Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to the following examples.

[0031] Such as figure 1 As shown, the supercritical T-type boiler with a secondary reheater, the T-type boiler has a "Т"-shaped structure with horizontal flues arranged symmetrically or asymmetrically on the left and right sides of the upward furnace of the column and the outlet, and the horizontal flues are respectively Connected with the downward convection flue, the left and right sides of the T-shaped boiler are equipped with folding flame angles, which make the air flow more stable. From the direction of the flue gas flow, the flue gas flows out from the right outlet of the furnace, and flows through the right low-temperature superheater, the right high-temperature superheater, the primary reheat high-temperature reheater, the primary reheat low-temperature rehea...

Abstract

The invention discloses a T-shaped boiler with a reheater. According to the invention, the heating surface of the boiler comprises an overheater, the reheater and a coal economizer. In the T-shaped boiler, a column body uplink hearth and horizontal flues in symmetrical or asymmetrical arrangement at the left side and the right side constitute a T-shaped structure; the horizontal flues are respectively connected with a downlink convection flue again; from a view of the flow direction of the flues, flue gas flows out of a left exit or a right exit of a hearth, and sequentially flows through a low-temperature overheater, a high-temperature overheater, an re-heated high-temperature reheater, a re-heated low-temperature reheater and the coal economizer; and the left side and the right side of the T-shaped boiler are both provided with furnace arches.

Description

technical field [0001] The present invention relates to a boiler with reheater for use in the power industry. Background technique [0002] In a power plant, a T-shaped boiler is a boiler composed of a column that goes up, horizontal flues arranged symmetrically or asymmetrically on the left and right sides of the furnace and its outlet into a roughly "Т"-shaped structure, and then respectively and the downward convective flue. [0003] In a power plant, the steam becomes relatively low pressure after doing work in the high-pressure cylinder of the steam turbine, is discharged from the high-pressure cylinder, enters the primary reheater of the boiler to be heated, and is supplied to the steam turbine for a reheating medium-pressure cylinder to perform work, then is discharged and enters the boiler It is heated in the secondary reheater and supplied to the secondary reheating intermediate pressure cylinder and low pressure cylinder of the steam turbine to do work. Such a the...
