Energy-saving and environment-friendly distillation charcoal fire heating boiler

The invention relates to the technical field of heating boilers, and discloses an energy-saving and environment-friendly distillation charcoal fire heating boiler which comprises a boiler body, and an air inlet frame communicated with the interior of the boiler body is fixedly arranged in the middle of the boiler body, so that external air can enter the interior of the boiler body through the air inlet frame; and the dry distillation combustion assembly is used for fully combusting fuel and comprises a feed port which is fixedly embedded in the top of the boiler main body and is used for feeding materials into the boiler main body. Fuel at the bottom is combusted at the material receiving frame and is subjected to pyrolysis, dry distillation and gasification to generate tar, pyrolysis gas and semicoke, so that the unburned semicoke and pyrolysis gas are sufficiently combusted at the material receiving frame and are converted into coke, and then the coke is used for baking and heat dissipation, so that the sit
