Honeycomb coal is a type of coal product that exhibits a honeycomb-like structure consisting of many small holes. This structure gives honeycomb coal a large specific surface area, which provides more contact area and facilitates combustion and gas adsorption. Honeycomb coal is usually used in gas purification, catalyst carrier and other fields. And lump coal refers to a form of coal, which is a lump made from raw coal after processing and compression. Coal briquettes are usually used for energy supply, such as power generation and heating. The form and size of coal briquettes can be adjusted as needed to fit different combustion equipment and needs.
