Description

Technical Field

[0001] The utility model relates to the technical field of boiler devices, in particular to a high-efficiency heat-exchange pulverized coal boiler device. Background Art

[0002] A pulverized coal boiler is a new type of coal-fired industrial boiler centered around "pulverized coal combustion technology." It uses pulverized coal ground to a certain fineness as fuel, and through an efficient combustion and heat exchange system, converts the thermal energy in the pulverized coal into steam or hot water. The pulverized coal particles are uniform and burn suspended in the air, resulting in a low combustion-air ratio, a high burnout rate, and minimal heat loss from flue gas emissions. Pulverized coal boilers utilize fully enclosed pulverized coal delivery, air supply, and ash removal technology, offering excellent thermal insulation and reducing heat loss from hot air and flue gas leakage. They also have low pollution emissions and meet environmental protection requirements. Pulverized coal boilers can adapt to different types of fuel and operating environments, demonstrating strong adaptability and stability. Existing pulverized coal boilers typically add pulverized coal through a feed port on one side for combustion. Existing pulverized coal particles are larger, so adding them directly to the boiler for combustion is inefficient.
