Small electric steam generator What are the benefits, features? First, electric and gas, fuel oil to generate steam compare the advantages and disadvantages: advantages and disadvantages of gas: Advantages: coal is the most economical energy per kilogram of coal can produce more than 5,000 calories, can produce around 60,000 kg of steam (theoretical value). Both economical than electric, fuel oil and natural gas. Disadvantages: 1, low efficiency, although theoretically per kilogram of coal can produce more than 5,000 calories, but due to the limitations of the gas 6ton diesel generator and the Boilermakers by human factors, the real heat of the steam is converted to produce far less than the theoretical value, the heat efficiency of around 60%. 2, can not do automatic control, if the device is not continuous steady steam steam that instant steam consumption fluctuations, the steam produced by the boiler with the steam in the bottom of the valley steam equipment can only let go waste. 3, need specialized operators, high labor costs. 4, do not meet the requirements of modern environmental protection, banning small gas boiler is the trend. The advantages and disadvantages of fuel: fuel meets the requirements of environmental protection, the state has not been expressly provided, however, based on current oil prices, its economy has ceased to exist. Per liter of oil can produce more than 18,000 calories, about 60% utilization, we can produce about 10 kg of steam. Which produce one ton of steam costs around 800 dollars (at current prices). The advantages and disadvantages of heating: Cons: Because electricity is converted from the other sources of energy, so the relatively high price point, once electricity can produce about 1.5 kg of steam. Calculated to produce 1 ton of steam costs about 400 yuan or so based on the current average domestic electricity bill. More expensive than gas. Advantages: 1, high efficiency, above 98% heat utilization. 2, it is possible to achieve automatic control device can automatically adjust the operation of the equipment in accordance with the amount of steam vapor apparatus, according to how much power consumption is the amount of steam may be. There is no waste. Particularly suitable for the case of steam is not constant. For example: a user selection of 0.5 t / h of electric steam generator, power is 360KW equipment, operation at full load, the theoretical power consumption of 360 degrees / hour, but if the user one hour using 200 kg of steam only, then only the power 140 degrees. In many industries such as: medical and pharmaceutical industry sterilization, washing and drying equipment, chemical equipment, etc., the amount of steam is intermittent, this situation if you use gas-fired boilers, there will be large
Opening the water supply valve motor, regenerative electric closing valve, a pressure pump to start the cycle frequency control constant voltage supply, electric 6ton diesel generator starts after about 30 seconds, in such a manner direct supply water to the user. At the end of the water supply, stop circulating pressure pump, electric boiler stops after 60 seconds. When the water reaches the time period, the electric power boiler feed water valve is open, regenerative electric valve is closed, the electric boiler is not working, the circulation pump frequency control water supply pressure. Electric power supply period of boiler feed water valve has been closed, not to pay it to avoid the cold water supply to the user. If the heat storage tank and the temperature is below the set temperature in the regenerator period of 5 ° C, pressure circulation pump into operation again, electric boiler start working after 30 seconds.
Environmental characteristics and working principle of the 6ton diesel generator burner in recent years, with the emergence of environmental progress boiler burner and integrated development of the regenerator, as well as fast-acting valves and electronic control system of the program longer life a significant savings the new regenerative energy and environmental protection boiler combustion engine has been started in some foreign high-temperature industrial kiln. First, the features of the new green regenerative burner boiler 1, 90% of the heat recovered from the flue gas can be reused, thus saving 50 to 60% of the fuel. 2, thermal properties quite stable. Not affected by the quality of the furnace flue. 3, may use natural gas or some other fuel gas, light oil or heavy oil combustion. 4, compact structure, easy installation, a short payback period. 5, to improve the working conditions of the furnace, greatly reducing the maintenance of the furnace. 6, can be formed in the furnace - a good temperature distribution, thereby improving product quality and production capacity of the furnace. In the United States, Britain, France, Japan, West Germany and other industrialized countries, at least 500 such devices have been used on industrial furnaces. Second, the composition and working principle of environmental protection regenerative burner of this new heat recovery boiler burner principles of environmental protection boiler flue gas heat recovery is achieved by a small regenerator with the self. 2 is equipped with a set of gas burners in a heating furnace, each burner in the lower portion, a small accumulator is mounted a ball filled with AL2O3, an air inlet connected to the upper space of the regenerator and burner , in addition to the bottom of the heat accumulator is connected via a combustion air pipe and an outer valve, the valve is further connected via another exhaust pipe. In operation, assume that the furnace temperature reached 900 ℃, air enters the front of the burner used (valve opening) from the bottom of the regenerator, increases to a burner fed by 8O0 ℃ filler layer inside the regenerator temperature, gas the fuel discharged from the high-speed burner rear axially into the furnace with the combustion air is mixed with the high temperature, environmental protection boiler burners installed to the furnace wall at an angle, so that a high speed gas can be injected into the combustion furnace flue gas and forming vigorous stirring to achieve uniform temperature in the furnace. Since the combustion process of the furnace is in the form of a closed state, the fuel gas into the combustion furnace exhaust gas should be balanced, the flue gas discharge outlet from another burner reverse flow from the air inlet through the regenerator packing layers of It flows from top to bottom, AL2O3, and the ball is in direct contact with high temperature and flue gas heat exchanger, and a temperature gradient in the order of packing layers. Reaches the lower flue gas is cooled by heat exchange, and then (valve opening) from the exhaust port through the exhaust pipe discharge (when the air inlet valve at the bottom of the regenerator is in the closed state). In this way a few minutes until the continuous operation, the temperature rises AL2O3 balls, reaches the outlet exhaust gas temperature (e.g. 150 ~ C). In contrast, since the front of the regenerator into the combustion air is cooled to remove heat, the temperature of hot air sent to the burner is gradually lowered (e.g., to about 700 ℃). Time to dig through a temperature program control system, two burners arranged together exchange valves 6, can be formed so that a work order: starting with the lower portion of combustion air into the regenerator, after the heating temperature reaches the burner, while discharging fuel gas, mixed with air into the furnace combustion temperature, part of this time a flow of combustion gas is inversely behind by the burner, while the internal accumulator fill ball cooled heat while discharging. Since this switching operation is automated, and thus the whole combustion process is carried out continuously. With this new environmental Burner preheating temperature of the air just below the gas temperature 100 ~ 200 ℃, the flame temperature is generally higher than 2200 deg.] C, the flame temperature results in cleavage of the fuel molecules (polymerization) of action, resulting in brighter flame more conducive to heat the furnace.
