Abstract
The utility model relates to a boiler. An inner container is arranged inside a boiler hood. A heat exchanger and a hearth placed below the heat exchanger are arranged inside the inner container. A water storage cavity is formed between the boiler hood and the inner container, the lower end of the water storage cavity is communicated with a water inlet, and the bottom of the water storage cavity is communicated with a water drain pipe. A fire grate is arranged below the hearth, the lower portion of the fire grate is communicated with a slag cavity, and a slag opening is formed in the side face of the slag cavity. A boiler drying device is arranged above the hearth, and a heating cavity which is communicated with the water storage cavity is formed in the boiler drying device. A heat exchange cavity is arranged above the boiler drying device, the heat exchanger is arranged inside the heat exchange cavity, and the heat exchanger is composed of heat exchange tubes which are vertically communicated with the water storage cavity and the heating cavity. A flame path which is communicated with the hearth and the heat exchange cavity is arranged between the boiler drying device and the inner container. A coal firing opening which is communicated with the outside is formed in the side face of the hearth, an ash cleaning opening which is communicated with the outside is formed in the side face of the bottom of the heat exchange cavity, and a chimney which is communicated with the outside is arranged on the top of the heat exchange cavity. A water outlet is formed in the upper portion of the water storage cavity. According to the boiler, the boiler drying device is used for gathering heat, the heat exchange tubes are vertically arranged, so that the heat exchange effect is good, and due to the fact that the heat exchange cavity is separated from the hearth, heat efficiency is high.
