Industrial boilers are special equipment, and a series of installation operations are required before start-up. Everyone must not ignore this process, which is related to the safe and stable operation of the boiler in the later period. So what preparations need to be done before the installation of the industrial boiler? Let the technical engineers of Zhengzhou Fangkuai Boiler Factory answer for you.
First, check the completeness and accuracy of the boiler technical data, and register and file; prepare the technical documents for the construction; handle the boiler installation start-up report; count the equipment parts on site, register the missing parts, and fill in the main parts Quality inspection records; conduct site use of land, water, electricity, gas, and temporary construction; organize the entry of construction machinery and tools, etc.
Acceptance and marking of industrial boiler foundation: The installer shall inspect and accept the boiler foundation together with the construction unit, construction supervisor, and civil engineering personnel, and fill in the basic records; draw the vertical and horizontal centerline of the boiler, the elevation datum point and each foundation according to the coordinates of the drawing The position of the coordinate center.
Installation of industrial boiler steel frame and platform: check the number and external dimensions of the steel frame platform, fill in the record, adjust and correct if it exceeds the standard, and fill in the corrected actual delay in the record table; configure the foundation shim; bulk steel The frame is assembled into a piece, after passing the inspection, it is hoisted in place, and the steel beams are aligned, fixed, welded, and the geometric dimensions after welding are measured, and the steel frame installation records are filled in; the boiler foundation secondary grouting; the steel platform bracket installation.
Installation work of the heating surface of the industrial boiler body: the quality review of the drum and header, especially the quality of the account connecting hole, should be focused on inspection, measurement, and fill in the record, the quality of the heating surface tube, the quality inspection, measurement, and fill in the record; the heating surface Proofing, annealing and tube end treatment of the pipe; installation and fixing of the drum support and drum, and keep records; the hoisting of the header, correct, fix, and make a record; expand the pipe, strictly control the expansion of the pipe Quality, and make a record; before and after the expansion of the tube, each tube should be tested through the ball, and recorded and so on.
The assembly work of the industrial boiler water wall tube row: the piece welding and alignment of the water wall tube, the pass test before and after the welding, and make a record; the installation of the down tube.
Installation of industrial boiler superheater: calibration and ball passing test of superheater serpentine tube, and make records; installation, alignment, fixing and recording of superheater box; alloy of serpentine tube, pipe clamp and hanger Material spectrum analysis and inspection report of steel parts; group welding and geometric measurement records of serpentine pipes, hoisting in place, aligning and fixing, and filling in records of superheater installation.
