Embodiment 1

[0019] A joint structure system between pulverized coal boiler and side coal bunker in coal-fired power station, as attached figure 1 As shown, it includes a boiler 1, a coal bunker room 3, and a coal mill 5. The boiler 1 includes a boiler body steel frame 2, the coal bunker room 3 is a steel frame structure 4, and the coal bunker room steel frame 4 is connected to the boiler The main body steel frame 2 is connected, and the coal mill 5 is arranged in the steel frame 4 structure between coal bunkers. There are two boilers 1, and an independent coal bunker 3 and a coal mill 5 corresponding to each boiler are arranged between the two boilers, and the boiler body steel frame 2 of each boiler and its corresponding coal bunker Steel frame 4 connections. The steel frames of the two boilers are not connected to each other. The boiler 1 is type and tower type power station pulverized coal boiler.

Embodiment 2

[0021] A joint structure system between pulverized coal boiler and side coal bunker in coal-fired power station, as attached figure 2 As shown, there are two boilers 1, between which there is a coal bunker 3 used jointly by the coal mills 5 of the two boilers, and the steel frame 2 of the two boiler bodies passes through the steel frame 4 between the coal bunkers. Connected as a whole, the coal bunker room 3 is provided with two boiler coal mills 5 installation areas corresponding to the two boilers. For other references to Embodiment 1, details are not repeated here.

Abstract

The invention relates to a combined structure system between a pulverized coal boiler and a side bunker bay of a coal-fired power plant. The combined structure system comprises boilers, a bunker bay and a coal mill, wherein each of the boilers comprises a boiler body steel frame, the bunker bay is a steel frame structure, a bunker bay steel frame is connected with the boiler body steel frames, and the coal mill is arranged in the bunker bay steel frame structure. Two boilers are provided, the independent bunker bay and the coal mill, which correspond to each boiler, are respectively arranged between the two boilers, and the boiler body steel frame of each boiler is connected with the corresponding bunker bay steel frame. The steel frames of two boilers are not connected, or one bunker bay shared by the coal mills of two boilers is arranged between the two boilers, the two boiler body steel frames are integrally connected through the bunker bay steel frames, and two boiler coal mill mounting regions are arranged in the bunker bay relative to the two boilers. The combed structure system has the advantages of simple structure, good stability, investment saving, and capability of fully effectively utilizing a main power house space.

Description

technical field [0001] The invention relates to the technical field of coal-fired power station equipment, in particular to a joint structure system between a pulverized coal boiler and a side coal bunker in a coal-fired power station. Background technique [0002] The side coal bunker scheme of the domestic traditional coal-fired power station pulverized coal boiler adopts an independent structure between the coal bunkers. The basic feature of the coal bunkers is that the coal bunkers are set between two boilers, which is an independent structure, and there is no direct connection with the boiler steel structure. Connection relationship, and in order to save engineering cost, the independent coal bunker mostly adopts concrete structure, and there is a space between the steel structure of the boiler. The comprehensive cost of the boiler room and coal bunker room in this kind of coal bunker structure design scheme is relatively high, and the stability of the independent struc...
