Pressure switches and pressure gauges are used to control and read the pressure in the steam boiler. The reading obtained by the pressure switch is the reference used by the system to control the fuel to be released, seeking to maintain a certain vapor pressure in the system. Two pressure switches are normally used for this application.Get Price
Steam boiler pressure control. Steam boilers are used to heat up water in order to produce steam. Steam is widely used in the process industry for heating purposes. In this particular application, the steam was used to dry sludge in an installation in the Netherlands. The figure above shows a P&ID of the relevant installation.Get Price
