Abstract

In a system for setting in operation boilers with forced flow, a reduction of the minimum flow to 15% of full load takes place during setting in operation by the use of an internally ribbed tube arrangement which has a large number of pipes and leads to the installation tubes in the admission zones which have a high heat. Working also takes place with an adjustable pressure bypass stop valve in the main flow path. Also provided are a pressure-reducing device in the bypass system and two steam-jet temperature regulators from a condensate collector or from separators. The first steam temperature regulation takes place on the outlet side of a secondary superheater and the second steam temperature regulation takes place on the outlet side of a reheating device.
