tube specification for medium pressure fire tube boilers

9. Produce according to the national standard, all pressurized components apply fine quality steel.

10. Every boiler must be subject to strict inspection and testing before delivery, including hydraulic test and X-ray inspection.

Pushing new fast tube specification for medium pressure fire tube boilers - a low nitrogen vacuum boiler "APH the T7" heavy starting at the show, numerous suction eye. "Thalia T7" launch, breaking the old burners + furnace construction mode, rational arrangement of low nitrogen burners, coupled with the furnace scientific, greatly enhance the operational efficiency of the boiler, the real "coupled," "burning "Tiancheng.

Henan gas tube specification for medium pressure fire tube boilers 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.

Heating tube specification for medium pressure fire tube boilers water wall installation What is the connection between the process and operation? Heating boiler water wall installation What is the connection between the process and operation? Since the water wall is located inside the furnace, fully understand the structure, and can know combustion furnace. At run time by measuring the wall temperature, the temperature of the header can be known indirectly working fluid parameters during inspection, we can find anomalies caused by internal squib early. By comparison of the dilation parameter, since early detection of coal boiler reasons, resulting in combustion of coke and the like is not generated properly. For operations personnel understand the structure helps to analyze the operating status of the boiler.
