Summary:A steam-raising system comprising a boiler (42) . The boiler (42) has (a) a passageway (86) for water and/or steam, (b) an inlet (40) to the passageway (86) through which water is introduced continuously for given periods when the boiler (42) is in use, (c) a heater (88) to heat the passageway (86), and (d) an outlet (44) from the passageway (86) from which steam emerges continuously as water is introduced through the inlet (40) . The system further comprises a pump (14) connected by a flow-path (18, 20, 22, 32, 34, 36, 38) to the said inlet (40) to pump water thereto along the said flow-path (18, 20, 22, 32, 34, 36, 38), and flow-control means (32, 34, 36, 64, 66, 68, 76, 78, 80) in the said flow-path (18, 20, 22, 32, 34, 36, 38). The flow-control means (32, 34, 36, 64, 66, 68, 76, 78, 80) comprise a plurality of lines (32, 34, 36) which constitute a part of the flow-path (18, 20, 22, 32, 34, 36, 38), which are connected between the pump (14) and boiler (42) in parallel with one another, and which are independently openable to enable the amount of water delivered to the boiler (42) to be varied.
