Jun 27, 2014 · Boiler Process Instrumentation and controls. In a complex steam distribution system there will be several components. These will include heat exchangers, process equipment, flash tanks, and storage tanks. Heat exchangers are the places in the system where steam is used to heat a process or air by indirect contact.
P&ID is defined as a diagram of piping and instrumentation and it shows the process flow in pipes, as well as, the equipment installed and instrumentation. Another possible name used for a P&ID is PFD which is a simplified form (Process flow diagram), although this is a less used.

A piping and instrumentation diagram (P&ID) is a detailed diagram in the process industry which shows the piping and process equipment together with the instrumentation and control devices. Superordinate to the piping and instrumentation diagram is the process flow diagram (PFD) which indicates the more general flow of plant processes and the relationship between major equipment of a plant facility.
symbols exist in the various norms they are only particularly suited to the relevant area of application of the norm (e.g. norm for fire safety installations DIN 19 227 part 2, norm for thermal electric stations DIN 2481 and EN ISO 10 628 flow chart for process plant). In some cases different icons are used for one and the same valve type and actuator.
