Oil gas boilers have obvious characteristics. The main fuel is oil or gas. According to their functions, they can be divided into steam boilers and hot water boilers. Most of them are designed with large furnaces, with thermal efficiency of more than 98%. At the same time, they also have the characteristics of fully automatic and safe operation. Shenyang Gas fired hot blast stove Generally speaking, oil and gas boilers adopt excellent boiler body design. WNS horizontal boiler adopts wet back three return structure, which can reduce the exhaust gas temperature and make the boiler thermal efficiency reach more than 90%. Therefore, the combustion efficiency is relatively high, greatly extending its service life. vertical Gas fired hot blast stove how much In addition, in the design of oil and gas boiler, there are often hinged front and rear smoke boxes. The maintenance method is simple. Most of them are insulated with light aluminum silicate fiber to reduce heat loss. The external use of all stainless steel plate skin improves the appearance quality. In addition, the oil and gas boiler is equipped with an excellent combustion machine, which greatly improves its stability. The combustion machine has an automatic purging function, It can also prevent deflagration during ignition.

Biomass boilers can be roughly divided into two categories according to their uses: one is biomass thermal energy boiler, and the other is biomass electric energy boiler. Shenyang Gas fired hot blast stove In fact, the principle of the two is basically the same. Both obtain energy by burning biomass fuel, which is just one way to directly obtain heat energy. The second way is to convert heat energy into electric energy. Among the two boilers, one is widely used and has mature technology. If we continue to subdivide, one kind of boiler - biomass heat energy boiler mainly has the following two types: one is small biomass heat energy boiler. vertical Gas fired hot blast stove how much The boiler uses solidified or gasified biomass fuel to provide heat energy in the form of hot water. Its advantages are small size, simple structure and low price; Class II: medium-sized biomass heat energy boiler. Such boilers mainly use solidified biomass fuel to provide hot water or steam. Its advantages are relatively mature technology, small energy loss and strong heat supply capacity.

The long-term use of gas-fired boilers will inevitably lead to problems of one kind or another. However, the working principle of gas-fired boiler is complex, and the price of gas-fired boiler is particularly high, so it is necessary to select high-quality gas-fired boiler manufacturers and companies with good after-sales service. Shenyang Gas fired hot blast stove In addition, what should we do if the gas boiler fails? As the gas-fired boiler involves the construction of gas and lines, the professional installation personnel of the manufacturer must check the installation at home, and the professional personnel shall install it. Improper installation will bring a series of problems for future use. vertical Gas fired hot blast stove how much The existing pipes and radiators in China need to be observed by professional engineers and installation personnel to determine whether they can continue to be used. If the service life is long, the heating system may scale more. It is generally recommended that the user replace it to obtain better heating effect.

High heat exchange efficiency. The fusion rate at the contact is more than 95%, the contact thermal resistance is small, and the thermal conductivity is good. Low flow resistance. Shenyang Gas fired hot blast stove Since H-shaped finned tubes are similar to square structures, after being assembled into heat exchangers, the tubes are divided into many small channels by fins, which has a certain uniform effect on the air flow. The air flow is similar to longitudinal downstream flow, and the air flow resistance is relatively small. However, spiral finned tubes have strong air flow disturbance, high turbulence, and large air flow resistance due to the directivity of the fins. Less ash. The flue gas contains fly ash, which is easy to deposit on the windward side and leeward side of the pipe bundle. The H-shaped fin tube bundle has the characteristics of flow equalization and downstream flow, which is not easy to cause serious local ash deposition, and the fly ash can be taken away with the air flow in time. Therefore, compared with spiral finned tube heat exchanger, H-type finned tube heat exchanger has less ash deposition. vertical Gas fired hot blast stove how much Small size and low weight. H-shaped finned tube has high area expansion rate, less ash deposition, and high heat transfer efficiency. When the heat transfer capacity is equal, the space occupied by the heat exchanger can be small. For reconstruction projects, the heat exchange area can be arranged as much as possible in the limited space to reduce the exhaust gas temperature, improve the waste heat recovery efficiency, or increase the maintenance space to facilitate maintenance.
