Abstract

The invention discloses a kind of heat recovery steam generators, including afterheat steam shell, one end side of the afterheat steam shell is hot air intake, the other end is heat outlet, the two sides of the afterheat steam shell are equipped with the baffle being spaced one by one, form snakelike hot gas path, the afterheat steam shell is equipped with more the second vertical steam water pipes in the two sides of hot gas path and center, the top of the afterheat steam shell is equipped with the second plenum chamber, the second steam water pipe is connected by pipeline with the second plenum chamber, the top of second plenum chamber is equipped with steam pipe, the steam pipe that goes out is equipped with steam valve.The present invention realizes the utilization to hot gas waste heat by heat recovery steam generator, substantially increases the utilization rate of the energy;Heat recovery steam generator directly generates steam to the second steam Water pipe heating using hot gas waste heat, and is sent into the storage of the second plenum chamber.

Description

A kind of heat recovery steam generator
Technical field
The present invention relates to a kind of heat recovery steam generators.
Background technique
Steam generator is the mechanical equipment for water being heated as using the thermal energy of fuel or other energy hot water or steam, Biomass fuel steam generator solves the castoff burnings such as stalk in agricultural production process using agriculture and forestry organic waste material as raw material Bring atmosphere polluting problem;Power is provided for industry and life instead of non-renewable resources, reduces non-renewable resources damage Consumption.
Existing gas steam generator generates resource not enough sufficiently energy utilization rate is low using upper to fuel Waste.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of heat recovery steam generators, to efficiently solve in background technique The problem of pointing out.
The technical solution adopted by the present invention is that:
A kind of heat recovery steam generator, including afterheat steam shell, one end side of the afterheat steam shell are hot gas Import, the other end are heat outlet, and the two sides of the afterheat steam shell are equipped with the baffle being spaced one by one, form snakelike hot gas Channel, the afterheat steam shell are equipped with more the second vertical steam water pipes in the two sides of hot gas path and center, The top of the afterheat steam shell is equipped with the second plenum chamber, and the second steam water pipe passes through pipeline and the second plenum chamber phase Connection, the top of second plenum chamber are equipped with steam pipe, and the steam pipe that goes out is equipped with steam valve.
Preferably, second plenum chamber is equipped with safety valve and pressure gauge.
Beneficial effects of the present invention:
1, the utilization to hot gas waste heat is realized by heat recovery steam generator, substantially increases the utilization rate of the energy;
2, heat recovery steam generator directly generates steam to the second steam Water pipe heating using hot gas waste heat, and is sent into second Plenum chamber storage.
Detailed description of the invention
Fig. 1 is vertical view schematic diagram of internal structure of the invention;
Fig. 2 is the longitudinal sectional view of Fig. 1.
Specific embodiment
The present invention is described in further detail below by specific embodiment and in conjunction with attached drawing.
A kind of heat recovery steam generator as described in Fig. 1,2, including afterheat steam shell 31, the afterheat steam shell 31 One end side be hot air intake, the other end is heat outlet, and the two sides of the afterheat steam shell 31 are equipped with to be spaced one by one Baffle 32, forms snakelike hot gas path 33, and the afterheat steam shell 31 is equal in the two sides of hot gas path 33 and center Equipped with more the second vertical steam water pipes 34, the top of the afterheat steam shell 31 is equipped with the second plenum chamber 35, described Second steam water pipe 34 is connected by pipeline with the second plenum chamber 35, and the top of second plenum chamber 35 is equipped with steam pipe 24, the steam pipe 24 that goes out is equipped with steam valve 25.
Second plenum chamber 35 is equipped with safety valve and pressure gauge.
The working principle of the invention: hot gas enters from the side of heat recovery steam generator one end, in hot gas path 33 Second steam water pipe 34 is heated, and the steam that the second steam water pipe 34 generates enters in the second plenum chamber 35 from top, hot gas It is come out from the other end of heat recovery steam generator 3, the steam in the second plenum chamber 35 is discharged by the steam pipe 24 that goes out at top.
