Recently, China's 21th National Assembly HVAC academic year in "Swan City" - Sanmenxia City, Henan Province began. This annual meeting embodies the HVAC industry leading experts, technical design schools scientists, representatives of major HVAC manufacturers and industry media, nearly 20,000 HVAC colleagues attended the meeting.

Electric heating electric boiler heating boiler depends on the configuration simple heating pipe coupling method chosen triangle, three heating pipes are combined into groups, consists of a rear cover, the union set union and electrical equipment coupled with the outside world, heating pipe with an electric group setting screen disadvantages body, heating process all material in the cylinder body carried out, indicating that electric tube group and show the outside world coupled electrical equipment, electric heating pipe group and show the outside world shows that electrical devices are linked, indicating that electric tube group setting there are disadvantages layer electric screen, indicating that the heating process in all material shows that the cylinder body. No pipeline. Circuit boards show simplified under the inlet, water inlet and outlet (or vapor), valve, pressure gauge, drain valve and the wiring pads and the like. Electric heating boilers design principles selected metal hose electric heater heating water, immediately converted to electromagnetic energy (caused by water or steam). According to ignite without chemical energy is converted into energy, which do not produce oil and gas ignite need, they do not discharge harmful substances and embers, which is in line with the actual eco-friendly regulations.

The scaling of gas-fired steam boiler sale not only reduces the thermal efficiency of the boiler, but also increases the temperature of the heating surface of the boiler, causes damage to the heating surface, and even causes the explosion accident of the boiler. Therefore, the use of soft water treatment equipment, strictly according to the process operation of boiler feed water softening treatment equipment, control boiler feed water quality, can delay the formation of the scale. At the same time, it is very important to control the boiler scale in real time, master the boiler scale and clean the scale if necessary. Because the temperature of the gas-steam boiler body and the steam-water heat pipe system is higher than the air temperature in the boiler room, some of the heat is emitted through radiation and convection into the surrounding air. This becomes a loss of heat. Boiler Therefore, the heat loss should be reduced when the heat insulation and heat pipe system of the boiler are damaged or leakage is discovered. The increase in noise from gas-fired steam boiler burners is mainly due to the closure of the valve or insufficient oil intake in the oil path, blockage of the oil filter, or because of low inlet temperature, high viscosity or oil on the pump. Too high temperature; oil pump failure; fan motor bearing damage; due to dirty turbine impeller, the equipment is too loud. This failure occurs when a gas-fired boiler is in use and is not easy to atomize (heavy oil) because of the high viscosity of the oil; it is also due to cyclone and jet The distance between the nozzles is inappropriate; in addition, because the burner is worn or dirty; it is also due to the excessive heating temperature of the spare fuel tank, resulting in steam pumping the oil pump out of the oil pump; or because the oil in the oil boiler is hydrated. Gas steam boiler feed water contains a variety of impurities and calcium, magnesium and other scaling substances, the boiler will inevitably expand. The thermal conductivity of the scale is very low, so once the surface is polluted by the hot surface, the exhaust temperature of the boiler will increase, and the heat loss of the exhaust gas will increase due to the increase of the thermal resistance. The experimental data show that the heat loss of waste gas will be increased by about 2%-4% when 1mm oxide is formed on the heating surface of boiler. The thicker the scale on the heating surface of the boiler, the greater the thermal resistance, and the lower the thermal efficiency of the boiler.

Hot water boiler fuel oil hot water boilers brief automatic control system has a high-tech, with a number of security devices, water protection, overpressure protection, flame protection, abnormal pressure protection, over-temperature flue protection; structure using tech, having a body holding a small, compact and easy to install, easy to operate, automatically adjust the pressure of the fuel to the atomizing, a slight positive pressure of the combustion so that fuel combustion and then more fully, and to reduce the loss of the fuel gas discharge, modern industrial steam is the most convenient and most energy-efficient, environmentally friendly standard products. The need for comprehensive maintenance of the gas hot water boiler gas hot water boiler for normal use, to do regular inspection and maintenance, however, has been used for a three-year-old boiler, we must conduct a more comprehensive repair work. 1, carrying out comprehensive maintenance check, the first thing to be clear inside the boiler ditch and sludge, after using water to rinse these ditches and sludge. 2, the boiler for burning site, there will be a large amount of soot and fouling, but also in such substances when overhaul, the cleanup process. 3, because the gas hot water boiler is used in metal processing and production, but also a lot of contact with water or steam, it is inevitable there will be erosion situation, when the boiler overhaul, to the corrosion phenomena boiler maintenance treatment Finally, we need to do to level the boiler fire boiler use paint protection to prevent future corrosion conditions.
