Problems solved by technology
[0004] The larger assembled boiler base has a larger volume, especially the width will exceed the normal limit width of railways and roads, which will bring difficulties to transportation. Even if it exceeds a certain width, it can be transported, but it will also increase a lot of transportation costs

Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with accompanying drawing:
[0016] According to the existing structure commonly used in the industrial boiler industry, fast-installed boilers of 4t / h and below 4t / h generally adopt the air intake method at the bottom of the grate: the primary air from the air preheater etc. The vertical underground ventilation pipe in the foundation on one side of the boiler is about in the middle of the boiler and then enters the lower part of the boiler grate horizontally. There is a large space under the boiler grate through which the primary air is distributed to one side of the grate or On both sides, the primary air is distributed to each air chamber in the longitudinal direction of the grate by the air regulating doors arranged on one or both sides of the grate longitudinally, so as to achieve the purpose of segmental air supply in the longitudinal direction of the grate. (See figure 1 ).

The invention relates to a grate-fired grate (with an assembled base) for coal-fired industrial boilers and an assembling method thereof. The grate-fired grate comprises stand columns, a grate, joist steels and a structural steel, wherein the stand columns on both sides of the grate are arranged on two joist steels at the bottom of the grate, and two joist steels on both sides of the grate are connected and fixed through the structural steel; the grate is arranged on the structural steel connecting the two joist steels, and two air ducts are formed between two side plates of the grate and an outer protective plate of a grate base; and the assembling method comprises the following steps: firstly, welding the stand columns on both sides of the grate on two joist steels at the bottom of the grate; then, connecting and fixing the joist steels welded with the stand columns on both sides thereof by using the structural steel, and installing the assembled grate on the structural steel; and finally, installing parts of an adjustable damper and top plates of the air ducts. The grate-fired grate disclosed by the invention has the advantages that: a base of a large grate is installed in an assembling mode changed from a complete installation mode, thereby solving the problem that the base is superwide in the process of transportation; and by using an air inlet structure designed in the invention, the area of an air inlet is further increased, so that the air inlet completely can meet with the air feeding requirements of grates.
Description
technical field [0001] The invention relates to the field of coal-fired industrial boilers, in particular to a layer-fired grate of a coal-fired industrial boiler with an assembled base and an assembly method. Background technique [0002] The air intake mode of the floor-fired grate of coal-fired industrial boilers (including chain grate and reciprocating grate, etc.) is related to the structure of the boiler grate and the layout of the boiler room, and has an important effect on the operation of the boiler and the combustion conditions of the boiler. Impact. [0003] Coal-fired industrial boilers can generally be divided into quick-pack boilers of 4t / h and below 4t / h according to boiler capacity; assembled boilers below 20t / h and bulk boilers of 20t / h and above 20t / h (some boiler manufacturers There are also three types of boilers with a capacity of about 20t / h that are assembled). Due to the different structures of these three kinds of boiler grates, the ways of enterin...
