200hp water tube boiler fire gas
Water temperature increase impact on the thermal efficiency of the 200hp water tube boiler fire? A: The water temperature to improve thermal efficiency of the boiler can be divided into two cases to discuss. The first case, assuming constant evaporation boiler. When the water temperature increase, due to the economizer heat transfer temperature difference is reduced, reducing heat absorption, enhance the tobacco temperature economizer, air preheater temperature and pressure increase, increase heat transfer, the hot air temperature increased slightly, smoke the temperature rises, so that boiler efficiency is lowered. However, after the water temperature increase, increase in the heat for evaporating the evaporation increases. In order to maintain unchanged the amount of evaporation, it is necessary to reduce the amount of fuel, which makes the exhaust gas temperature is lowered to improve the thermal efficiency of the boiler. Because of these two factors on the thermal efficiency of the boiler roughly, therefore, when the constant holding evaporation boiler, the thermal efficiency of the boiler feed water temperature increase substantially unchanged. The second case, assuming that the same amount of fuel. After the water temperature increase, decrease temperature and pressure economizer, economizer flue gas temperature, increasing the air preheater heat absorption, the exhaust gas temperature rises, reduce the heat efficiency of the boiler. Since the hot air temperature is increased, the furnace temperature increases, water wall heat absorption increases. After the water temperature increase, the heat for increasing the temperature is reduced, while increasing the amount of heat for evaporation. Therefore, the water temperature increase, if the fuel quantity constant, the increased evaporation, but the thermal efficiency is lowered. To sum up, raise water temperature, evaporation is kept constant regardless of the amount of fuel still remains the same, we can not improve boiler efficiency. However, to improve the water temperature, it does improve the thermal efficiency of the plant cycle, thereby reducing the coal consumption.
How much do you know about product performance vertical steam 200hp water tube boiler fire? Vertical steam boiler Product Description: vertical steam boiler, furnace various comprehensive domestic technological transformation, absorbing international advanced technology, the introduction of a new generation of horizontal oil (gas) boiler, product design has been applied for patent, pot head by a shell , boiler shell, U-ring composition, furnace head, lateral pipe, tube flying rocks. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Combustion boiler using conventional techniques, the medium input from the door opening, an upper portion of the combustion grate, the furnace flue gas through multiple lateral flushing water, the carbon black and the rising process of fine soot particles are multilayer tube blockage, reducing the operating speed. Falls on the grate is re-smoke combustion, combustion flue gas discharged to the atmosphere through a stack. Performance: placed on top of the hearth grate boiler U-shaped scraps, the direct flame furnace and flush mounted tube furnace bending cylinder; structural characteristics of the boiler is to bend the vertical inner elbow installed in the furnace, increasing the radiation heating area. 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. But because the degree of water-cooled furnace, the furnace temperature is reduced accordingly, generally applicable to coal burning quality. If you add the refractory bricks in the furnace, the coal may be lean combustion at higher temperature in the furnace. Preferably water cycle, each portion of the flue gas scrubber are cooled by, unitary structure having a good elasticity.
From March 18 to start, Lujiang County, Anhui Province north of the Market Authority on the area of internal security to carry out a special inspection of 200hp water tube boiler fire pressure boiler; To ensure the safe operation of this special equipment, complete elimination of security risks.
The inspection mainly troubleshoot and eliminate hidden dangers in the management and operation of the boiler links exist, focus on examination of whether to establish safety management systems and procedures; whether to set security management or part-time security management staffing; whether workers with valid work certificate for employment; boiler operating records, inspection records and shift recording is complete; if the boiler for the use of registration; whether the inspection within the validity period; check valve is within the validity period, the pressure gauge whether the test within the validity period. Up to now, law enforcement officers dispatched 27 people, focus on examination of 12 times the focus of special equipment supervision units, hospitals, schools, boiler 20 times, do not meet the specified use in accordance with the boiler "Special Equipment Safety Law of People's Republic of China." requirements, issued a supervision instructions, requires immediate rectification unit, for there is no regular inspection of boilers or unqualified, shall not be put to use.
Electric steam 200hp water tube boiler fire 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.
