Hot water boiler is one of the important equipment for the district to provide our real estate company, and two gas hot water provide the fast boiler boiler flotilla of environmental performance, in full compliance with state regulations after smoke was detected in the rear of the boiler. And boiler operation is safe, stable, we use the very at ease. --customer feedback
WNS0.7-1.0 / 115/70-YQ: Horizontal representative of the internal combustion type gas 50000 kcal automatic oil or fired hot water boiler, rated thermal power 0.7MW, Rated water pressure 1.0MPa, rated export / import water temperature 70 degrees Celsius and 115, respectively, fuel oil or gas. 1, rated thermal power: refers to the heat input per unit of time, common units kW kW or MW MW. There are some people to represent the output size of the hot water boiler tons.
Three tempering tube 50000 kcal automatic oil or fired hot water 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.
The main composition of gas-fired boiler: combustor sets electricity, apparatus, oil, gas in one. The high degree of integration and automation is the focus of boiler system maintenance. Boiler body: boiler body is the main component of the thermal energy conversion computer control system: computer control system is the core component of the whole boiler operation and the command center of the boiler. Maintenance of various systems: burner maintenance: clean burner rotor, ignition device, filter, oil pump, motor and impeller system, lube the valve connecting rod. Re-test combustion conditions. Controller maintenance: repair and inspection of electrical components, control Line, clean control box ash collection, each control point for inspection. At last, seal treatment is carried out. Prevent the controller element from getting damp. Maintenance of water supply system: maintenance of water treatment equipment, inspection of water quality standards, comprehensive cleaning of water treatment system, inspection of water pump operation and head, inspection of the flexible use of valves in each pipe, etc. Shut off the valve when the system is filled with water. Furnace maintenance: in order to keep the boiler safe and economical, the maintenance of boiler must be strengthened in daily use. This is also an important measure to prevent thermal efficiency decline, to avoid deterioration of service conditions and boiler accidents. Large font displays water temperature, square Water temperature from 10 ℃ to 90 ℃ can be set at will, the boiler automatically heating the system or to provide users with life, bath hot water. The control system controls the start and stop of the circulating pump according to the furnace water temperature. When the furnace water reaches the set upper water temperature, the hot water circulating pump starts, and when the set lower temperature is lower than the set lower temperature, the hot water circulating pump stops. The horizontal gas-fired bath boiler is a three-way full wet back structure. It adopts the design of large furnace and coarse smoke pipe to increase the radiative heat absorption of the furnace and effectively save energy and reduce consumption. The effect of heat transfer is greatly enhanced and fuel consumption is greatly saved by the use of threaded smoke tube and waveform furnace tank. The whole machine has been equipped at the same time. Thermal protection (when the water temperature in the furnace is super high, the burner automatically stops working and beeps to alarm, the secondary over-heat protection (when the boiler shell temperature exceeds 105 ℃, the secondary circuit is automatically cut off), and the protection against dry burning and water shortage (when the furnace water is lower than the very low water level, Boiler stop working and beep alarm), boiler leakage protection (control system detected electrical leakage, short circuit, will automatically cut off the power supply). The boiler is designed according to the normal pressure structure, the boiler is in no pressure state, and there is no danger of safety. High-grade centrifugal glass cotton multi-layer insulation, famous white color steel plate for external packaging, less heat loss, beautiful rust resistance.
