Horne Steam Controls: Sizing Chart - Steam Injection Heater

Download Brochure

The HORNE Steam Injection Heater is made in one size with four pressure ratings. The pressure rating is stamped on the inlet of the heater. If one heater does not pass sufficient steam then two or more heaters should be fitted to a common steam supply.

Example

If a Steam Injection Heater is required to pass 0.052 Kg/sec of steam at a steam inlet pressure of 3.75 bar, the pressure rating can be chosen as follows:

1. Read along horizontally from 3.75 bar on the inlet steam pressure scale.

2. Where the horizontal line intersects with the pressure rating line, read vertically downwards to the steam flow scale.

3. It will be seen that a 5.5 bar rating will pass 0.056 kg/sec of steam and this rating should be chosen for this example.
