FIREWOOD BOILER INCLUDING HORIZONTAL BRIQUETTE PLACEMENT TYPE HEXAGONAL HEATING DUCT

摘要

Disclosed is a firewood boiler including a horizontal briquette placement type hexagonal heating duct. The present invention relates to a briquette assisting type firewood boiler keeping heat of hot water in a water talk for a long time, capable of preventing a rapid temperature drop of hot water in a water tank through heat of briquettes, properly delayed to be ignited by a briquette combustion control panel, since combustion gas flows around the outer surface of the briquettes as the briquettes are horizontally placed in the hexagonal heating duct. The hexagonal heating duct secures structural hardness to bear strong heat. An upper ∧-shaped part of the duct prevents the duct from being curved or drooped by the weight of the hot water in the water tank. A lower V-shaped part prevents the duct from being curved or drooped by the weight of the briquettes, and also makes pyroligneous liquor discharged under the horizontally placed briquettes along a discharge groove forming a natural gradient in a range of 1-5 degrees. Therefore, the present invention is capable of solving a problem that hot water becomes rapidly cool in the morning as combustion is finished early due to a shortage of additional firewood even though firewood was full in a common firewood boiler in the evening.;COPYRIGHT KIPO 2016
