Heat Recovery Steam Generator In Ammonia Plants

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.

Tubular steam boiler gas boiler plant in Henan: Iannone fuel boiler heat recovery steam generator in ammonia plants exemption certificate for the use of the unique design of the internal structure of the series water volume is less than 50L, within the exemption permits boiler use a range of countries that use the certificate without going through the boiler . Furnace is equipped with a built-in separator, to solve the problem of steam with water, and more to ensure the quality of steam. Fuel steam generators advanced automatic control system for the automatic control of boiler operation, all operating states are available at a glance on the LCD screen. You can observe in the display to the burner working condition, biomass burning furnace gas state level Tubular steam boilers, boiler plants current temperature, feed pump running status, DZH type moving grate biomass steam boiler. Failure alarm status, allowing you to keep abreast of boiler operating conditions, use more confidence. Fool a control key, a single button press enter the automatic running, LSH vertical biomass steam boiler, all the safety devices are to work without special duty, the operator more secure, are to work Tubular gas steam boiler worry.

How steam boiler steam metering? Whether or not electrically heated heat recovery steam generator in ammonia plants is a steam boiler? Steam boiler steam metering, the corresponding meter is used to achieve the purpose, in general, may be used to remember the amount of steam flow meter, which can display the cumulative flow and the instantaneous flow, either in a liquid crystal display display, and water meters and can be the same counter. If it is the same for the steam boiler of multi-user, then, were installed in the branch line flow meter, to achieve their goals. Electrically heated steam generator, from a professional point of view, which is a water supply system, the automatic control system, furnace, heating systems and security systems to these, working principle thereof, by an automatic control means to ensure that during operation the controller normally liquid be opened and closed, and further, to ensure the normal operation of the steam generator. Therefore, from the definition and configuration point of view, it is not a steam boiler, these devices are two different devices.

Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam boiler for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.
