Kara - Ecofriendly Green Boiler

The boiler at TDM is at the heart of the company's manufacturing operation and is an example of elegant efficiency. It provides heat and steam for drying timber and for powering certain manufacturing machinery, while at the same time helping to produce its own fuel. And it does this without releasing any harmful emissions into the atmosphere.
TDM's seven kilns are powered by this boiler, and each can dry 100 cubic metres of timber in as little as five days. The heat and steam the boiler produces also drives the factory's wood laminating presses, which produce shelving and the company's Techform composite product from small pieces of salvaged wood that would otherwise have no practical use. Its furnace lives off the scraps the factory can't use and with the aid of sensors to carefully control its internal temperature, the furnace's chimney emits little more than excess heat. Although it devours up to 800 kilograms of wood every hour, all that is left at the end of a shift is a single wheelbarrow of ash. Even the water the boiler it uses to produce steam is piped back after it condenses and is re-used.
