How to clean and install the boiler economizer? The economizer is one of the primary equipment of the boiler combustion system. Located in the winding flue at the tail of the boiler, Economizer it uses the heat of the tail flue gas to heat the boiler feed water. The heat exchange equipment should be sturdy and the flatness of the school pipe should not be greater than before assembly. The error of 5mm setting-out dimension is not more than 1mm. Stop setting-out according to the drawing on the pipe calibration channel, Economizer and stop correcting where the outline dimension of the pipe row does not match the drawing.
Then, the installation order is the low temperature section-the medium temperature section-the low temperature section to stop the construction from bottom to top, that is, Economizer the monolithic hoisting assembly welding is used. Before the serpentine tube row is formally in place, Economizer first align and fix the support beams and headers, Economizer and then install two rows in the middle of each row in the width direction. If the component is wider and the middle part can also be installed with a row of serpentine tubes as the reference tube, Economizer then It is necessary to install anti-falling nets around the construction. The distance of each layer of anti-falling nets shall be implemented in accordance with safety standards, Economizer and the nozzles of the economizer serpentine pipes shall be temporarily blocked after passing through the ball. There should be anti-skid and anti-collision methods when hoisting.
