Which is better, the diesel stove or the coal stove used in the hotel kitchen? Please tell me the advantages and disadvantages.

Hotels of a certain scale usually cook with diesel stoves. Generally, diesel vehicles can use both gas and diesel, but coal stoves are generally not used in kitchens or in hotel boiler rooms to burn steam.

Diesel oil is clean and convenient, but the price is higher and coal is cheaper, but it will be dirty in the kitchen.
