Energy-saving type coal-fired boiler with scale removal heating for heating

Abstract

The invention relates to an energy-saving type coal-fired boiler with scale removal heating for heating. The energy-saving type coal-fired boiler with the scale removal heating for the heating comprises a supporting plate, a drum and four supporting frames, and further comprises a scale removal mechanism and a waste heat mechanism; the scale removal mechanism comprises a first motor, a rotating shaft, a rotating box, a lifting assembly, two cleaning plates and two connecting assemblies; the connecting assemblies comprises connecting rods, moving plates, springs and bracket plates; and the waste heat mechanism includes an air exhaust assembly and a radiating tube. According to the energy-saving type coal-fired boiler with the scale removal heating for the heating, the inner wall of the drumcan be subjected to scale removal work through the scale removal mechanism, the influence on the heat conduction efficiency of the drum due to the fact that the scale covers the inner wall of the drum is avoided, the heat of gases discharged from the coal-fired boiler after fire coal is burned is used for heating cold water in a water inlet tube through the waste heat mechanism, and the energy saving of the coal-fired boiler is improved.

Description

technical field [0001] The invention relates to the field of heating equipment, in particular to an energy-saving coal-fired boiler for heating with descaling and heating. Background technique [0002] A coal-fired boiler is a boiler whose fuel is coal-fired. It refers to the burning of coal in the furnace, releasing heat, heating the heat medium, heat medium water or other organic heat carriers (such as heat transfer oil, etc.) to a certain temperature (or Pressure) thermal power equipment, often used in people's daily life heating. [0003] After the existing coal-fired boiler is used for a long time, the inner wall of the boiler is easy to form scale, which reduces the heat transfer efficiency of the coal-fired boiler and greatly reduces the energy utilization efficiency. Not only that, the temperature of the air discharged from the outlet pipe of the boiler Higher, directly discharged into the atmosphere, resulting in heat loss, reducing the energy saving and environmen...

Problems solved by technology

[0003] After the existing coal-fired boiler is used for a long time, the inner wall of the boiler is easy to form scale, which reduces the heat transfer efficiency of the coal-fired boiler and greatly reduces the energy utilization efficiency. Not only that, the temperature of the air discharged from the outlet pipe of the boiler Higher, directly discharged into the atmosphere, resulting in heat loss, reducing the energy saving and environmental protection of coal-fired boilers, thus greatly reducing the practicability of coal-fired boilers
