Abstract

The invention belongs to the field of thermal power boiler energy saving, and particularly relates to a fuel oil type full-automatic air heater. The fuel oil type full-automatic air heater mainly solves the problem that a fuel oil type heater is poor in safety and hot air temperature adjusting is not sensitive. The air heater mainly comprises a casting material fireproof layer, a second-stage combustion cylinder, a first-stage combustion cylinder, a control cabinet, an oil gun assembly, an electric adjusting valve, oil returning branch pipes, a compression air pipe joint and the like; smoke backflow formed by rotational flow pieces on oil nozzles is used for reinforcing combustion, multi-stage air distribution holes with the hole diameters gradually increased are used for achieving period-divided supplementing of the oxygen amount needed by combustion, the heat storage property of a heat storage cover is used for reinforcing the fuel oil gasifying, compressed air is used for sealing anoil gun casing pipe, oil gun online maintaining is achieved, online connection is used for adjusting the oil returning pressure to achieve automatic adjusting of force output of the oil gun, safety of fuel oil type air heating and hot air temperature controllability can be greatly improved, and the problem that an oil gun of the fuel oil type air heater cannot be subjected to online maintaining is solved.

Description

technical field [0001] The invention belongs to the field of thermal power boiler energy saving, and in particular relates to a fuel-fired fully automatic air heater. Background technique [0002] In order to save the oil consumption of thermal power boilers at cold start, my country's thermal power plants generally adopt micro-oil ignition and plasma ignition. and milling needs. However, the boiler cannot generate hot air through the air preheater at the initial stage of cold start, so it needs to use a specific method to heat the air to generate hot air. At present, there are two commonly used air heating methods, one is a steam heater, and the other is a fuel heater. The steam heater has the advantages of good safety and sensitive air temperature adjustment, but the disadvantage is serious corrosion. , high resistance, high cost, easy to leak, complex system, etc., while the fuel oil heater has the advantages of fast heating speed, simple and reliable system, and low cos...
