Split-type liner heating oven stove

Abstract

The invention relates to a split-type liner heating oven stove, which comprises a firewood inlet, a stove body, a smoke box, a fire cover and a base. A split-type liner and an oven are installed in the stove body. One side of the split-type liner is connected with the firewood inlet and the other side of the split-type liner is close to the oven. A firing smoke duct is formed between the oven and the fire cover. A return smoke duct is formed between the oven and a base cover plate. A smoke guide plate is arranged in the return smoke duct. A smoke inlet is arranged at the lower part of the smoke box. The split-type liner heating oven stove provided by the invention has the advantages that since the split-type liner is adopted, an upper liner which is usually apt to be damaged can be replaced conveniently when the upper liner is damaged; since the split-type liner is close to the oven, the internal temperature of the oven is convenient to increase and the baking of food is facilitated; and at the same time, since the split-type liner is close to the oven and a smoke baffle and the smoke guide plate are matched to limit the flowing of high-temperature smoke on the side, the situation that the temperature of the side close to the smoke box is higher and the temperature of the side far away from the smoke box is lower is avoided.

Description

technical field [0001] The invention relates to a civil heating furnace, in particular to a split-type inner tank heating oven. Background technique [0002] Most of the existing heating furnaces have an integrated furnace liner. Since the furnace liner is made of metal, the furnace liner will be deformed and scrapped after long-term use. It is inconvenient to replace the integrated furnace liner, and the cost is relatively high. The flue gas of the existing air return type heating furnace is mostly directly discharged into the chimney from one side of the smoke box, and the temperature at the side of the firewood inlet is relatively low, which is not conducive to heating. Most of the existing heating furnaces with ovens are equipped with the oven outside the furnace body, which is inconvenient for processing. It is necessary to cut out multiple pieces of special-shaped plates, which increases the workload, and it is difficult to maintain a good appearance due to the many we...

[0002] Most of the existing heating furnaces have an integrated furnace. Since the furnace is made of metal, the furnace will be deformed and scrapped after long-term use. The integrated furnace is inconvenient to replace and the cost is high.

Existing air return type heating furnace flue gas is mostly discharged directly into the chimney from the side of the smoke box, while the temperature at the side of the firewood inlet is relatively low, which is not conducive to heating

Most of the existing heating furnaces with ovens set the oven outside the furnace body, which is inconvenient to process, and requires cutting out multiple pieces of special-shaped plates, which increases the workload, and because there are many welds on the outer surface, it is difficult to maintain a good appearance
