Environmental characteristics and working principle of the boiler 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.
Gas-fired boiler or electric boiler which is good?To compare the two kinds of boilers better, we need to understand the advantages and disadvantages of the boilers. The advantages of electric boiler are: 1, high thermal efficiency: can meet the requirements of winter heating in all regions; 2, electric boiler is beneficial to environmental protection: no leakage, low noise, no pollution; 3, convenient use: automatic control, no special guard; Intelligent thermostat automatic control, flexible and convenient use, indoor temperature can be set by their own needs, start and close the machine can be controlled by the computer. The disadvantages of electric boilers are: 1. The operation cost is high, is gas-fired boiler 2 times, is gas-fired boiler 4 times. 2. The boiler must be supplied with three-phase electricity at 380 volts. If there is a power loss or power outage, there is no alternative. Seriously affect the normal production and operation of enterprise units. The advantages of gas-fired boiler are as follows: (1) the thermal efficiency is as high as 90%: it can meet the requirements of hot water heating in all regions; 2. Gas-fired boilers are conducive to the national strategy of energy conservation and emission reduction, collect agricultural and forestry wastes such as straws that are directly burned and cause pollution, and produce gas granular fuels through processing, which can bring benefits to farmers. Greatly reduce emissions of pollutants from exhaust gases. 3, convenient use: full automatic control, no special guard; flexible and convenient use, 4, gas fuel is similar to coal gasification combustion and suspension combustion state, flue gas stays in the high temperature furnace for a long time, through the use of the gas fuel is similar to the coal gasification combustion and suspension combustion state. Multiple air distribution, anaerobic, upper feed, lower fire, lower suction combustion, full combustion, high fuel utilization rate, no black smoke. 5, using the furnace dust removal device, with which the original concentration of boiler dust emission is low, can not use chimneys. 6, continuous fuel combustion, stable operating conditions, do not be affected by the addition of fuel or stabbing, can ensure output. 7, the fuel source is extensive, the cost is low. Not limited by the season, can be used throughout the year. The gas-fired boiler is half of the gas-fired boiler, 1/3 of the oil-fired boiler and 1/4 of the electric boiler. 9. Fangkuai gas-fired boiler In a modular design, each system uses one furnace body, two combustion heads or two furnace heads, one burner head 300000 truck in summer, and two burner heads 600000 truck when heating in autumn. When the coldest in winter, you can open four burning stoves 80-1.8 million truck, that is, the heating boiler only uses 300000 calories in summer, 600000 calories in autumn, 1.8 million calories in winter, one machine multi-use. In this way, customers do not need to invest in two sets of equipment systems, greatly reducing their first investment costs and operating costs. The disadvantages of gas-fired boilers are: 1. Need free space or The warehouse is used for storing gas particle fuel; 2. Blower induced fan and other accessories need 220 volts, affected by power outages, but diesel engine can be used to power boiler accessories. Keep the boiler running as usual! Summary: gas-fired boilers and electric boilers are environment-friendly boilers, automatic control, can adapt to various areas, the price of raw materials is stable; but the operating costs of electric boilers are too high to be affordable by ordinary enterprise units. Too much reliance on electricity, once there is a power outage, will seriously affect the normal production and operation of enterprises. Gas-fired boiler is different, in all clean energy boilers, its comprehensive operation The lowest cost. Although electric drive boiler accessories are needed in ordinary operation, the dependence on electricity is not great, and diesel generator can be used to operate power driven boiler fittings in the state of blackout. Because gas particles fuel ignition point, is not flammable, so even if the stack in the aisle side also does not matter. Overall: gas-fired boiler is better, can save a lot of operating costs for enterprises, economic, practical and environmental protection, and its small shortcomings easy to solve the impact of little.
