5.4.1 Hydraulic diagram
The basic diagram most commonly used in practice for the connection of gasification
boilers is given below. Using the diagram below, systems with direct heating circuits and
without the use of additional house controllers operate normally, although significant time
variations in the processes may occur (e.g.: duration of storage tank filling, riser temperature
fluctuations, etc.). The pump to be used for installation shall be a pump with designation 25-
60-180 or a pump of equal or greater capacity.
