AI Technical Summary
The existing biomass gasification steam boilers have fixed ash collection boxes, which makes it difficult to clean when the ash and slag are full. The ash and slag are also unevenly distributed, which can easily clog the ash outlet. In addition, the space in the ash collection box is not fully utilized.
A sliding ash collection box was designed and equipped with a scraping component, including a scraper and a dispersing rod. The scraper smooths the ash and the dispersing rod evenly separates the ash and slag. The ash collection box can be manually pulled out for cleaning.
This effectively avoids the problem of ash clogging the ash outlet, improves cleaning efficiency, and makes full use of the space in the ash collection box.
