The furnace comprises a furnace body, a furnace door is arranged on the furnace body; an ash bin communicated with the outside of the furnace body is arranged on the furnace body below the furnace door; the opening direction of the ash bin is consistent with that of the furnace door; wherein a hearth connected with the furnace door is arranged in the furnace body, the furnace body comprises a furnace wall and a furnace top, the furnace door is arranged on the furnace wall and connected with the hearth, a high-temperature flue gas guide port is formed in the upper part of any side wall of the hearth, the furnace top is arranged at the top of the furnace wall in a sealing manner, and heat exchange sheets are respectively arranged outside the furnace wall and the furnace top. Coal energy can be replaced with biomass fuel, consumption of non-renewable energy sources is reduced, fuel consumption is low, limitationof a power source and weather is avoided, the temperature rising and heat exchange speed is high, air around the furnace body can be heated rapidly, the heat energy utilization rate is high, and heatlosses are effectively reduced. And compared with other types of heating modes, the cost is low, and energy is saved.
