USUAL POSITION TO HOT SPOT Main Text: The next curves give the rate of heating with the superheat system; the standard exhaust curve being inserted for comparison. The heating rate is increased by employing the small (.025) dia. feed hole but even then approx. 2 1/2 mins. elapse before there is any appreciable rise in temperature whereas the standard system responds immediately. After about 4 1/2 mins. running, the temperature reached is the same as that of the exhaust heated system after the same time, but it soon assumes a constant value of 95°C, while the other still contd :- Graph Text: SUPERHEAT SYSTEM.
