Patent feed-water heating apparatus, with internal perforated safety tube.
By this invention, the feed-water is forced through a tube or coil placed in the fire-box before it enters the boiler, thereby receiving an amount of heat nearly equal to the temperature of the water in the boiler. The effect of this is to prevent the generation of steam from being checked, as is the case when cold feed-water is injected.
By the use of the internal perforated safety-tube, there is no possibility of the water in the coil assuming the spheroidal condition. Each end of this internal tube is connected with the water space of the boiler, and in the event of any tendency of the water in the coil towards a spheroidal condition, a small jet of water is forced by the pressure of the water in the boiler through the perforation nearest the spot, which at once restores circulation and prevents any risk of injury to the coil.
Three locomotive engines on the London and North- Western Railway have been fitted with this apparatus, with eminently successful results in the rapid generation of steam, and economy of fuel.
In the working of the express engine, No. 248, during the six months ending 30th November, 1861, as compared with the preceding six months, the saving amounted to 27.9 per cent. upon the fuel consumed, the miles run being about 16,500 in both cases. These figures are taken from the official tables of the Company.
By the adoption of the principle involved in this invention, all boilers containing water in tubes are rendered perfectly safe in working.
