An energy-saving utility boiler

Abstract

The invention discloses an energy-saving power station boiler which structurally comprises a steam turbine, a coal-saving sleeve, a combustion chamber, a coal powder nozzle, an ash bucket and a flue gas recycling box, wherein the steam turbine is perpendicularly fixed at the top of a frame body of the combustion chamber and communicates with an internal pipeline; the coal-saving sleeve is mountedat the bottom of the right side of a bent tube of the combustion chamber; the coal powder nozzle is mounted at the top of the ash bucket and connected with the combustion chamber; the flue gas recycling box is fixed on the right side of the ash bucket; and the flue gas recycling box and the ash bucket are parallel to each other. In conclusion, the energy-saving power station boiler disclosed by the invention has the beneficial effects that the internal circulation speed is improved after the improvement, so that the sufficient combustion of fuel can be achieved; and at the position of the coal-saving sleeve, a turbulent wheel disc continuously and slowly rotates when sufficiently absorbing hot gas, so that the circumstance that the heat absorbing process is slow and the internal circulation is blocked due to the accumulation of coal slag on the surface of the turbulent wheel disc can be avoided.

Description

technical field [0001] The invention relates to the field of energy saving, and in particular discloses an energy-saving utility boiler. Background technique [0002] Power plant boiler is a kind of equipment that evaporates water flow into steam through heating and further makes steam drive steam turbine. It is usually divided into pulverized coal furnace and circulating fluidized bed and two kinds, but both of them need to install economizer at the end for heat Collect, but there are some problems during the heat exchange: [0003] The economizer as a whole passes through multiple steel pipes and then forms serpentine pipes through elbows, and finally connects them in parallel. It is installed at the bottom of the smoke pipe for collection, and they all adopt a fixed structure. During the process of collecting heat, the flue gas The suspended particles in the combustion chamber are cooled and attached to the surface, gradually causing the internal gas flow rate to slow do...

Problems solved by technology

[0003] The economizer as a whole passes through multiple steel pipes and then forms serpentine pipes through elbows, and finally connects them in parallel. It is installed at the bottom of the smoke pipe for collection, and they all adopt a fixed structure. During the process of collecting heat, the flue gas The suspended particles in the air are cooled and attached to the surface, gradually causing the internal gas flow rate to slow down, thereby affecting the combustion efficiency of the combustion chamber and causing more waste of resources
