PTPR gas melting stationary furnace with recuperation system up to 1200 °C

Recuperation to minimise your gas consumption

This furnace is used for melting metals up to 1,200 °C (approx. 1,100 °C in the crucible) and, if needed, the subsequent pouring of the melted product over into a transport ladle or a transport holding furnace. It is then transported for further processing. The furnace is fitted with a recuperator which preheats the air intended for combustion in the gas burner. Through this it reduces chimney losses and thus the furnace’s consumption. This in turn can give you gas savings of 25 to 30% compared to an ordinary gas furnace.

A melting gas stationary furnace PTPR with a recuperation system save 25–30 % of gas when compared with standard gas furnaces

We have furnished our gas burner with a recuperator, which preheats air intended for use at combustion. Using this method, chimney losses are reduced which results also in furnace’s power consumption reduction. Furnace has minimal heat losses due to the use of topquality insulation materials and a rotary lid - a compact octagonal configuration of the furnace designed to reduce the dimensions of the unit and heated furnace chamber.

As an example, we present the PTSPR 1000/09 furnace consumption measurement when melting 1,000 kg of aluminium when compared with a standard available melting gas furnace:
