NOVELTY - A high efficiency straw gasification furnace comprises furnace body (1), pressure rod (2), furnace cover (3), ash hole (4), charging opening (5), air outlet (9) and blower (6).    USE - The high efficiency straw gasification furnace is useful for optimizing air supplying mode in the furnace.    ADVANTAGE - The present invention provides a high efficiency straw gasification furnace which optimizes the air supplying mode in the furnace, has good air producing quality, much air producing quantity, high combustion ratio and high heat utilization ratio. It can recycle tar oil, etc.    DETAILED DESCRIPTION - A high efficiency straw gasification furnace comprises furnace body (1), pressure rod (2), furnace cover (3), ash hole (4), charging opening (5), air outlet (9) and blower (6). The swirl air furnace core (7) is equipped in the furnace body (1). The middle part of swirl air furnace core (7) is a short direct pipe (71). The upper end of short direct pipe (71) is sealed and opened with at least three ventilation holes (72) along with the circle direction equally. At least three long direct pipes (73) are equally distributed on the external pipe by spoke shape. One end of every long direct pipe (73) is connected with short direct pipe (71), and another end is sealed. The corresponding position on same side of every long direct pipes (73) is opened with more than three holes (74) along with the pipe. The swirl air furnace core (7) is connected with the blower (6) by vent pipe (8).
