papermaking biomass hot water boiler price
Fangkuai Company has a fully-automatic PLC intelligent control system designed and developed by itself with complete intellectual property rights. It adopts a combination of mechatronic control equipment and a programmable logic controller (PLC). Take the advanced programmable logic controller (PLC) as the "central processing unit" of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the boiler, and the operation is simpler and more intuitive.
In a pressurized fluidized bed boiler, the entire fluidized bed combustor is encased inside a large pressure vessel. Burning solid fuels like coal and biomass in a pressurized fluidized bed boiler produces a high-pressure stream of combustion gases. After the combustion gases pass through a hot gas cleanup system, they are fed into a gas turbine to make electricity, and the heat in the hot exhaust gas stream can be recovered to boil water for a steam turbine. Therefore, a pressurized fluidized bed boiler in ZG company has high efficiency and good performance. Each year, ZG invested a lot of money on pressurized fluidized bed combustion technology. Higher techonology and better efficiency is ZG Boiler pursue.
There are build on the control of emissions of nitrogen oxides boiler in order to achieve NOx emissions from combustion boilers of less than 30mg / m3, reached the world advanced level. Austrian far low nitrogen fuel gas boiler Staged Combustion Process of the invention into three regions in the furnace combustion techniques, primary combustion zone into the small portion of the fuel, the fuel required for the combustion air into the furnace in stages, the air volume of 80% left and right into the main combustion zone, the primary combustion zone of the upper (downstream of the flame) of the fuel injected into the secondary combustion and the formation of Carrying out a reducing atmosphere in the third zone into the combustion air required Further, complete burnout process. To create a discharge for the control of nitrogen oxides boiler fuel and air in order to achieve staged combustion gas boilers achieve emission limits is very basic configuration of environmental protection facilities, comprising an electrostatic precipitator or bag filter, gas boiler efficient desulfurization apparatus, a selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) and the like denitration apparatus. All aspects of air pollution sources to install automatic monitoring facilities, steam boilers and networking with the environmental protection department, install a distributed control system (DCS system), real-time monitoring of gas boiler pollutant emissions. All-premixed combustion technology implementation of a number of Austrian far improved combustion technology after years of build have on the control of emissions of nitrogen oxides boiler fuel and air in order to achieve staged combustion. This technique can be gas boiler NOx emissions chain by 70% -60%. At present, to solve pollution problems of small and medium industrial gas boilers have four energy saving way. First, clean fuels covered by the remaining gas boilers, boiler premix combustion technology implementation of a number of improved combustion technology after years of Austrian far as natural gas boilers, biomass boilers and so on; Second, the rising water boiler technology.
The solid fuel fired and biomass fired boilers are mainly used in hotel, hospital, university, central heating, refineries, utilities, petrochemical, chemical, paper and pulp, steel and iron, food processing, power station, and other major processing industries. Solid fuel boiler is chain grate type boiler burning coal, biomass or mix-firing both. It adopts membrane water wall, with economizer in the rear of boiler. High combustion efficiency, energy saving and low emission. Three-pass tube design incorporating a wet back turnaround that eliminates the need for rear door refractory. Larger steam disengagement area providing high quality steam, larger steam storage capability for quicker response to sudden steam demand. Equipped with PLC-based control system to realize automatic operating in start-up, standby and shutdown control Designed, constructed and stamped in accordance with the requirements of the American Society of Mechanical Engineers.
