SZS high efficiency gas fired water tube boiler
A general increase in the standard of environmental governance, Huzhou City, Zhejiang Province closely follow the direction of development policy, will gradually phase out coal-fired szs high efficiency fired water tube boilers or adapted for the gas boiler. According to statistics, Huzhou City Nanxun five years has eliminated nearly 3,000 small coal-fired boiler, saving 720,000 tons of coal resources.
Remediation process, district departments form a joint working group, while the seizure of small boilers, while helping business transformation. Behind the small boiler one Taiwan "puff", representing a small wood processing, printing and dyeing, textile and a number of high pollution and high energy consumption enterprises. They only destroyed the visual landscape, but also pollutes the lies to be the region's transformation and upgrading process must break the "pots and pans."
Huzhou referred morning Decoration Co., the person in charge mentioned: "In the past coal-fired boiler pollution does not say, but heating is not stable, press only a day after more than 300 wood boiler replacement, productivity improved significantly, now at least a day. can be pressed more than 500. "this shows once production efficiency improvement, enterprise back to the speed can be increased to a year.
After the disappearance of small boilers, or to benefit a lot of people around. "Our village is known for the production and processing of small wood gathering, the family opened the window every morning before'll see a row of chimneys in the distance 'spit black smoke'. Now grinding temperature, steam generator replaced the original coal boiler, surrounding environment has improved significantly. "FEATURE before the flood who lives in the village of Lao Shi sincerely laments.
Improvement in the area of active removal of small boilers companies subsidies, also made detailed provisions on subsidy amount of different types of boilers. Meanwhile, the district has built South Lake thermoelectric, thermoelectric GCL, Guodian three cogeneration projects, the laying of 200 km of heating pipe network, and the end of last year to achieve full coverage of central heating.
The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC szs high efficiency fired water tube boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.
(2) major components: the gas burner 5 is constructed of the following system components: 1, the function that the air supply system, air supply system into the wind speed a certain amount of air to the combustion chamber, its main components are: a housing, the fan motor, fan impeller, air guns fire tube, damper controller, damper baffle, a cam adjusting mechanism diffuser plate. 2, the ignition system functions in that the ignition system ignites a mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. 3, system monitoring function monitoring system is to ensure that the burner safe and stable operation, the main components are flame detectors, pressure monitors, temperature monitors and the like. 4, functions of the fuel system of the fuel system is to ensure that the desired fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The gas burner mainly a filter, pressure regulator, solenoid valve, and then firing solenoid valve, the fuel valve. 5, electronic control system electronic control system command center and the focal the above system, the primary control element is a control box, with different programmer for different burners, the common programmer has: LFL series, the LAL series, LOA series, LGB series, the main difference is the time of each different program steps. 1, AC 220V power supply is turned on, the buzzer beeps once. 2, press the start button, the buzzer sounds, power controller, the LCD display is opened. At this time, the controller is in standby. 3, the controller opens, through the keyboard operator can enter the running state (open furnace), out of service state (shutdown), the pump manually set the time, access to the recording operation of the alarm and the like. Fireman who usually just press the start key to start the oven, press the stop button shutdown, is very simple. 4, press the start button, to enter the running state, the controller controls the start and stop of the burner according state szs high efficiency fired water tube boiler water temperature, controlling start and stop the pump in accordance with the temperature of boiler water level or state. 5, press Stop key to exit the operating state, the controller closes the burner and the pump (with the exception of pump delay). 6, in the standby state or alarm press the stop button, the LCD display is turned off, the controller off. 7, manually operated pump device selection key press, the pump mark blinks to indicate that the selected pump operation. Proceed as + key auto / manual switch (when the pump is in the manual mode, the pump below the graphic display flag Manual); button can also be provided to manually activate or deactivate the pump (pump case immediately into the manual mode). Press the device selection key to exit the pump operation.
Energy-saving measures and methods of industrial szs high efficiency fired water tube 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.
