Description
Technical field
The utility model belongs to garbage burning boiler technical field, more particularly to a kind of steam air of garbage burning boiler
Pre-heating system.
Background technology
Power plant burns rubbish in the boiler, and the steam of generation is used to generate electricity and steam supply, is to have at present to garbage disposal
One of efficacious prescriptions formula, what is be widely used is fire grate type garbage incineration technology.On the one hand, generated electricity using the intrinsic calorific value of rubbish, be
A kind of measure turned waste into wealth, economized on resources;On the other hand, the landfill of rubbish has been greatly reduced, soil has not only been saved
Resource, even more greatly reducing pollution of the rubbish to environment.But, if rubbish is not sufficiently burned in boiler, it will
Produce a large amount of pernicious gases, not only can severe contamination environment, also increase discharge gas processing cost, while boiler efficiency also will
Substantially reduce.In order that the rubbish in boiler fully burns, the air temperature that need to will be fed into boiler brings up to 160 DEG C ~ 220
DEG C, because the flue gas produced after waste incineration generally has corrosivity, to avoid back-end surfaces from corroding, exhaust gas temperature one
As control more than 190 DEG C.If heating the method for First air using boiler smoke, it is serious to there is dust stratification in boiler air preheater
And the problem of low-temperature corrosion, cause the continuous hours of operation of boiler to be greatly reduced.
At present, boiler is preheated using steam-air pre-heating system more than garbage incinerating power plant, waste incineration and generating electricity
The steam-air heating system of factory is that boiler First air is carried out in advance using the steam of boiler-steam dome and the extraction of steam turbine exhaust section
Heat, specifically the amount of drawing gas and steam parameter are to be computed what is drawn by the economy of therrmodynamic system.Steam-air at this stage
It is evacuated more than heating system using two-part steam-air heater, as shown in Fig. 2 two-part steam-air heater bag
Include air channel case, be provided with high pressure section, the heat exchanger tube of low pressure stage in the case of air channel, the two ends of heat exchanger tube be equipped with the big header of import and export and

When gas is heated, high pressure section is drawn gas from boiler-steam dome, and low pressure stage is drawn gas from steam turbine steam discharge section, the condensation of high pressure section
Flash steam is added to low pressure stage by water after flashing apparatus to be continued to exchange heat, and is condensed moisture two-way and is transmitted back to oxygen-eliminating device.
There are the following problems during specific use for above-mentioned steam-air pre-heating system:1st, condensate is directly sent
Oxygen-eliminating device is returned, the energy of condensate is not utilized, and capacity usage ratio is low;Air is only added by high pressure section and low pressure stage
Heat, the efficiency of heating surface is not high;2nd, the horizontal arrangement of above-mentioned steam-air pre-heating system, floor space is larger, is unfavorable for the entirety of boiler
Arrangement;3rd, in above-mentioned steam-air pre-heating system, header, flashing apparatus etc. are all located in air channel, make air channel case bulky,
High-low pressure section is both needed to set the small header of import and export and the big header of import and export simultaneously, needs to consume substantial amounts of steel during manufacture, just
Phase investment is larger;4th, in above-mentioned steam-air pre-heating system, flashing apparatus has been used, and has condensed moisture two-way and has sent oxygen-eliminating device back to,
Whole system is complex;5th, in above-mentioned steam-air pre-heating system, the small header of import and export is arranged in air channel, header with
Welded between heat exchanger tube, angle welding is arranged in air channel, is colded and heat succeed each other and easily easily ftractureed using process, cause boiler
Blowing out.
Utility model content
The purpose of this utility model is providing a kind of steam air pre-heating system of garbage burning boiler, to solve two-part
In steam-air pre-heating system, the problem of efficiency of heating surface of air is low, capacity usage ratio is low.
In order to achieve the above object, base case of the present utility model is:A kind of steam air of garbage burning boiler is pre-
