Summary:The utility model discloses a briquette coal boiler which can reversely burn honeycomb briquette in lower-feeding and directly burn coal briquette in a normal mode. When the industrial honeycomb briquette is burned, a lifting mechanism and a limiting grate can finish a continuous reverse-burning mode of lower coal-feeding, upper-igniting and upper slag-exhausting. When the industrial coal briquette is burned, a lifting grate and the limiting grate can form a combined grate which is suitable for upper-feeding the coal briquette and can burn stably in a direct burning mode. The combined grate can adjust the primary air, the secondary air and a stove chamber stacked by fire-proof materials, and reliable guarantee is provided for the complete burning of the coal. Therefore, the product has the advantages of extensive coal-variety adaptability, high boiler thermal efficiency, smoke prevention and dust control.
