YLW series thermal oil boilers are assembled forced circulation chain grate boilers. The front part of the biomass chain grate boiler body is the radiant heating surface of the furnace, which is composed of close-packed double-sided coils. The rear part is the convection scouring heating surface, which is composed of serpentine tube bundles. The boiler consists of an upper body and a lower chain grate, which are assembled on site.
The air preheater of the assembled chain grate boiler is arranged behind the boiler. The high-temperature flue gas generated by the combustion is absorbed part of the heat in the furnace, and enters the convection heating surface through the turning flue chamber to exchange heat. After exiting the boiler, the air required for the boiler combustion is heated in the air preheater, and then the air required for the boiler is heated by the induced draft fan through the dust collector. The flue gas is sent to the chimney and discharged into the atmosphere.
The thermal oil circulation system of the biomass chain grate boiler is a liquid phase closed circuit. The hot oil output by this series of boiler products is used by hot users (after heat exchange, all the heat is returned to the boiler through the system pipeline, avoiding the heat loss of condensation and blowdown of the steam boiler. It has obvious energy saving effect, so the heat utilization rate is high. The system does not require water treatment equipment, so the system is relatively simple, the boiler bears low pressure, and there is no risk of explosion due to organic carriers. Therefore, the entire system has less investment and the heating system is safer. There is less flue gas emissions, no pollution and heat pollution. The indicators (flue gas emission concentration and noise) are lower than the specified standard requirements.
Biomass thermal oil boiler uses biomass as fuel, so it has the characteristics of energy saving, environmental protection and high efficiency. In addition, the boiler itself has the advantages of high combustion efficiency, good heat transfer performance, safe and reliable operation, low operating cost, and high thermal efficiency. Therefore, it is very popular among customers. Biomass thermal oil furnace will not produce corrosion and dirt during operation, and will not produce exhaust gas. In addition, it has good heat transfer performance, convenient and quick maintenance, and high thermal efficiency. Therefore, it has become an instant It meets the policy requirements and also caters to the new boilers required by customers.
The biomass chain grate boiler has technical measures to strictly control the air, moisture and other low volatile content in the working medium before circulating heating. This series of thermal oil boiler has a complete operation control system and safety monitoring device, which makes the boiler operation easier and more convenient. During the operation of the boiler, the temperature of the boiler can be adjusted accurately according to actual requirements, which can meet the different requirements of customers.
