Abstract

The application of the invention discloses a steam air preheating system of a waste incineration boiler. The steam air preheating system comprises a deaerator, an air duct box and a four-section type steam air preheater, wherein the four-section type steam air preheater sequentially comprises a high-pressure steam section, a low-pressure steam section, a high-pressure condensed water section and a low-pressure condensed water section from the top to the bottom, an outlet header of the high-pressure steam section communicates with an inlet header of the high-pressure condensed water section through a first pipeline, an outlet header of the low-pressure steam section communicates with an inlet header of the low-pressure condensed water section through a second pipeline, and draining valves are arranged on both the first pipeline and the second pipeline; and an outlet header of the high-pressure condensed water section communicates with an outlet header of the low-pressure condensed water section through a third pipeline, a pressure reducing valve is arranged on the third pipeline, and the outlet header of the low-pressure condensed water section communicates with the deaerator. Compared with the prior art, the system is high in energy utilizing rate and high in air heating efficiency. The system adopting vertical arrangement saves land occupying space and is favorable to the overall arrangement of the boiler.

Description

technical field [0001] The invention belongs to the technical field of waste incineration boilers, and in particular relates to a steam air preheating system of a waste incineration boiler. Background technique [0002] Power plants incinerate waste in boilers, and the steam generated is used for power generation and steam supply. It is one of the effective ways to deal with waste at present. The grate type waste incineration technology is widely used. On the one hand, using the inherent calorific value of garbage to generate electricity is a measure to turn waste into treasure and save resources; on the other hand, it greatly reduces the landfill of garbage, which not only saves land resources, but also greatly reduces Garbage pollution of the environment. However, if the garbage in the boiler is not fully burned, a large amount of harmful gas will be produced, which will not only seriously pollute the environment, but also increase the treatment cost of the exhaust gas, a...
