Steam and Condensate - A basic overview of a steam system

The boiler house - a basic overview of a steam system -. The boiler is the heart of the steam system. The typical modern packaged boiler is powered by a burner which sends heat into the boiler tubes. The hot gases from the burner pass backwards and forwards up to 3 times through a series of tubes to gain the maximum transfer of heat through the

Steam Pressure Reduction: Opportunities and Issues

domestic hot water, sterilization autoclaves, and air makeup coils. Oversized boiler plants and steam distribution systems utilizing saturated steam are potential candidates for reducing the steam system operating pressure. Steam systems can have large excess capacity in boilers, valves, pumps, and piping.

Steam Powered Water Pump

Water is forced through the tubes by a boiler feed-water pump, entering the OTSG at the "cold" end. The water changes phase along the circuit and exits as superheated steam at the "hot" or bottom of the unit. Gas flow is in the opposite direction to that of the water flow (counter current flow).

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Stratification occurs when, for any reason, velocity is not sufficient to maintain turbulence or thorough mixing of water and steam during passage through the tubes. Stratification most commonly occurs in sloped tubes (Figure 14-7) located away from the radiant heat zone of the boiler, where heat input is low and positive circulation in the

Typically, the exhaust steam is condensed and pumped back into the boiler to increase efficiency. A small pump on the engine pumps the condensed water into the boiler for a closed loop system. Do-It-Yourself Plans for this 2 Cylinder Engine are Available below.
