6 ton oil gas condensing energy saving fire forced circulation boiler used in paper mill

Last year, a paper mill based in Australia contracted a 6 ton oil gas condensing boiler which model is WNS6-1.25-Y.Q. Our company is responsible for all production work of this 6 ton/hr gas condensing steam boiler. The product utilizes condensation technology to effectively reduce the exhaust gas temperature and improve boiler efficiency. Moreover, the boiler adopts a number of advanced technologies to reduce the emission of harmful substances such as SOx, NOx and COx, and is an efficient and environmentally friendly solution for industrial boilers.

Efficiency of the CFB Combustion Process

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties. According to theEPA's "Combined Heat and Power Partnership Biomass fired cogeneration plant CHP Catalog," the scrubbing action of the bed material on the fuel also enhances the combustion process by "stripping away the CO2 and solids residue (char) that normally forms around the fuel particles . . . allowing oxygen to reach the combustible material more readily and increase the rate and efficiency of the combustion process."

AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam energy saving fire forced circulation boiler fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.

You must know the energy saving fire forced circulation boiler energy problems (induced draft fan power consumption rate, steam consumption) draft fan causes problems 1.1 boiler flue dust and fouling, in particular air preheater fouling, resulting in increased resistance to smoke duct . 1.2 boiler flue, tail heating surface and dust leakage. 1.3 Leakage Rate large air preheater. 1.4 furnace excess air coefficient is too large. 1.5 unit load changes, run the adjustment is not timely, resulting in furnace pressure is too large. 1.6 unit load or low frequent starts and stops. 1.7 coal into the furnace worse, from the design value. 1.8 low efficiency filter. 1.9 draft fan blade badly worn, low operating efficiency. 1.10 fan outlet flue gas desulfurization big resistance. 1.11 soda boiler pipes for leaks. 2, 2.1 to 2.1.1 operational measures to solve the problem of the strict implementation of soot blowing system to prevent the heated area ash, blocking ash, flue gas system to reduce resistance. 2.1.2 holding the induced draft fan, the flue gas separator baffles and dampers in the fully open position. 2.1.3 The experiment showed combustion boiler, proper control of excess air in the furnace. 2.1.4 adjustment chamber negative pressure, air leakage reduction furnace and the flue. 2.2 routine maintenance and testing 2.2.1 induced draft fan performance test to determine the optimum operating point and efficient workspace. 2.2.2 boiler, air preheater, a flue, ESP and other system leakage inspection, process. 2.2.3 timely check processing chassis, shaft seal leakage. 2.3C / D repair, eliminating defects 2.3.1 down strict accordance with movement clearance adjusting fan. 2.3.2 induced draft fan blade defect action elimination hand vane opening adjustment. 2.3.3 Importers and induced draft fan baffle opening check. 2.3.4 duct tightness check process. 2.3.5 wave plate replacement air preheater, rinsed sector plate gap adjustment. 2.3.6 eliminate dust defects and improve collection efficiency. 2.3.7 clean flue gas desulfurization system, flue resistance is reduced. 2.3.8 eliminate soda boiler pipe leakage defects. 2.4A / B repair and transformation 2.4.1 Check and repair the fan blades, replace seriously damaged blades if necessary. 2.4.2 for energy saving fan efficiency below 75%. 2.4.3 The fan motor frequency transformation. 2.4.4 of the precipitator, if necessary, transform and improve collection efficiency.
