Condensing boiler condensing heat exchanger selection problem: all parts of the condensing boiler is in contact with the condensate, such as a condensing heat exchanger, flue gas duct and the induced draft fan must be suitable corrosion resistant material. I copper, aluminum two materials were compared, the aluminum alloy material found suitable for this research project more. ① copper and aluminum fin efficiency comparison: Ek reinforcement measure the relative percentages of the respective physical quantity of copper instead of aluminum fins fin (fin efficiency, heat transfer, heat transfer coefficient, etc.) change with the fin efficiency heat conducting fins improve the coefficient increases. However, the specific amplitude increases, the fin is limited by Movies Ⅱ material itself, the structure and the air-side heat transfer coefficient. In this study, we fin thickness of 0.02-0.18mm, and the fin height of 5-30mm air side heat transfer coefficient of 60 ~ 160WW / (m2 • K) of copper and aluminum fins of fin fins fin efficiency were analyzed and compared. After comparison, the copper fin fin efficiency is higher than about 0.938% aluminum fin ~ 29.86%. Different structures and conditions of copper, aluminum fins ② overall heat transfer coefficient on the refrigerant side heat transfer area per unit comparison: Typically, the total surface area of the side fins An overall heat transfer coefficient of the finned tube can be calculated as a reference :
Before and after the smoke cover the activities of 1.5 t steam boilers equipped with fuel (gas) boiler is a horizontal internal combustion quick three-pass fire tube boiler. Furnace using offset wet back structure, with high temperature flue gas boiler steam boiler sequentially flushing the second and third return pipe tobacco, and then discharged into the atmosphere through the chimney of the smoke chamber. Activities before and after the boiler is equipped with smoke cover, the boiler easy maintenance. Good performance boiler configuration techniques industrial burners, combustion using automatic ratio adjustment, automatic adjustment of water supply, the program start and stop, automatic operation and other advanced technology, and having a low water level and low level alarm, high steam pressure, automatically flameout Protective function. The boiler has a compact structure, easy to operate, quickly installed, before and after the smoking activities cover less pollution, low noise, high efficiency. The boiler is ready to leave the factory. Burner, automatic control units, pumps, valves, meters, smoke and other air duct to take over, boilers, according to the drawings supporting the factory or the factory according to the contract. Two random technical documents provided by the factory technical documents list. four. Control System Description! Used half-ton automatic gas fuel steam boiler Buying used equipment for sale where to buy Condition new, buy used equipment to find Liangshan County Lighthouse chemicals are cheap, supply delivery to Liangshan County Lighthouse chemical equipment operators, will not let you re spend a money wasted. Thank you for calling Liangshan Wang Chongli now recovered and the number of well-known equipment manufacturers reached a long-term cooperation agreement, has become Tung Fu Long,? The gas-fired boiler using automatic good technical properties as the main burner combustion apparatus, the combustion process of the burner by a combustion process controller more advanced controls.
Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler products, in March 2017 signed a six-ton steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.
How condensing gas furnace functions: gas condensation in the furnace during operation, as with a conventional boiler, water is heated by the heat of combustion. Combustion flue gas is typically discharged through the flue. Thus, the heat in the flue gas will be exhausted to the outside. However, the flue gas condensation technique may be utilized. Since the flue gas is composed by a large number of high-temperature steam, condensation techniques may utilize flue gas heat, and then the heat acquired input heating circuit.
