The development of the Heye melter had its origin in the Unit Melter produced in the USA during the 1950s, when the primary energy costs were relatively low. It used a high energy fuel without air preheating. As the cost of construction was much lower than for a regenerative furnace, capital was sdh available to invest in forming machines. Because electricity was at that time relatively expensive in Europe Heye decided to install a waste heat boiler on the melter and use the steam produced to operate steam turbines. As energy prices increased the furnace system was developed further, the primary energy requirement being decreased by installation of recuperators, subsequent development led to the introduction of the Obernkirchen Furnace C. This furnace is fitted with recuperators which preheat combustion air to 800 °C and the gas fuel to 500 °C. The waste heat boiler has a maximum output of 9 t/h at 30 bar and 450 °C. With dimensions of (8,4 x 20) m- and a glass depth of 1,4 m the furnace can melt about 340 t glass/day. The specific heat consumption is thus less than 5040 kJ/kg glass (1200 kcal/kg glass, > 1,39 kWh/kg glass) without allowance for steam production.
