The invention relates to hot-air central heating equipment, particularly to a
coal-fired hot-blast stove. The
coal-fired hot-blast stove comprises a stove body, wherein a heat-exchanging device is arranged in the furnace chamber of the stove body; a
combustion chamber is arranged at the lower part of the stove body; a
smoke dust catcher is connected with a
tail gas outlet at the middle part of the stove body; a hot-air outlet is arranged on the side wall of the
combustion chamber; and a secondary air inlet is further arranged at the top of the stove body. As the secondary air inlet is arranged at the top of the stove body, the
coal-fired hot-blast stove in the invention achieves sufficient air feed and full
combustion, solves the problem of
flue waste caused by insufficient combustion fundamentally and reduces the cost. Furthermore, the hot-air central heating equipment has the characteristics of compact structure, reasonable
layout, large heat-exchanging strength, fast temperature rise speed,
high heat efficiency, small occupied area, convenience for installation and operation, clean air hot, stable properties and the like.
