The invention discloses a heating device using
solid fuels, and belongs to the field of civil heating furnaces. An air
distribution system achieves an upper way and lower way of independent and adjustable air supplying, the
furnace temperature is controlled to be within a reasonable interval, the burning efficiency can be significantly improved, the content of
oxygen in a
hearth can be accuratelyadjusted, thus it is guaranteed that the interior of a furnace is always in an optimal burning state, and the superior burning efficiency and the better emission reduction effect are achieved; and a
control system can set different air distribution schemes including the air distribution proportion and the total
air volume according to burning properties of the different
solid fuels and can furtherreal-timely adjust the air distribution proportion and the total
air volume according to CO content and the temperature change fed back by a detection unit, and thus it is guaranteed that the
solid fuels are always in an optimal burning state in the burning process, wherein the solid fuels especially refer to
coal. Through the scheme of adaptively adjusting the air distribution proportion and thetotal
air volume, different
combustion-supporting
modes are given to the different types of fuel
coal so that the optimal burning and optimal emission effects on the fuel
coal with different properties can be achieved.
