Waste heat is not wasted
1. Install fuel economizer
The hydrocarbons processed by the fuel economizer reduce the viscosity of the fuel, which greatly increases the degree of atomization and refinement of the fuel oil before combustion. It is sprayed into the combustion chamber to be fully combusted under low oxygen conditions, so the air volume of the combustion equipment It can be reduced by 15% to 20%, to avoid the heat taken away in the flue, and the temperature of the flue drops by 5 ℃ to 10 ℃. After the fuel of the combustion equipment is processed by the energy-saving device, due to the improved combustion efficiency, it can save 4.87% to 6.10% of the fuel, and it is obvious that the flame is bright and dazzling, the black smoke disappears, and the furnace is clear and transparent. Completely remove the coking phenomenon of the combustion oil nozzle and prevent re-coking. The phenomenon of residue accumulation on the furnace wall due to insufficient combustion of fuel is eliminated to achieve the effect of environmental protection and energy saving. Greatly reduce the air pollution of the exhaust gas emitted by the combustion equipment. The harmful components such as carbon monoxide (CO), nitrogen oxide (NOx), hydrocarbon (HC) in the exhaust gas are greatly reduced, and the discharge of harmful exhaust gas is reduced by more than 50%. At the same time, the dust content in the exhaust gas can be reduced by 30% -40%. Installation location: installed between the oil pump and the combustion chamber or nozzle, the ambient temperature should not exceed 360 ℃.
Second, install condensing gas boiler energy-saving device
The condensing gas boiler energy-saving device can be directly installed in the existing boiler flue, recovering the energy in the high-temperature flue gas, reducing fuel consumption, and the economic benefit is very obvious. At the same time, the condensation of water vapor absorbs the pollution of nitrogen oxides and sulfur dioxide in the flue gas Reduce the emission of pollutants, which has important environmental protection significance.
3. Adopt condensing waste heat recovery boiler technology
Boiler thermal efficiency is calculated from the low calorific value of fuel, without considering the heat loss of the latent heat of vaporization in the high calorific value of fuel. Therefore, the thermal efficiency of traditional boilers can generally only reach 87% to 91%. Condensing waste heat recovery boilers reduce the exhaust gas temperature to 50 to 70 ° C, fully recover the sensible heat in the flue gas and the latent heat of condensation of water vapor, and improve Heat efficiency; condensate can also be recycled.
Fourth, the tail of the boiler adopts heat pipe waste heat recovery technology
Waste heat is energy that is not used in energy utilization equipment under certain economic and technological conditions, that is, excess and waste energy. It includes seven kinds of high-temperature waste heat, cooling medium waste heat, waste steam waste heat, high-temperature products and slag waste heat, chemical reaction waste heat, combustible waste gas waste liquid and waste waste heat, and high-pressure fluid waste pressure. According to the survey, the total waste heat resources of various industries account for about 17% -67% of its total fuel consumption, and the recyclable waste heat resources are about 60% of the total waste heat resources. Superconducting heat pipes are the main heat conduction elements of heat pipe waste heat recovery devices It is essentially different from ordinary heat exchangers. The heat exchange efficiency of the heat pipe waste heat recovery device can reach more than 98%, which cannot be achieved by any ordinary heat exchanger. The heat pipe waste heat recovery device is small in size, only 1/3 of the ordinary heat exchanger. A waste heat recovery device composed of several heat pipes is installed in the smoke port of the boiler to absorb the heat in the flue gas and conduct it to the other end at a high speed, so that the temperature of the exhaust gas is reduced to close to the dew point and reduce the heat emission loss. The clean air after heating can be used to dry materials or replenish the boiler for recycling. Improve the thermal efficiency of boilers and industrial kilns, reduce fuel consumption, and achieve the purpose of energy saving.
In the design and manufacture of industrial fuel, gas, and coal-fired boilers, in order to prevent corrosion and ash plugging on the heating surface of the boiler tail, the standard flue gas temperature is generally not less than 180 ℃, up to 250 ℃, high temperature flue gas emissions not only cause a lot of heat Waste, but also pollute the environment. The heat pipe waste heat recovery device can recover the flue gas heat, and the recovered heat can be used to heat the water as boiler make-up water and domestic water as needed, or the heated air can be used as boiler combustion air or dry materials. Save fuel costs, reduce production costs, reduce exhaust emissions, energy saving and environmental protection. The investment of transformation is recovered within 3-10 months, and the economic benefit is remarkable.
5. Adopting anti-scaling and descaling technology
By adopting boiler descaling agent, electronic anti-scaler and softened water treatment equipment, the water vapor circulation system is optimized. The softened water equipment can remove calcium and magnesium and other scale ions in the water, so that the water quality is softened, and the boiler blowdown rate is reasonably controlled, thereby reducing scale To improve the thermal efficiency of the boiler.
