The feed chamber 131 are arranged obliquely, the flame outlet 132 and the discharge port 133 are both communicated with the feed chamber 131, the cover pipe 110 is arranged on a periphery of the discharge port 132, and the grid 120 is arranged on the outside of the discharge port 133.

[0018] By burning the fuel placed in the feed chamber 131, the burning flame 132 is from the flame outlet, and the cover pipe 110 arranged on the periphery of the flame outlet 132 effectively blocks the direct contact between the outside world and the flame, effectively protecting safety of users, and the vertically arranged cover pipe 110 is conducive to guiding the flame to go up in a vertical direction. The flame in the particle heating landscape furnace 10 is more beautiful. Placing the particle heating landscape furnace 10 indoors can not only be useful for heating, but also be useful to decorate an indoor home environment. In addition, the feed chamber 131 is set inclined, which is beneficial to the fuel concentrated at a bottom of the feed chamber 131, and facilitates the combustion of the fuel. The flame outlet 132 and the discharge port 133 are arranged oppositely, which promotes the combustion of the fuel in the feed chamber 131. At the same time, the discharge port 133 is further conducive to the discharge of waste materials such as ashes after fuel combustion. The grid 120 arranged on an outside of the discharge port 133 prevents the fuel from falling, but does not affect the discharge of ashes and air flow.

[0019] In one embodiment, the cover pipe 110 is a glass tube. For the cover pipe 110 is a glass tube, a shape of the flame inside the particle heating landscape furnace 10 can be well seen because of the transparent nature of the glass tube, and, by selecting glass tubes of different colors, the flame is displayed through the glass tube in different colors, so that the flame generated by the particle heating landscape furnace 10 is more beautiful and different indoor atmospheres are created.
