Heating Water With Steam Nozzles. A nozzle for heating water, noiselessly, by meansof steam in direct contact, is shown in perspectivein Fig. 24. It consists simply of an outward andupward discharging steam nozzle, covered with ashield which has nimierous openings for the ad-mission of water so that the jet takes the form ofan inverted cone, discharging upwards. To makethe operation of the apparatus noiseless, air is ad-mitted through a small pipe and drawn in by thejet. By mixing with the steam this air prevents thesudden collapse of bubbles, and the consequent Quieting the Noise 117 noise which is such a great objection to heating bydirect steam in the old way. A valve or stop cockshould be placed on the air pipe so the supply ofair can be regulated to the quantity most water is to be heated to a less tempera-ture than 165 degrees Fahrenheit and that tem-perature is sufficient for all domestic purposes, the.

If however, the tem-perature of the water must be raised above 165degrees Fahrenheit, the air pipe should be the pressure of steam is sufficient, air neednot be delivered to the nozzle under however, the steam pressure is low the airmust also be delivered under pressure to insure thenoiseless operation of the apparatus.
