Steam boiler maintenance sewage
The discharge of steam boilers is essential and often used in the normal operation of the boiler room and in the routine maintenance. The main purpose of the steam boiler is to control and reduce the solid impurities in the boiler water. The discharge of the steam boiler can reduce the inside of the boiler, because the scale of the boiler causes the corrosion of the inner wall of the boiler. Below, we will introduce the main method of steam boiler blowdown.
There are two main ways of discharging sewage from steam boiler: continuous discharge and manual discharge
The continuous discharge of the steam boiler is called continuous discharge, and the calibration valve and the discharge valve close to the surface of the boiler water are used. The principle is to draw water from the top level of the boiler at a predetermined rate of water intake. Continuous discharge is an optional function in daily maintenance, but all steam boilers should have a manual discharge device.
Manual discharge of steam boilers is also called manual discharge and manual discharge is done through the opening in the bottom of the hearth. These small openings are specifically designed to remove scale deposits on the inner wall of the boiler. Manual discharge is also intended to filter out some precipitated impurities or other sediments in the water. Regardless of whether the boiler has a continuous drain system, all steam boilers should be equipped with manual drain.
