1 Adding fuel; The hydrocarbon structure treated by the fuel energy saver changes the molecular structure, the number of small molecules increases, the distance between molecules increases, and the viscosity of the fuel decreases. As a result, the fuel oil is atomized and refined before burning. Increased, sprayed into the combustion chamber under full oxygen conditions to fully burn, so the combustion equipment can reduce the air volume by 15% to 20%, avoid the heat carried away in the flue, the flue temperature drops 5 ° C to 10 ° C. After the fuel of the combustion equipment is treated by the economizer, the fuel efficiency is increased, so that the fuel can be saved by 4.87% to 6.10%, and the flame is bright and dazzling, the black smoke disappears, and the furnace is clear and transparent. Thoroughly remove the coking phenomenon of the combustion nozzle and prevent re-coking. It eliminates the phenomenon that the fuel wall is not fully burned and the wall is stagnant, achieving environmental protection and energy saving effects. It greatly reduces the pollution of the exhaust gas emitted by the combustion equipment to the air. The harmful components such as carbon monoxide (CO), nitrogen oxides (NOx) and hydrocarbons (HC) in the exhaust gas are greatly reduced, and the 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 position: Installed between the oil pump and the combustion chamber or nozzle, the ambient temperature should not exceed 360 °C.
2 Install a condensing gas boiler energy saver;
The gas boiler exhaust contains up to 18% of water vapor, which contains a large amount of latent heat that is not utilized, has a high exhaust gas temperature, and has a large sensible heat loss. After the natural gas is burned, pollutants such as nitrogen oxides and a small amount of sulfur dioxide are still emitted. Reducing fuel consumption is the best way to reduce costs. Condensing gas boiler economizers can be installed directly in existing boiler flue, recovering energy from high-temperature flue gas, reducing fuel consumption, and economic benefits are obvious, while condensation of water vapor is absorbed. Nitrogen oxides, sulfur dioxide and other pollutants in the flue gas reduce pollutant emissions and have important environmental protection significance.
3 using condensing waste heat recovery boiler technology;
In the conventional boiler, the exhaust gas temperature is generally 160 to 250 ° C, and the water vapor in the flue gas is still in a superheated state, and it is impossible to condense into liquid water to release the latent heat of vaporization. It is well known that the boiler thermal efficiency is calculated based on the low calorific value of the fuel, and the heat loss of the latent heat of vaporization in the high calorific value of the fuel is not considered. Therefore, the thermal efficiency of traditional boilers can only reach 87% to 91%. The condensing waste heat recovery boiler reduces the exhaust gas temperature to 50-70 ° C, fully recovers the sensible heat of the flue gas and the condensation latent heat of the water vapor, and improves the thermal efficiency; the condensed water can also be recycled.
4 The heat recovery technology of heat pipe is adopted at the tail of the boiler;
Waste heat is the energy that is not used in energy utilization equipment under certain economic and technical conditions, that is, redundant and abandoned energy. It includes seven parts of high temperature exhaust gas waste heat, cooling medium waste heat, waste steam waste heat, high temperature product and slag waste heat, chemical reaction waste heat, combustible waste gas waste and waste heat and high pressure fluid residual pressure. According to the survey, the total waste heat resources of various industries account for about 17% to 67% of the total fuel consumption, and the waste heat resources that can be recycled are about 60% of the total waste heat resources. The superconducting heat pipe is the main heat conducting component of the heat pipe waste heat recovery device, and is substantially different from the ordinary heat exchanger. The heat exchange efficiency of the heat pipe waste heat recovery device can reach more than 98%, which is unachievable by any common heat exchanger. The heat pipe waste heat recovery device is small in size, only 1/3 of the ordinary heat exchanger. The working principle is as shown in the figure: the left side is the flue gas passage, and the right side is the clean air (water or other medium) passage, and the partitions in the middle are separated from each other. The high-temperature flue gas is discharged from the left channel. When the exhaust gas temperature is >30 °C, the heat pipe is automatically activated to conduct heat to the right side. At this time, the heat pipe is heated to the left, and the high-temperature flue gas flows through the heat pipe. The temperature drops and the heat is absorbed by the heat pipe and conducted to the right. At normal temperature, the clean air (water or other medium) flows under the action of the blower and flows in the opposite direction of the right channel to flush the heat pipe. At this time, the right side of the heat pipe releases heat, and the clean air (water or other medium) is heated, and the temperature rises after the air flows through the heat pipe. A waste heat recovery device consisting of several heat pipes is installed in the boiler mouth to absorb heat from the flue gas and conduct it at high speed to the other end, so that the exhaust gas temperature is reduced to near the dew point and the heat loss is reduced. The heated clean air can be used to dry the material or be replenished to the boiler for recycling. Improve the thermal efficiency of boilers and industrial furnaces, reduce fuel consumption, and achieve energy saving.
In the design and manufacture of industrial fuel, gas and coal-fired boilers, in order to prevent corrosion and clogging of the heating surface of the boiler tail, the standard state exhaust temperature is generally not lower than 180 ° C, up to 250 ° C, high temperature flue gas emissions not only cause a lot of heat energy Waste, but also pollute the environment. The heat pipe waste heat recovery device can recover the heat of the flue gas, and the recovered heat is used as boiler hydration and domestic water according to needs, or heated air is used as a boiler combustion air or dry material. Save fuel costs, reduce production costs, reduce emissions, and save energy and environmental protection. The transformation investment is 3-10 months, and the economic benefits are remarkable.
5 Adopt anti-scaling and descaling technology;
By adopting boiler descaling agent and electronic anti-scaling device, the water vapor circulation system is optimized, and the sewage discharge rate of the boiler is reasonably controlled, thereby reducing scale and improving boiler thermal efficiency.
6 using fuel additive technology;
Adding additives to the fuel to optimize the fuel, achieving the purpose of reducing the scale and improving the heat efficiency;
7 using new fuels;
The use of new environmentally friendly fuel oils achieves the goal of reducing fuel costs.
8 using oxyfuel combustion technology;
The oxygen content in the air is ≤ 21%. The combustion of industrial boilers is also carried out under such air. Practice shows that when the amount of gas oxygen in the boiler is more than 25%, the energy saving is as high as 20%; the boiler start-up time is shortened by 1/2-2/3. Oxygen enrichment is the application of physical methods to collect oxygen in the air so that the oxygen content in the collected gas is 25%-30%. Oxygen-enriched combustion is a new energy-saving and environmentally friendly technology. In the past ten years, with the continuous improvement of environmental protection requirements and the need to save energy, oxyfuel combustion has flourished as an emerging combustion technology in all countries of the world. Now some western developed countries require that all new industrial furnaces and industrial boilers should not be added. With ordinary air to assist combustion, it is necessary to use oxygen-enriched air to assist combustion.
9 using swirling combustion boiler technology;
As we all know, there are two major drawbacks in traditional boilers. One is that smoke and smoke appear when burning, and it becomes an important source of pollution. Second, the combustion of cinder is insufficient and energy waste is extremely serious. The new technology of pure smokeless and energy-saving cyclone combustion boilers has an absolute advantage compared with traditional industrial boilers. It saves 30% to 35% of coal compared to hand-fired boilers and 25% more than coal-fired chain boilers. Because the pure smokeless energy-saving technology uses PID frequency conversion and ABM power-saving system, it can save more than 90% of the volatile matter and save more than 90% of the combustion and utilization of the traditional boiler. The burnout rate of the volatile of the traditional boiler is only 78%. Around 22% of the soot is discharged into the atmosphere. The pure smokeless and energy-saving swirling combustion technology makes the ash burnout rate reach 97%, while the traditional boiler cinder burnout rate is only about 80%. It is for these reasons. The pure smokeless and energy-saving combustion technology can increase the furnace temperature from 1200 °C to 1500 °C, improve the combustion efficiency, save fuel and meet the needs of customers.
