how to calculate efficiency of fire tube boiler

As to brick factories, they usually need steam and hot air in brick curing, drying process. An manager working in a brick factory, contacted with our consumer service online, he wanted to get the price of 10 ton coal fired chain grate how to calculate efficiency of fire tube boiler. As he said, the old one in brick factory served for 8 years, and lower efficiency and higher running costs now. Their factory decided to replace it and buy a new one finally. Coal fuel price is cheaper in local, easy to coal resource; thus they still want to use coal fuel as its energy. Our sales contacted with this factory and quote his the price of SZL series coal fired chain grate boiler, capacity 10 ton, pressure 1.25 MPa.

Hot water how to calculate efficiency of fire tube boiler heating industry is our essential equipment, gas hot water boiler water provided by the party fast flotilla, high thermal efficiency direct savings on fuel costs of inputs for our company, the intelligence facilities let the boiler run more convenient and effective to reduce the labor intensity of fireman people. --customer feedback

Henan gas how to calculate efficiency of fire tube boiler by techniques which optimize the effect of reduction of Henan gas boiler, i.e. the part of each combustion system design, heat exchanger components and control system can improve the boiler efficiency optimization techniques combined together, will be the maximum It may improve the thermal efficiency of the boiler, so as to achieve energy saving. 1. Using burner head premix metal fibers. First, natural gas and air through the venturi tube to achieve optimum mixing, the mixed gas is combusted in the combustion surface of the first woven fibers made of special alloy, burning more fully, more thorough, flame generation is extremely short, so the required combustion small room space, so a premix burner Henan gas boiler more compact. Secondly, when the premix type burner flame color is blue, the flame temperature of about 1000-1100 degrees, ordinary blower burner flame temperature greater than 1300 degrees, and the oxygen and nitrogen in the air from the start of the reaction is about 1200 deg.] C, A vigorous enhanced from 1500 ℃. Therefore, NOx emissions is much lower than condensing furnace blast other common boiler burner. Further noise premix burner produces approximately 40-72dBA, the blower noise generated by the burner is high 80-100dBA. A flexible metal fibers also avoid the generation of thermal stress of combustion head, extending the service life and maintenance intervals burner head. 2. Henan new gas-fired boiler using heat transfer enhancement of heat transfer tubes. In order to reduce exhaust gas temperature, the condensing effect is achieved, increasing the heat transfer area of ​​the heat exchanger must element, it should not be construed to simply increase the volume of the device to increase the heat transfer area. But should be reasonably increase the heat transfer area per unit area of ​​the device, and high thermal conductivity, and is corrosion resistant heat transfer tubes. 3. flood capacity design makes operation more sustainable, start and stop times smaller. Significantly reduced consumption and emissions. 4. Application of PVC exhaust pipe. Since conventional boiler flue gas temperature above 150 degrees, the chimney must be made of steel, but also the use of prefabricated chimney insulation layer stainless steel in some cases, the cost per square meter of the chimney 1600-1800 dollars, the cost is very expensive. Henan gas boiler due to lower exhaust gas temperature, standard PVC pipe may be used as exhaust pipe, the boiler is greatly reduced additional installation costs. 5. Henan gas boiler provided with the water receiving tray collected condensate, and the condensate and treatment before discharge. During condensation of gases and fly ash and soot fraction of the flue gas is dissolved in water, reducing the harmful substances discharged into the atmosphere. 6. The controller comes selection ratio control system and having a sound and timing of the operation mode. Fast and accurate continuous tracking load changes, to achieve good time-heating function.

• Boiler has a smaller foot print (up to 20 to 30% less building volume compared to a hot cyclone-based CFB how to calculate efficiency of fire tube boiler)

• Boiler design is especially suitable for retrofitting of older PC-fired boilers within the existing support steel.
