Application filed February 14, 1925. Serial No. 9,267, and in Germany February 16, 1924.
My inventionrelates toimprovements in steam generating plants of that. type in which a regulatingor control device for compensating or equalizing the fluctuations in- 6' the steam consumption is provided. The equalization is brought about by means of a feed water storage vessel while the firing of the steam generator is continued uniformly.
During period'sof low steam consumption the surplus steam, which may for instance be withdrawn from a suitable stage of a turbine, is conductedthrough a heater in which it heats the feed water. The hot feed water is conducted intoa feed water storage vessel from which it is conducted into the boiler during periods of increased steam consumpcontrol device which compensates or equal-.
izes great fluctuations in the steam consumption by the aid of a relatively small feed water storage vessel. For this purpose regulating means are provided which reduce the further steam generation and relieve the storage vessel to the extent of its-state of charge. The reduction of the steam generation may-take place in such a way, for instance, that'the quantity of the fuel introduced into the furnace of the boiler is diminished. The relief of the storage vessel may be eflected by conducting the surplus any stage of a power engine fed by said boiler not into the feed heater but to other consumers.
An embodiment of my invention is dial5 gram-amtically represented in the drawing aflixed to my spectiflcation and forming part thereof. I
Referring to the illustrated'example is a steam boiler which feeds the high-pressure turbine 31 and the low-pressure turbine 32) 33 is a condenser and 44 and 45 representother steam consumers. The cold feed water 46 is conveyed into the feed water storage vessel 54 by the pump 47, through the steam steam developed from the boiler or from.
The float 55 acts through an extension of .the same mechanism 56 simultaneously upon the boiler furnace, by slightly closing the fuel supply valve 58 iii a liquid fuel furnace,
forinstance, as indicated in the dra'wingand thus reducing the supply of heat. It will be understood that this particular arrangement is by no means essential and that myn invention extends to any suitable means for limiting the supply of fuel to a boiler during periods of low steam demand in dependenlce upon the state of the feed storage vesse v If now storage vessel 54 as dropped down to near the bottom of said vessel, the valve 57 is closed again by thefloat 55 in ac-[ cordance with the low 'level of thewater, more steam again enters the steam' heater 48 an'd'the pump 47 supplies more water so that the storage vessel 54 is filled up again with water. Simultaneously the valve 58 controllin'gthe supply of fuel to the boiler furnace is opened again fully so that the supply of heat to the boiler and thus the generation of steam is increased again.
It will be understood that the mechanism illustrated and the other modifications men tioned are examples only and that my -inv the level of the water in the feed 5 steam consumers supplied with steam from any suitable stage of said power engine, the
said heater into said feed water storage Vessel, a regulating device adapted to control the quantity of the cold feed water supplied in accordance with the temperature of the heat-- ed feed water, a measuring device adapted a to supervise the state-of charge of said storage vessel and a mechanism responsive to the state ot charge of the storage vessel for controlling the fuel supply to the steam generator to vary the steam generation and for directing surplus steam to other consumers.
2. In a steam power plant consisting of a steam generator,
consumers supplied with steam from any sultable stage of said power engine, the coma'power engine supphed by said steani generator and a plurality of steam bination of a feed water. storage vessel, a steam heater for said feed water supphed with surplus steam from said power engine,
a pump for forcing cool feed water through said heater into said feed water storage vessel, a regulating device adapted to control the quantity of the cold feed water supplied in accordance with the temperature of the heated feed water, a float device in the feed storage vessel, a valve connected wit-h the steam conduits associated with said power engine and adapted to control the steam supply to a consumer, gearing adapted to transm1t the motion of said float to said valve, a control device adapted to regulate the supply of fuel .to the steam generator and a linkwork also geared to said float and adapted to transmit the motion of said float to said fuel control device.
In testimony whereof I afiix' my signature.
