Gas furnace drive the actual speed for a given speed deviation how to do? Making equipment at normal temperature air through exhaust fumes recovery, heat transfer efficiency of the air reached 200 ~ 400 ℃, significant savings in fuel, increasing the effective calorific value gas furnace prices, energy-saving effect than similar products increased by 20%; in One is to increase the mixing ratio increased gas production efficiency, but also to make improvements to combustion skill. In the actual gas production, gas stoves, mostly semi-open production, gas furnace used for the fixed bed gasifier whole. Such gas system is operated under high pressure, there is no outside air intake may be, but also because of its high pressure, sealing equipment and piping systems also require high, the device should be weak or vulnerable at the direct impact of blasting blast The part of the installation burst valve. The requirements for gas furnace speed accuracy is relatively high, even if the load changes also require close to a given speed operation of the occasion, the drive can be used with a feedback function pg. Open-loop, the inverter output if a given frequency, the motor is running with load, the motor speed in the range of the rated slip (1% -5%) change. Exploration and research dedicated incinerator furnace gas: urban industrial waste and domestic wastes in landfills more desirable way, in addition to causing take up a lot of land resources, but also because the landfill on the ground causing secondary groundwater resources and soil pollution, gas furnace greater impact on our ecology. China's current approach to the treatment of municipal industrial or residential garbage, most of the establishment of large-scale waste disposal site in the suburbs, by way of essentially incineration and landfilling. Waste ferrous metals and non-ferrous classify pre-combustion and post-combustion is completed slag sorting recycling (waste within the mixed non-ferrous metals in the environment may be less than 1150 ℃ melt into a massive, easily cleared). Incineration of industrial furnaces simple addition produce large amounts of carbon dioxide and other exhaust gas stoves, have also increased the combustion system, gas furnace burning material all fossil fuels such as natural gas, fuel oil and coal, the fuel products are on Earth dwindling non-renewable energy materials. At present two-stage gas furnace, there are several problems to be solved: industrial waste and civilian Garbage: This is consistent with the principle of municipal waste incinerators as combustible garbage accounted for not less than 50% of the total; chunks of garbage should be After breaking through a diameter less than 250mm of lumps of small gas furnace into the combustion chamber. Saving gas furnace coal consumption: heating value of combustible waste much, generally can not be calculated before combustion, but the scene after combustion, slag vertical mill can be determined according to the requirements. Gasifier cold wall effect major technical indicators: Rotary overhaul limits illustrate solely from the perspective of gas, the higher the temperature of the furnace wall as possible, but the inner wall of the water jacket is the choice of material is generally 20G or 16MnR, which allows the use of temperature 450cC are less affected by the temperature of the furnace wall material permitted limit, the operating temperature controlled molten salt at 300 ℃ ~ 400 ℃, furnace wall temperature can be more than 400%, significantly increases the heat storage furnace, steam decomposition rate significantly increased, effectively solve the problem of cold wall effect. The new gas furnace gas furnace wall plate half-pipe coil using structures to d) 2810 / tapered jacket in 2610, for example, in the original Wall simplified outer jacket inner disk half pipe through high-temperature molten salt to reduce the temperature of the furnace wall. Fixed layer intermittent gas blowing stage method based on the air as gasification agent, air upwardly through the fuel layer, carbon is oxidized and release heat, providing heat for the gas phase, the main reaction is as follows: C + 01 = C02 + Q2c + 02 = 2co + Q2co + 02 = 2c02 + Q and the main stage of the reaction gas is water vapor as the gasifying agent gasification, water vapor and carbon gasification reaction of the main floor is as follows: C + 2H, 0 (steam) = CO, + 2H, QC + H20 (vapor) = CO + H2 a primary restore layer Q generated CO: reducing layer is reduced in order to co, blossom makes us more aware of the value of tube mill reaction is as follows: C02 + c = 2c0 a Q at lower temperatures, side reactions occur, reaction is as follows: C + 2H2 = CH4 + Qco + H20 (vapor) = C02 + H2 + Q as described above Fuhua gas furnace is gas reaction process is mainly carbon and steam, the steam is decomposed. The main reaction is an endothermic reaction, temperature increase can accelerate the reaction. The higher the temperature, the better the reduction reaction of steam and carbon dioxide, the more unfavorable side reaction of methane and carbon dioxide were produced, thereby obtaining a high vapor decomposition, and reduce coal consumption.
