The straw integrated stove takes cut straws as fuel, and the length of the straws is about 2 cm generally. The straw is preferably corn straw, and also comprises sorghum straw, bean straw, firewood and the like, but not limited to the above. The straw can generate strong energy, the energy is generated only according to the proportion of fluffiness of straw cutting sections and wind power, the wind power of a traditional hearth can be pumped away as soon as the combustion is greatly unequal, and the method solves the problem that the fire outlet is changed to the bottom side of the trend, fuel which passes through the fire outlet and is crushed and then light can be blocked and not pumped away during blanking, and the strong energy and the thermal efficiency can be doubled only when the wind power is suitable for the straw.

Referring to fig. 1, the straw integrated cooker comprises a cooker body 1, a hearth 3 is arranged in the left side of the cooker body 1, and two side-by-side cooking range openings 2 are not limited to the cooker body 1 (a ladle, a steamer, a kettle and other cooking utensils can be placed during cooking) or three cooking ranges are arranged on the right side of the cooker body 1. The cooking stove opening 2 is arranged at the right side of the hearth 3, the two are staggered, and a side channel 6 is arranged at the bottom of the hearth 3 and is communicated and connected with the bottom of the cooking stove opening 2, namely, is separated by a partition board 9. The right side of the cooking range opening 2 on the furnace body 1 is provided with a smoke exhaust pipe 5. The exhaust funnel 5 is connected with an induced draft fan. The crushed straw fuel in the hearth 3 is continuously fed into the hearth 3 through a hopper (a drawing is omitted, the conventional technology) beside the furnace body 1 and a movable chain scraper below the hopper, the speed is controllable, and continuous feeding and continuous combustion are guaranteed. The straw burns in the hearth, because the induced air effect, the flame is taken out below the cooking stove mouth 2 through the side passageway 6, and the firepower is very vigorous, and the thermal efficiency is high, and baffle 9 has blocked the straw fuel simultaneously, has avoided the straw fuel to be taken out away. The arrangement of the partition board 9 and the side channel 6 ensures that the furnace can use the crushed straws as fuel, the combustion effect is particularly good, and the heat efficiency is obviously improved.

When the crushed straw fuel is put into the hearth 3, the crushed straw fuel is put close to the left side of the hearth 3, the amount of the put-in straw fuel is preferably larger than the height of the side channel 6, and then the crushed straw fuel is ignited to continuously supply fuel, so that the fuel is kept to be burnt near the height of the side channel 6.
