Flue gas condensation in aqueous industrial industrial boiler machine 10t moldavias and industrial boiler flue gas condensing position of the condensation water and the condensed position 1, the steam boiler flue gas dew point of industrial coagulation process means starts to condense water vapor in the flue gas the temperature, condenses into water vapor when the temperature is lower than the dew point temperature. Without considering the impact of the acid gas, flue gas dew point increases to increase, increasing the concentration of water vapor in the flue gas, increases as the excess air ratio is reduced. Formation of condensation water depends on the temperature distribution of the flow cross-section. For example, when the flue gas through the pipe, the core flow temperature maximum, minimum wall temperature. When the wall temperature is higher than the dew point, no condensate water, when the wall temperature below the dew point temperature of the core flow above the dew point. When the core flow temperature below the dew point, the air flow condensing section. Number of smoke generated condensed water is affected by many factors, such as size, fuel, exhaust gas temperature, the air ratio, the structure of the boiler heat transfer surfaces and the like. 2, boiler condensate condensed gas industry position in the boiler in order to improve the thermal efficiency of the boiler, efficient recovery of the latent heat of the flue gas steam gasification boiler with a condenser and is widely used in industrial heating systems, i.e., by installation absorb latent heat of water vapor in the flue gas. Saving device and a condenser. At design conditions, the flue gas temperature at the outlet of the boiler body above the water vapor dew point temperature, water vapor in the flue gas mainly in the condenser and economizer. Since the high-temperature steam in the boiler, the exhaust gas temperature before the flue gas enters the economizer is generally higher than the dew point, so a small amount of water vapor generated by the boiler condensate, hot water boilers and boiler due to low temperature, return water temperature lower than the annealing furnace smoke gas dew point temperature. Winter start or low load operation, leading to the exhaust gas temperature below the dew point temperature. Thus, prior to entering the economizer, some of the water vapor in the flue gas of the boiler tail heating surface condenses into water. The above analysis, generating the main part of the condensed gas are in industrial boiler economizer heating surface and the boiler, and thus boiler economizer outlet gas industry are usually set in a drain nozzle of the heating surface.
What harm grate steam industrial boiler machine 10t moldavia slagging cause? Steam boiler slagging will not only increase the workload of boiler operation and maintenance and overhaul, seriously endangering the safety and economic operation, but also may force the furnace to reduce load operation even forced shutdown. Slagging itself is a complex physical and chemical processes as well as automatically increasing features, once the boiler slagging occurs, since the thermal resistance of the heat transfer deterioration of the slag layer, the slag layer in the furnace and the die temperature are elevated surface temperatures, coupled with slag layer surface roughness, adhesion of slag particles up easier, slagging process results will be intensified. Following a brief set out the harm caused by steam boiler slagging. 1, after the heating surface slag, thermal resistance will increase, decrease heat transfer, reduced working fluid to absorb heat, the exhaust gas temperature increases, to increase heat losses, boiler efficiency is lowered. To maintain the normal operation of the boiler, while increasing the amount of fuel flow rate must be correspondingly increased, which makes the feed, increased loading draft fan, increased auxiliary power, therefore, the economy of slagging steam boiler significantly reduced. 2, when the heating surface slag, in order to maintain the normal operation of the steam boiler, the air flow must be increased. If the ventilation capacity is limited, together with the flue gas channel tends to slagging partially plugged, the flue gas resistance increases, it is difficult to increase the fan flow, forced to down-load operation. 3, the heating surface slagging furnace exit gas temperature rise, resulting in overheating temperatures, combined with thermal excursions caused by slag, Superheater easily cause damage. In this case in order to maintain the temperature and overheating protection reheater, the need to limit movement of the load. 4, slagging combustor nozzle, the outlet stream to change the structure of the burner, so that the condition of the Aerodynamic damaged, affect the combustion process. Severe slagging spout while being blocked, the steam boiler had to down load operation or forced shutdown. 5, water wall slagging, so that it will be unevenly heated parts, adversely affect the safety and control of the flow of hot water wall deviation natural circulation water circulation, may lead to destruction of the waterwall tubes.
2018, the Group's trade unions lead the effort and hard work. In June - July, the group took part in the front-line staff union workers vocational skills competition in Henan welders trials, employee segment slowly rise to become the dark horse on the field, won the "female bonding child" in the world, made in Anyang City fifty-one Heroine Heroine number of honorary titles. 2018, the group led everyone happy union work. "Division with only" mechanism in the company to bear fruit, youth workers get training and skills gradually improved. Rich in the traditional sense of "apprentice ceremony" making our "division with only" job skills training to become a shining Anyang City workers "business card." On the municipal key tournament organized by the company, young welder you compete to catch the top ten among them are four outstanding students under the "division with only" mechanism generated.
Especially when using a heating industrial boiler machine 10t moldavia, not less than two, which for some reason when one stops, the remaining boiler heat transfer design should meet the requirements of the owners guarantee for heat.
