In UK they like to have holes in the briquettes simply because of marketing purposes. The market has over the years been used to using screw extrusion briquettes, which has holes in them, because of the tip of the screw that naturally creates the hole. Thererfore we are often asked to supply briquetting lines that can make holes in the end product. Even though the briquettes are a little easier to ignite it is not due to practical reasons but in fact the are easier to market.
In other places they require more “special” shapes. For instance, in Italy many wood fired pizzerias use hard wood briquettes. They prefer to have angles on the briquettes to prevent the briquettes from rolling in the pizza oven. Therefore Triangle, square or octagonal briquettes are very popular here.
So the you see, the your options vary according to your wishes and your briquetting project.
