When you choose a DHB boiler, you are already leading the way to zero waste.
DHB boilers are products that allow the original waste energy to be reused. Biomass boilers and waste incineration boilers are able to burn the waste residue from production to produce new energy. Waste heat boilers produce steam from the hot or combustible medium in the working fluid, and generate electricity from waste gas and waste liquid as a heat source.
