natural gas condensing hot water boiler boiler

Three tempering tube condensing hot water boiler boiler installation and commissioning of the structure outlined hot water boiler is fast loading of the internal combustion level. A second high temperature flue gas successively washed roots and refluxed for three breathing tube, the smoke chamber into the atmosphere through the chimney. Gas hot water boiler equipped with the world famous burner, combustion using automatic adjustment, automatically adjust the water supply, the program starts, automatic control and other functions. The boiler has a compact, safe, reliable, easy to operate, installation speed, low pollution, low noise, high efficiency. Widely used in enterprises, hotels, hospitals, office buildings, civil construction and other industrial steam, life, mining and other facilities. This installation requires fast speed boiler installation, installation is very simple, the boiler does not require special ground base, only enough to withstand the ground to power. 1. Install the water supply line requires the highest level reservoir, generally not critical, the high from the ground to the reservoir tank, underground tank of water should be kept clean. Pool water outlet. For wire entrance filter water supply line. 2, the straight cross-section is mounted, the return pipe return pipe to be 0.5 meters above the bend radius should be 4 to 5 times the diameter of the pipe, the pipe should be installed at the highest automatic steam valve to prevent the steam from the pipe loop. At the same time, the general requirements of the highest level possible reliable reserve pool. When the boiler water level is below the line, the water will flow into the boiler when the next time you start. Filter wire 3 should be installed at the outlet (i.e., the inlet pipe) of the pool. Installation requires a supply line Burner fuel hose has two interfaces, and for the oil return into the oil, as long as the boiler return oil chamber and the oil corresponding feed pipe. Dedicated hydraulic system from the boiler tank to the burner pump port, an operation instruction for the burner 4 is provided. Chimney straight chimney installation requirements. The length of the chimney should not be too long, the stack height should be less than 5 meters. Chimney height should comply with relevant standards. Chimneys should be added raincap and smoke. Weight not directly on the boiler chimney host chimney 5, hydrostatic test shall be carried out after the installation of boiler water pressure test supervisor. Pressure test before proceeding to deal with internal boiler inspection, hydrostatic test pressure MPa, during hydrostatic testing, water pressure should slow down. When the pressure rises to 0.1MPa, the water pressure should be increased to 0.1MPa. When the ambient temperature is higher than 5C, hydrostatic test should be carried out; when the temperature is lower than 5, should be protected from freezing water pressure test. Hydrostatic test water is generally 20-70.6, should be as light fuel oil or gas oil (China) as the fuel, the fuel oil is generally heated to 100 deg.] C, a viscosity less 30E. Oil Qbw = 10200Kcal / kg LHV viscosity of the oil is lower than at 50 ℃ 200E, at less than about 80 ℃ 200E, 50e is less than the heat value of natural gas Qbw = 8550Kcal / kg LPG Qbw = 22000Kcal / kg.

Gas boiler room location should pay attention to these issues need to pay attention to the location of gas boiler room boiler room of a problem than how specific to the site, more customers just curious boiler room and other buildings safe distance, do have customers believe boiler room just fills the room, as long as the boiler plant went on line, do not need to sun and rain. But in fact, the boiler room location is very important, it is related to a series of questions of your initial investment and system planning, job handling and safety protection. With gas boiler, for example, for us to introduce issues related to pay attention to the orientation of the boiler room. 1, the orientation of the gas boiler room should be summarized gas type, boiler capacity, operating pressure, supply and return water temperature, the system in the form of building types and other factors to consider. 2, natural gas boiler room planning should be "boiler room planning norms" (GB50041-2008), "town gas planning norms" (GB50028-2006), "building plans for fire protection" (GB50016-2006), "the senior civilian in accordance with existing national norms architectural plans for fire protection "(GB50045-95) (2005), and" condensing hot water boiler boiler safety skills supervision "(labor pan word [1997] No. 7) are summarized concluded. If there are local with local codes, with the satisfaction to consider. 3, gas boiler room should be set in separate buildings on the ground, if the conditions are bound, connected to the main building or need to set up in the basement of the main building, semi-basement, while the first floor, the top floor and center floor, shall be approved by the local fire, safety supervision and environmental protection part of the agreement. 4, gas boiler room directly prohibit people gathered in the room (such as public baths, classrooms, auditoriums, shops, restaurants, waiting rooms, etc.) or at the top, bottom, or top lax immediate neighborhood of the mouth on both sides. 5, the new residence should not be connected to the boiler room, boiler room and other adjacent buildings, the wall adjacent to the firewall. Boiler room on the ground should be flat without steps, and should prevent accumulation of water. 6, because the conditions there are shackles, located in the basement boiler need, center or top floor high-rise buildings or multi-layer, prior consent of the city, prefecture-level and above safety watchdog agree. In addition to the above requirements satisfaction, it should also be satisfied: (1) each boiler rated evaporation does not exceed 4t / h, the vapor pressure does not exceed the rated 1.6MPa. (2) oil is necessary, as a fuel gas or electric heating boiler. (3) the fuel supply line adapter using welding backing. 7, as provided in the boiler room in the basement or the first half-layer or multi-layer high-rise buildings, it is necessary to fit together the following conditions: (1) each boiler rated evaporation does not exceed 10t / h, the vapor pressure does not exceed the rated 1.6MPa. (2) Each boiler necessary to have reliable overpressure protection device interlock and interlock the bottom level protection. (3) accessories and safety interlock protection device for each boiler to regular maintenance and experiments to ensure active, reliable. (4) the building structure between the boiler should be the appropriate seismic measures. (5) operating independently fireman fireman operating permits necessary to hold the appropriate level of boiler and continuous operation of the same class more than five years, has not had trouble occurs. (6) the need to have lax security channel.

18-20 May 2017, ISH heating HVAC industry event successfully held in Beijing International Exhibition Center. Fast boiler latest on-line premix vacuum condensing hot water boiler boiler landmark "Thalia T6" and coupled steam boiler, "Euromonitor θ5" series of products also opened a mysterious veil, show it to all visitors.

Gas boiler cook stove Note: As the boiler equipment kinetic energy sources in the manufacturing, transportation, installation and maintenance process will bring oil and other impurities, persist in the boiler, it will not only clog water pipes, deteriorating the quality of steam, but also will reduce the heat transfer effect, the heating surface prone to overheating cause burn. Therefore, for removing impurities boiling out this step, the stable operation of the boiler is an integral part.
