Boiler is a powerhouse of any process industry. Formation of scale and soot in boilers is still a great concern to increase the efficiency of the boiler. This paper presents a method for the soot blowing automation in a boiler using PLC. The important parameter to be monitored in each steam generator is the thermal efficiency or the heat rate.
DefinitionA PLC is a Programmable Logic Controller. In other words, it is an industrial computer used as a standalone unit and can be used in a network of PLCs to automatically control a process or perform a specific function. To take information from the outside world such as temperature of a liquid, level in a tank, speed of an object etc, PLC uses different forms of connected sensors.
Boiler Drum Level Control The purpose of the drum level controller is to bring the drum up to level at boiler start-up and maintain the level at constant steam load. A dramatic decrease in this level may uncover boiler tubes, allowing them to become overheated and damaged.
PLC-based control systems began to function like a mini-DCS. At the same time, the DCS hybridized to incorporate PLCs and PCs to control certain functions and to provide reporting services. The DCS supervises the entire process, much like the conductor in an orchestra. Protocols, like OPC, have eased interactions between the two control systems.

Unlike boiler systems, there are no mandated jurisdictional inspection programs for ovens and furnaces. 5. INTERLOCK TESTING. Burning fuel can be useful to mankind as long as it is done as a controlled process. Control means that combustion takes place where we want it, when we want it, and at the rate we want it.

Supervisory control and data acquisition (SCADA) software is a remote monitoring and control system that oversees automated processes in all kinds of factories. Manufacturers use SCADA to keep tabs on operations that require high-level supervisory control and real-time data acquisition.
This means a two-pump system requires an additional $800 of components over the purchase price of the PLC. User Interface PLC A PLC-controlled municipal pump station typically has a set of selector switches (for auto, off, manual [hand]) wired in, along with a set of indicator lights.
Fig.2.Basic Diagram of PLC As shown in Fig.1, the whole system consists of three different units. The first unit is the PC. The PC runs a program called RS LOGIX 500, which is used to configure the hardware, the software package as shown in Fig.2 and write a control program for the PLC. This control program is downloaded to the PLC through the
automated railway signalling and interlocking system by using a PLC. The use of a PLC can be varied up to the requirements. The PLC is mainly used in industrial purpose, but nowadays it is being used for the accurate control of multiple operations. In the same manner the PLC can be used as a base system or a main controller for the successive

In all PLC systems, the PLC rack or chassis forms the most important module and acts as a backbone to the system. PLCs are available in different shapes and sizes. When more complex control systems are involved, it requires larger PLC racks. Small-sized PLC is equipped with a fixed I/O pin configuration.
Elevator Control System is the system responsible for coordinating all aspects of elevator service such as travel, speed, and accelerating, decelerating, door opening speed and delay, leveling and hall lantern signals. It accepts inputs (e.g. button signals) and produces outputs (elevator cars moving, doors opening, etc.).
