When the user uses the gas boiler, the parameters first need gaseous fuel, such as ingredients, proportions, calorific value, in order to select the type combustor. We are on the two hot air - liquefied natural gas and liquefied petroleum gas were analyzed and compared, which help you clear the air supply is good. 1, liquefied natural gas (referred to as LNG)
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 :
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.
Gas-fired boiler to install indoor plumbing rules you need to follow when you purchase over the gas boiler, then immediately faced with the installation part of the boiler, this step is also very important aspect. First of all we must be clear, most of the boiler pressure vessel with pressure belonging, safety must be the top priority position. Therefore, we must choose a good installation qualification, professional installation of boiler units. Mounted gas boiler comprising an outer main boiler room and boiler room in two parts. A boiler room mounted gas boiler-room installation comprising a main valve instrumentation gas boiler, boiler feed water, drainage channels, flues, steam pipes and the like connected to the installation. After gas boiler in place, the installation can proceed to the matters specific installation process is as follows: 1, gas boiler valve installed before installation of the valve shall be visually checked, one by one, and the strength and tightness test, passing the valve, the internal water net, and 2, pipe installation gas boiler pipeline installation according to demands on the pipes, fittings, flanges QA should technical oversight registered pressure pipes, fittings, flanges regular manufacturer, must have the appropriate material alone, certificate, certificate of no material single pipe, pipe fittings, flanges will be allowed to use. Welded boiler tubes gas should meet the technical requirements, as follows: natural gas boiler before welding operator must go through the relevant technical training, assessment qualified to obtain operating permits skills, before taking a post operation is prohibited without a license welding. Gas boiler welding operators six months of continuous off-site, should be re-technical training before the post back operation after passing the examination. Gas boiler welding operators should have performance welding apparatus used, are familiar with product design, and process documents standard boiler. Welding operator should do a good job managing the welding site, the tool should be able to operate properly, proper care should welders welding process instructions or welding process card welding, the welder near the weld should be marked with the code stamp low stress. Tube groove on the interface should comply with the provisions of the drawings, the groove should be polished clean 10mm range, when applied together clamp jig counterparts, leaving a good clearance fixed spot, quality check and correct counterpart, when the welding line. Arc can not be carried out on the tube at the weld when welding gas boiler, when the arc receiving arc fill port. Weld on the tube, it should be fully finished prior to the welding pressure test. Users may not secretly install gas boilers, pressure containers, particularly gas pressure small steam boiler small steam boiler direct from with a gas hot water boiler, pre-installation to the quality supervision departments for approval, and the need to complete the entire installation process in the quality supervision department supervision. Second, the external gas boiler room installation project according to the needs and circumstances of their own.
