Abstract

The invention relates to the technical field of constant pressure coal burning boilers, in particular to an environment-friendly and energy-saving constant pressure hot water boiler. The common hot water boiler at present has the following defects of large size, high manufacturing cost, inadequate fuel combustion, large heat loss, low thermal efficiency, vast dust discharge and severe environmental pollution. The hot water boiler consists of a preheating chamber and a combustion chamber, wherein the combustion chamber is divided into a combustion region and a coal-storing region by a water jacket partition wall; a convection tube is installed above the combustion region; a multi-stage return smoke tube passes through a preheating water jacket of the preheating chamber; high temperature gas and smoke dust pass through the return smoke tube to preheat cold water in the preheating water jacket; and the preheated cold water flows into the water jacket of the combustion chamber for heating. The fuel coal is subjected to dry distillation and then combustion in the coal-storing region so that the fuel is adequately combusted, and the thermal efficiency reaches 84%; and a dust chamber is arranged inside the boiler, and the dust in flue gas is kept inside the boiler. The invention has the advantages of small size, large coal-storing amount, high efficiency and energy saving and the emission lower than environment-friendly standard requirements.

Description

technical field [0001] The invention relates to the technical field of atmospheric pressure coal-fired boilers, in particular to an environment-friendly and energy-saving atmospheric pressure hot water boiler. Background technique [0002] Boiler is a kind of equipment widely used in industry and life. At present, most of the common hot water boilers use coal, coke, pulverized coal and other fuels to obtain energy. These boilers generally have the following disadvantages: the boiler is large in size, the manufacturing cost is high, the fuel in the boiler cannot be completely burned, and the released after combustion The heat energy produced cannot be fully utilized. A large amount of solid dust and high-temperature gas generated after fuel combustion is directly discharged into the air through the chimney. The temperature of the exhaust gas is as high as 300°C-400°C. Emissions such as these will pollute the environment and cause serious waste of resources. Contents of the...
