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.
About boiler, daily attention to ten o'clock analysis of its original meaning, it means the pot is heated in a water container on the fire place burning stove refers to fuel the boiler including the two most from the pot and stove included. Today, we say that the boiler is the use of fuel or other energy hot water heating can become mechanical equipment of hot water or steam. Generating hot water or steam boiler may provide heat directly to the required industrial production and the people's living, the steam power plant can also be converted into mechanical energy by the generator can convert the mechanical energy into electrical energy. Because the frequency of use of the boiler is high, so it's for routine repairs and maintenance is also very important, here are ten aspects regarding boiler need attention, we divided into two parts to illustrate: First, note the boiler: (1) boiler factory, should be accompanied by quality certification, safety instructions and other supporting information. (2) boiler installation, maintenance and renovation should be obtained qualifications in this area for the job, not blindly, to avoid problems. (3) boiler to be registered before the registration can be used, and to be performed by professional job. (4) the operator while operating the boiler, and eight systems should abide by the rules and six records. (5) boiler and its safety accessories to be tested on a regular basis, no test can not be used. Second, boiler routine maintenance: (1) Check the boiler pressure gauge, water gauge, safety valve, sewage plant, the steam supply valve and the valve and verify its compliance with the performance requirements. (2) Check the automatic control device system meets the requirements. (3) Check the boiler feedwater system meets the requirements. (4) on the blower, induced draft fan, damper, etc., to see if intact, is working. (5) boiler should be regularly checked once a problem is found to be in time, so as not to affect the normal operation.
The biomass fuel in Power plant is consumed using a direct-fired process similar to fossil fuel-fired power generating plants, but with lower air emissions. The fuel burns and heats water in a biomass power plant boiler that produces high-pressure steam, which is then piped to a steam turbine where it flows over a series of aerodynamic blades, causing the turbine to rotate. The turbine is connected to an electrical generator that produces the electricity.
