low nox condensing horizontal gas fired steam boiler price

Electric low nox condensing horizontal fired steam boiler price of the heating process due to elevated water temperature within electric steam boiler, heating and evaporation of the bubble surface of the metal wall temperature begins to rise at any time. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Since the bubble greater wall thickness, in the electric boiler of the heating process, the thermal stress is a major problem, it is necessary for the thermal expansion of the bubble temperature and thermal stress study. At the same time, also considering the overall thermal expansion problems, especially an electrical heating surface tube steam boiler, since the thin wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused. In the process of generating steam and processing the thermoelectric pressure steam boiler, when the temperature is higher than the outer wall temperature of the inner wall, the upper wall at a temperature above the wall temperature, the wall thickness and the temperature difference between the upper and lower walls of the bubble there is a temperature difference, i.e., bubble the inner wall temperature above the temperature of the outer wall, the wall temperature is higher than the wall temperature, the temperature difference between the thickness of the bubble exists in the thickness direction, the upper and lower walls of the larger temperature difference between the bubble, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the wall temperature. In order to prevent excessive thermal stress, it is necessary to gradually increase the pressure of the boiler. In the process of electric spark and boost steam boiler, the steam parameters of the boiler components, water and conditions are changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange a variety of instruments to monitor closely the instruction of professional change. Within the normal allowable range, but also the reliability and safety of various instruments, valves and other components was evaluated by adjusting the process parameters pressure, temperature, water, etc., in order to fully guarantee the security of the electric steam boiler stable operation. The higher the electric steam boiler pressure, the higher the energy, the corresponding steam plant, pipes and valves can withstand the pressure will increase, which also makes the maintenance and protection requirements of the steam boiler is relatively high. In the production and transportation, and the ratio of heat loss will increase the share of the steam.

Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.

Cause of abnormal gas low nox condensing horizontal fired steam boiler price stall phenomenon gas steam boiler and treatment of non-normal stalling reason, phenomena and treatment 2013-1-139: 17: 30 to cause a flameout: 1, or the operation of the auxiliary trip power outage. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, volatile or low calorific value gas. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart.
