Factors affecting energy saving and environmental protection of heating boilers
Boiler thermal efficiency Thermal efficiency is one of the comprehensive indicators to measure the performance of boilers. The thermal efficiency of heating boilers can be optimized through various ways, which can effectively promote the energy saving of heating boilers. The heating boiler is essentially a device that converts energy, and among the factors that affect its energy conservation and environmental protection, the thermal efficiency index can concentrate on the comprehensive energy, which is of great significance for the energy-saving evaluation of the heating boiler. The reasons for the low thermal efficiency of the heating boiler are abundant, including the boiler operator not strictly following the operating procedures, the technical level is insufficient, the furnace design is unreasonable, the boiler is overloaded, and the daily maintenance and overhaul of the boiler is neglected, which directly leads to The energy consumption of the boiler is getting larger and larger, the heating efficiency is gradually decreasing, and the operation of the boiler is also in an unstable state, which causes the energy to be effectively used or a large amount of energy waste.
Boiler slag carbon content
The carbon content of the heating boiler slag is another important factor affecting the energy saving of the heating boiler. The carbon content of the boiler slag is too high, generally the coal energy is not fully burned, and the cause of the situation can be divided into excessive coal combustion, excessive coal particle size, low furnace temperature, unreasonable boiler operating parameters, etc. several aspects. a) The boiler operating parameters are unreasonable. This situation will lead to insufficient O2 in coal combustion, insufficient temperature, and inappropriate coal-fire ratio, resulting in incomplete combustion. In this case, coal is also discharged into the furnace according to the general procedure, and a large amount of coal is wasted. To limit the energy saving of the heating boiler, the operating parameters should be adjusted to achieve the goal of reducing the carbon content of the slag; b) the coal particle size is too large. Under normal circumstances, the coal particle size is too large, because the burning time is short, only the surface coal is burned, and the deep coal is not fully burned, which is not conducive to the environmental protection of the heating boiler, so it is necessary to fully burn the coal in the heating boiler, so that Effectively promotes efficient operation of the boiler; c) burns coal moisture. Coal-fired water will affect the combustion of coal, or have a greater impact on the performance of heat, but also have a certain impact on the operation of the heating boiler; d) the furnace temperature is too low. The furnace temperature is too low, so that the heating boiler cannot perform energy-saving operation normally.
Boiler exhaust temperature
The heating boiler has a certain heat loss during the operation, which can directly cause a large amount of energy consumption and waste. Among them, the heat loss of exhaust gas is the main component of the heat loss of boiler heat. The main cause of the heat loss of the exhaust gas is that the exhaust gas temperature is higher than the outside air temperature, which leads to heat loss. Therefore, it is necessary to strictly control the temperature of the exhaust gas of the heating boiler to keep the boiler exhaust gas temperature at a fixed level. Control temperature range. The temperature of the exhaust gas needs to be moderate. If the exhaust gas temperature is too low, it is necessary to strengthen the heating surface of the boiler tail. Consumption of more energy for this measure will increase the cost of the heating boiler when operating, such as a higher exhaust gas temperature. The ventilation resistance will be increased, and the induced draft fan needs more power to conduct the air, which increases the consumption of electric energy, and the energy saving effect of the heating boiler is greatly limited. Therefore, in order to achieve energy saving and environmental protection of the heating boiler and reduce the consumption and waste of the Ministry of Energy, it is necessary to strictly control the temperature of the exhaust of the heating boiler, and the determination of various factors needs to be determined after economic accounting, including the heat of exhausting smoke. Loss, metal consumption of the heated surface of the tail, and smoke dew point reduce energy consumption in all aspects.
Energy saving and environmental protection technology
Set layered coal feeder
To reduce the amount of coal burned in coal plants, the stratified coal feeder can be fully utilized. The stratified coal feeding device can effectively save the coal consumption and make the heating boiler achieve the goal of environmental protection and energy saving. In modern workers' boilers, gravity-displacement stratified coal feeding devices are generally used to improve the uniformity of coal particle size entering the coal hopper, and then through the screening and classification of the stratified device, the coal is strictly in accordance with its particle size when entering the furnace. Reasonable coal seam arrangement can effectively improve the burning rate, ensure good combustion conditions, reduce the carbon content of the ash, and optimize the boiler thermal efficiency. Applying this measure to practice, the survey shows that the boiler combustion efficiency will increase by about 13%, the carbon content of the boiler will decrease by about 15%, and the furnace temperature will increase by about 150 °C, which greatly saves the need for heating. Coal.
Closely monitor the operating status of the heating boiler
Closely monitoring the operating state of the heating boiler and adjusting the state according to the status is not only one of the effective ways to improve the operating efficiency of the heating boiler, but also promotes the environmental protection of the heating boiler. To closely monitor the operation of the heating boiler, firstly, it is necessary to install the instrument in the dispersed boiler room and carry out inspection. The centralized boiler room needs to be equipped with a microcomputer to carry out monitoring. According to the situation, different adjustment measures are implemented for different boiler rooms to ensure the stability and high efficiency of the monitoring boiler. run. This measure has certain requirements for the boiler room management personnel. It is necessary for the management personnel to grasp the outdoor air temperature conditions of the boiler while monitoring the operation of the heating boiler, accurately calculate the heating index, comprehensively grasp the operating state of the heating boiler, and then determine the supply according to the situation. The elements such as heat, coal consumption, and time of returning water temperature accurately grasp the temperature time of the heating boiler. In addition, the operator should adopt the rated heating according to the heating index and adjust it according to the actual needs.
Optimize the adjustment method of boiler blower induced draft fan
Changing the adjustment mode of boiler drum and induced draft fan is a necessary link to realize energy saving and environmental protection of heating boilers. The general boiler blower mainly uses frequency conversion speed regulation to reduce the consumption of electricity. In terms of controlling the air volume, the traditional adjustment of the conventional blower and the induced draft fan is to adjust the opening of the damper flap, which does not have much significance for saving electricity. After the frequency conversion speed regulation technology is popularized, the frequency converter is used to change the frequency of the power supply, and the rotational speeds of the air blower and the induced draft fan are actively adjusted to adjust the air volume reasonably. The boiler is running at full capacity for most of the entire heating time, and this technology can save 40% of electricity. It is necessary to pay high attention to the energy saving of heating boilers, reduce energy waste, and continuously improve the social and economic benefits of heating, promote the development of energy-saving and environmental protection industries, and enable energy-saving services to achieve sustainable development goals.
