ABSTRACT:
A novel steel construction solid-fuel firing boiler for civil heating applications comprises a space portion defined by side, bottom, cover, front and rear walls forming therein an interspace for water to be heated, a firestone block burner in the space portion separating a fuel containing upper zone and a lower zone where a flame extends and flue gas is conveyed, the burner defining at a top face thereof a housing with a bottom hole for communicating the upper and lower zones and accommodating therein a refractory material body having a structure for holding overlying embers. The housing bottom and the refractory material body define a channel opening at the hole and communicating with an air distribution chamber in the front wall for conveying secondary combustion air. The boiler further comprises an electric fan with an automatic control circuit and primary and secondary combustion air outlet in communication with the upper zone and the distribution chamber, a smoke box, a loading door on the front wall, an inspection door and a communication port between the upper zone and the smoke box closed by a manually operated gate.
