Upgrading BKZ-75-39 type boilers of the Erdenet thermal power station by transferring it into in-furnace circulating fluidized-bed combustion of coal

The paper describes one of the methods for transferring meddle capacity installed boiler to fluidized bed combustion of coal. In this method, a circulating fluidized-bed is the furnace of the boiler that was simply and economically modified to use new types of coal that improves technico-economical characteristics and reduces the ecological pollution.
