Waste heat recovery-type dirt retention-prevention oil burning boiler

Abstract

The invention discloses a waste heat recovery-type dirt retention-prevention oil burning boiler. The oil burning boiler comprises a burner and a boiler body, wherein a waste gas pipe of the boiler body is sequentially connected with tube passes of a water preheater and an air preheater and then is exhausted; a water inlet pipe of the shell pass of the water preheater is connected with a head tank, and the water outlet pipe of the shell pass of the water preheater is connected with a water inlet connector of the boiler through a water pump and a valve; the air inlet pipe of the shell pass of the air preheater is communicated with the atmosphere, and the air outlet pipe of the shell pass of the air preheater is connected with the burner; each blade of a centrifugal fan impeller of the burner is of a hollow inverted-drop shape. According to the waste heat recovery-type dirt retention-prevention oil burning boiler disclosed by the invention, heat in the waste gas of the boiler is effectively recycled for twice, so that consumption of diesel fuel of the burner is lowered; each blade is of a hollow inverted-drop shape, so that dirt on the centrifugal fan impeller of the burner is cleaned in real time; besides, the strength of the fan impeller is increased, so that the service life of the equipment is prolonged, and safety accidents caused by dirt retention can be effectively eradicated; and the application prospect of the waste heat recovery-type dirt retention-prevention oil burning boiler is wide.

Description

technical field [0001] The invention relates to an oil-fired boiler, in particular to a tail heat recovery type dust-proof oil-fired boiler. Background technique [0002] Boilers are very commonly used thermal power equipment. Oil-fired boilers are very environmentally friendly boilers due to their complete combustion, no smoke, perfect automatic control system, and exhaust emissions that can meet the environmental protection requirements of exhaust emissions in residential areas. They are widely used in high environmental protection requirements. occasions. [0003] The main body of the burner and the boiler is the core component and main equipment of the oil-fired boiler. The main structure of the burner is composed of a centrifugal fan and other auxiliary equipment. The continuous, stable and reliable work of the burner and the centrifugal fan is very important. Most of the places used contain a certain amount of dust. When the burner and centrifugal fan are working, whe...

Problems solved by technology

Once some hardened dust is shaken off by vibration, it will immediately leave the dynamic rotation balance of the fan, and then generate strong vibration, which may cause serious personnel and equipment safety accidents
