The application of the 'from and at' rating graph (Figure 3.5.1) is shown in Example 3.5.1, as well as a demonstration of how the values are determined. Example 3.5.1. A boiler has a 'from and at' rating of 2 000 kg/h and operates at 15 bar g. The feedwater temperature is 68°C. The use of Equation 3.5.1 will determine a factor to

Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

The company adopts the same standard of German enterprises to demand the quality of the boiler quality strictly. It has one-step service including R&D, design, manufacture, installation, commissioning, pre-sale, on-sale and after

Read MoreThese boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.
