Steam kettles range in capacity from 2 gallons (7.5 L) to over 100 gallons (378.5 L). Some large institutional kettles hold 4,000 gallons (15,142 L). Tilt or trunnion kettles can be tilted for emptying, either by turning a wheel or by pulling a lever. Nontilt kettles are emptied by a spigot and drain on the bottom. Heat is controlled by regulating the steam flow or by adjusting the thermostat. Steam may be from an outside source or self-generated. Exercise caution when operating all steam equipment. Steam can cause serious burns.
