I. installation of fuel economizer
The viscosity of the hydrocarbon disposed by the fuel oil economizer decreases, which makes the fuel oil greatly advance in atomization and refinement in the past combustion. When the fuel oil is injected into the combustion chamber under the condition of low oxygen, it can obtain abundant combustion. Therefore, the air volume of the combustion equipment can be reduced by 15% to 20%, avoiding the heat taken away from the flue, and the flue temperature can be reduced by 5 ℃ to 10 ℃. After the fuel oil of the combustion equipment is disposed by the energy saver, it can save 4.87% to 6.10% of the fuel oil because the combustion is in accordance with the advance, and it is obvious that the flame is bright and striking, the black smoke is lost, and the furnace is clear and transparent. Thoroughly remove the coking phenomenon of the burning oil nozzle and prevent re coking. To eliminate the residue on the furnace wall due to the lack of abundant fuel combustion, and to achieve the environmental protection and energy saving consequences. It greatly reduces the air pollution caused by the exhaust gas from combustion equipment. The harmful components such as carbon monoxide (CO), nitrogen oxide (NOx), hydrocarbon (HC) in the exhaust gas are greatly reduced, and the emission of harmful exhaust gas is more than 50%. At the same time, the dust content in the waste gas can be lowered by 30% - 40%. Installation position: installed between the oil pump and combustion chamber or nozzle, and the ambient temperature should not exceed 360 ℃.
Two sets of condensing gas boiler economizer
The condensing type gas boiler economizer can be installed in the existing boiler flue to recover the energy in the high temperature flue gas, reduce the fuel cost, and have the most obvious economic benefits. At the same time, the condensation of water vapor absorbs the nitrogen oxide, sulfur dioxide and other pollutants in the flue gas, and the emission of low hanging pollutants has important environmental protection purposes
III. adopt condensation type waste heat recovery boiler technology
The boiler thermal compliance is calculated based on the low calorific value of fuel, without considering the heat loss of latent heat of vaporization in the high calorific value of fuel. The traditional boiler heat compliance can only reach 87% - 91%. While the condensing type waste heat recovery boiler, which lowers the exhaust gas temperature to 50-70 ℃, abundantly recovers the sensible heat in the flue gas and the latent heat of water vapor condensation, and improves the heat compliance; the condensate can also be recycled.
IV. heat pipe waste heat recovery technology adopted at the tail of boiler
Waste heat is the energy which is not used in the energy utilization equipment under the condition of economic and technological conditions, that is, the energy which is redundant and destroyed. It includes waste heat of high-temperature waste gas, cooling medium, waste water, high-temperature products and slag, chemical reaction, combustible waste gas, waste and high-pressure fluid. According to the investigation, the total waste heat resources of various industries account for about 17% - 67% of the total fuel consumption, and the recyclable waste heat resources account for about 60% of the total waste heat resources. Superconducting heat pipe is the main heat conducting element of the heat pipe waste heat recovery device, which is essentially different from the ordinary heat exchanger. The heat exchange compliance of the heat pipe waste heat recovery device can reach more than 98%, which can not be reached by any ordinary heat exchanger. Heat pipe waste heat recovery device is small, only 1 / 3 of the ordinary heat exchanger. The waste heat recovery device, which is composed of several heat pipes, is installed at the flue gas port of the boiler to absorb the heat in the flue gas and conduct it to the other end at high speed, so as to reduce the temperature of the exhaust gas to close to the dew point and reduce the loss of heat emission. After heating, the clean air can be used to dry materials or replenish them to the boiler for circulation. The heat compliance of the forward boiler and the home-made kiln reduces the cost of fuel and reaches the target of energy saving.
In the decision-making and manufacturing of domestic oil, gas and coal-fired boilers, in order to prevent the corrosion and ash blocking of the heating surface at the end of the boiler, the exhaust gas temperature in the standard state is generally not less than 180 ℃, and the maximum temperature is 250 ℃. The high-temperature exhaust gas not only causes a lot of heat energy waste, but also pollutes the environment. The heat recovery device of heat pipe can recover the heat of flue gas. The recovered heat certificate requires heating water to be used as boiler make-up water and livelihood water, or heating air to be used as boiler combustion supporting air or dry materials. Save fuel costs, lower manufacturing costs, reduce exhaust emissions, energy conservation and environmental protection. Revolutionary investment will be recovered in 3-10 months, with distinct economic benefits.
V. scale prevention and removal technology
Historically, the boiler scale remover, electronic scale preventer and softened water treatment equipment are used to optimize the water vapor circulation system. The softened water equipment may remove the scaling ions such as calcium and magnesium in the water, soften the water quality, reasonably control the blowdown rate of the boiler, so as to reduce the scale and advance the boiler heat compliance.
Vi. adopting fuel growth agent technology
In the fuel, the growth agent reaches the optimized fuel, reaches the low smoke scale, and advances the heat compliance index
Adopt new fuel
Adopt new environmental protection fuel oil to reach the target of low fuel cost.
VIII. Adopt oxygen enriched combustion technology
The oxygen content in the air is less than or equal to 21%. The combustion of domestic boilers is also carried out under such air. The reality shows that when the amount of oxygen in the gas burned by the boiler reaches more than 25%, the energy saving is as high as 20%; when the boiler starts up, the heating time is compressed by 1 / 2-2 / 3. And oxygen enrichment is to use the physical method to hold a web page of oxygen in the air, so that the oxygen enrichment content in the gas behind the web page is
