DHL angle tube biomass boiler

Suitable fuels for corner tube biomass boilers: bulk straw fuel, formed biomass fuel. The fuel size generally requires no more than 50 × 30 × 10mm (length × width × thickness) or rod-shaped fuel with a diameter of mm × 30 × 50 (length × diameter), allowing a small amount of length of 50-100mm. The total moisture content is generally required to be no more than 25%, and the maximum is no more than 30%. For pressed fuel, the size is generally required to be no more than 30 × 30 × 10mm, and the total moisture content is generally required to be no more than 15%. When the moisture and ash content of the fuel are high, a reciprocating grate can be used. Special design: 1. The boiler body adopts a corner tube type and self-supporting structure, cleverly solving the related problems of boiler expansion and support. The support structure is simple and reliable. 2. The furnace and downstream flue are surrounded by fully welded membrane water-cooled wall structures, which have good sealing, low heat loss, and are clean and hygienic. 3. Both the air preheater and the economizer are manufactured in a box type structure, which can shorten the installation cycle and increase the sealing performance of the tail flue. 4. A boiler with a superheater is equipped with a flag shaped heating surface in front of the high-temperature superheater, ensuring the high-temperature performance of the superheater and enabling it to operate stably for a long time even in harsh flue gas environments generated by biomass combustion. When using a reciprocating grate, there is relative motion between the grate and the fuel, making it suitable for burning biomass bulk materials with high moisture and ash content and low calorific value. 6. When burning bulk materials, spraying is used to add them to the furnace, allowing the fuel to be burned in a mixture of "layer combustion+suspension combustion", resulting in high combustion efficiency. 7. Adopting a lightweight furnace wall structure, the overall weight of the boiler is light. 8. This boiler burns pure straw or other biomass without the need for additional bed materials .....
