Water Tube Boiler - Definition, Components, Working

The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.

Design for a S7-200-Based Boiler Temperature Cascade

This paper describes a boiler temperature cascade control system using PLC as the controller. Here, PLC is used to control the voltage across the resistance wire inside the heater (Control Parameter). This is done in order to regulate the water temperature at the outlet (Primary Parameter to Control) and the water temperature inside the hearth (Secondary Parameter to Control) of the boilers

Steam Boiler Control: In Depth - Electronic Control

Modern Boilers come with a three-element-control that senses the amount of flow of steam. The electronic controller makes calculations for steam output in lbs/hr that directly correlates to the flow of water in gal/min to produce the required amount of steam. This is an algorithm within the PLC.
