste and significant cost savings for businesses, the effect is immediate.

biomass/coal fired 2-20t automatic industrial fired steam boiler for tofu machine

Our biomass/coal chain grate boiler in structural design, relative to the larger space of the traditional boiler hearth, while the layout of a secondary air, a reasonable composition of the aerodynamic field, to ensure that flue gas in the furnace residence time to avoid the tiny carbon particles are taken out of the furnace, So that a large number of volatile components precipitated instantly burning biomass fuel combustion.

3 macrotaxonomy 2-20t automatic industrial fired steam boiler steam boiler fuel can be divided in accordance with the electric steam boiler, steam boiler fuel, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler mostly small single, double return the vertical structure, large steam boilers and more horizontal structure of three return. Vertical fuel gas steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost. Horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving and economical use. Waveform threaded pipe and furnace structure, not only improves the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.
