0519 - R304P - Westinghouse Technology 7.3 Westinghouse

The gland steam system (Figure 7.3-3) has two sources of steam supply: the auxiliary boiler and the main steam system. In the initial phases of a startup from cold shutdown, gland steam is supplied from the auxiliary boiler. Once the plant is heated up, the gland steam requirements are supplied by the main steam …

difference between boiler and steam generator - Steam Boiler

Kefid · Difference between CFB boiler and pulverised coal boiler For CFB boilers,the combustion of coal takes place at a relatively lower temperature of around 850-900 deg C, necessitating lower thermal insulation of the boiler compared to Pulverised Coal boiler. Steam is generated, driving a steam generator and turbine.

STEAM DRUM WATER LEVEL MEASUREMENT

Well, there is a difference between the steam generator and the steam boiler although the purpose of both types of equipment is the same, that is to generate steam. When water is turned into steam by boiling at sub-critical pressures, the equipment is then called a steam boiler.

On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a large amount of steam on unit gas mass basis. Table 1 shows the gas/steam ratio of HRSGs and steam generators. The small ratio of steam to gas flow in a HRSG is not adequate to cool the

Boiler codes define a significance of applications. A boiler is a pressure-holding container producing steam at a pressure of generally 2 bar and higher. There is, however, no universal definition. Boilers are also called steam generators. Boilers of the early eighteenth century were no more than large kettles.

Why Steam Generators Are Better Than Steam Boilers

Jun 02, 2020 · Steam generators are ideal for on-demand situations. They are smaller and easier to start up compared to steam boilers and, thus, may be used as auxiliary boilers. Generators usually do not have the same maximum capacity as fuel fired boilers, so they are best for applications that require point of use dry steam.

Pressurized Steam - an overview | ScienceDirect Topics

Steam can be produced by burning fossil fuels such as natural gas, and releasing their chemical energy to heat the high-pressure liquid in the boiler tubes (water wall tubes, risers, down-comers, superheaters, and economizers). Steam can also be produced by a heat recovery steam generator (HRSG) placed, for example, at the exhaust of a gas turbine.
