Plant Design Part 3: Heat Transfer Part 2

Cooling Tower
Cooling Tower Analysis is a powerful, user friendly, program for the analysis of induced, mechanical-draft, counterflow cooling towers. The program can be used for the analysis of existing towers or for the preparation of specifications for new towers.
Steam Heater
This program calculates the performance of a steam, shell-and-tube heat exchanger of known construction using rigorous formulations. Steam and water properties are built in. The type of fouling can be specified. The shell-side fluid is always steam. The tube side fluid can be any non-condensing fluid.
Heat Recovery Steam Generator
This program calculates the amount of steam that can be generated by a fired or unfired waste heat boiler (Heat Recovery Steam Generator). The steam and condensate properties are built in. The program first calculates a design mode and then an "off-performance mode" for changed conditions.
Insulation Economics
This program calculates the heat loss and surface temperature of an insulated pipe of specified diameter and internal temperature. It then calculates the present worth cost, $/foot, to own and operate each insulated system. This allows the user to select the optimum insulation thickness for each pipe based either on the cost of the insulation and heat loss or on the maximum acceptable surface temperature. Four types of insulation are supported. Pipe sizes through 36" are included. Three layers of insulation are supported ranging in thickness from 0 to 10".
Shell & Tube Heat Exchanger
Heat Exchanger Performance is a powerful, user friendly, program for the analysis of two types of Heat Exchangers: Shell & Multi-Tube Exchangers, and Double Pipe Exchangers. In either case, the tubes are of the bare-tube type. The program will analyze the performance of a known heat exchanger: Given the flows and inlet temperatures of the Tube-side fluid and the Shell-side fluid, the program will predict the exit temperatures of both fluids and the total heat exchanged.
