A heated boiler is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .
Measures to improve the thermal efficiency of the fuel gas-fired boiler wns type of chemical oil-fired boiler which is incomplete combustion heat loss and mechanical incomplete combustion heat loss. Because almost no ash after combustion of the gas boiler, solid and liquid fuels without mechanical incomplete combustion, there is no need to consider the mechanical incomplete combustion of the gas boiler heat loss. In all heat losses, heat losses have tremendous proportions, when the high thermal efficiency of boilers, heat losses so the total loss of the main heat losses of fuel gas-fired boiler flue gas heat loss is the exhaust gas temperature and For air excess factor. When the exhaust gas temperature decreases, high thermal efficiency can be obtained, for example, a conventional three-pass wns 2 ton fired steam boiler, furnace used in the past straight and smooth smoke tube, must increase the heating surface is arranged to make the exhaust gas to an acceptable degree, the theoretical discharge around the smoke heat loss. Potshell causing significantly increased diameter, wall thickness increased, greatly increased metal consumption, thus further reducing the exhaust gas temperature should be greatly restricted. From the aspect of heat transfer is not only now consider only the heated area, the use of new technology enables heat transfer performance significantly increased, the difference between the heat transfer overcomes the disadvantages of the past performance of the boiler, so that the exhaust gas temperature decreases, the structure is more compact. Center back boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas wns improve thermal efficiency of the boiler as the oil, gas fuel burn easily wns type gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature. Separation type condensing gas boiler is out of the main boiler heating surface, the installation of the condensing heat exchanger. In one aspect of the flue gas absorption can significantly reduce the smoke temperature, reducing heat losses, on the one hand the absorption of part of the potential condensing water vapor released, increasing the effective use of heat of the fuel. Ash cleaning, to ensure that the heating surface of the scale wns boiler thermal efficiency of the boiler, the presence of soot fouling and heat transfer resistance increases, reducing the heat transfer effect. The thermal conductivity of the scale and soot is almost of the same order of magnitude, with the increase in scale, soot, the exhaust gas temperature rapidly increases, the thermal efficiency is significantly decreased. So, keep the boiler heating surface inside and outside clean, efficient heat transfer, thermal efficiency and to ensure the safe and economic operation of boilers, boiler fuel gas-fired boiler ash cleaning is required.
