Different natural gas boiler steam boiler energy-saving measures as well as gas-fired boiler with environmental issues become more critical, more and more people are concerned about the importance of the environment for our development. Today, gas steam boilers in industrial production is very common, how to reduce the energy consumption of gas steam boilers, which we have been explored. We can take the following measures in natural gas steam boiler operation for energy. 1, the amount of steam needed for industrial production of a reasonable choice, and the number of the rated power station boiler steam boiler gas, in both cases the higher the degree of matching with the actual exhaust gas loss is smaller, the obvious energy saving. 2, the fuel in contact with air: fuel amount so that an appropriate amount of air and the optimum composition ratio of combustion, this would both improve fuel combustion efficiency and reducing emissions of polluting gases, energy to achieve the dual goals. 3, reducing the temperature of the exhaust gas steam boiler: the temperature of the boiler flue gas to reduce the effective use of exhaust heat generated in general, the efficiency of the boiler used is 85-88%, the exhaust gas temperature is 220-230 ℃. If the setting of energy-using the exhaust heat or the like, the exhaust gas temperature falls to 140-150 deg.] C, the boiler efficiency can be increased to 90-93%. 4, recycle heat from the boiler blowdown water: water using continuous blowdown heat by heat exchange, in addition to improving water temperature itching water to achieve energy saving gas steam boiler. At the same time, measures energy-saving gas steam boiler can also be reasonably recovered condensate heating system, and the heat of the condensate water recycling. It is different from the gas boiler and gas boiler: 1. Gas circulating fluidized bed combustion boiler coal by crushing device by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx discharged from the flue gas the atmosphere, pollute the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions relative gas boiler gas boiler, SO3, NOx is much less. 3. Usually ventilation negative pressure combustion gas boiler, the combustion process is to group together to complete the mating with the mating blower and induced draft fan, the coal combustion process, requires a lot of air and the furnace wall due to the leakage of the flue, the excess air coefficient of up to between 2.1-2.5. Gas boiler combustion slightly positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion flue and the furnace wall, the flue outlet air ratio operation may 1.05-1.2.4. Fuel explosive gas boiler combustion safety, the furnace explosion hazard unlikely to occur. The gas-fired boiler in the explosive concentration limits encountered fire will explode. More dangerous. 5. Gas boiler control difficult due to coal boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to the operating parameters of the boiler load is large. Less impact on the factors of the gas boiler, the burner may be adjusted according to the size of the load valve, easy to achieve automatic control.
Hot water boiler for users to solve the "coal" urgent at present, energy conservation and building sustainable economic model has become a national priority, but only our coal utilization hovering around 30%, far below the 78 % of the international average. 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. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass boiler steam boiler, biomass hot water boiler, biomass oil furnace. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees Therefore, improving the utilization of coal combustion has become essential. Currently, coal-fired hot water boiler control system to achieve precise control and real-time monitoring. By controlling the water temperature, the fan speed to achieve a controlled, to ensure the stable combustion furnace pressure and coal, which saves coal, but also to ensure safety. Industrial production in the boiler and heating primary energy into secondary energy of important equipment, has been widely used in industrial production and daily life. Coal-fired hot water boiler control scheme is reasonable and convenient way to monitor, steady state operation, the whole process of thoughtful service, users get a good feedback. I believe in the future, coal-fired hot water boiler intelligent control scheme can serve a wider field of industrial production, as well as hotels, schools, hotels, residential heating, bath, hot water and other fields, coal cost savings for users, improve combustion efficiency, ensure the safe operation provide a solid guarantee. Completely solve the problem of long-term accumulation of the user, the water temperature stable. Water temperature set by the ambient temperature, grate speed difference adjustment according to the actual water temperature and the set temperature of the water, i.e. adjusting the amount of coal boiler, to ensure the stability of the water temperature. Outstanding energy saving. Grate speed changes to the feedforward signal, in conjunction with flue gas oxygen content signal or the furnace temperature, blower speed control using the PID algorithm, to ensure full combustion of the coal, to improve the utilization of coal, reduce emissions of harmful substances. Excellent safety performance. To change the fan speed as a feedforward signal, the PID control calculation and induced draft fan speed according to the furnace pressure value, to ensure the stability of the furnace pressure. This paper introduces a control algorithm based on the level of intelligence of the new big jump lag PID. After control of embodiment, given a certain waiting time to observe the effect, and to determine whether further embodiment control, multi-parameter input and multiple output control mode based on performance parameters.
