This highly specialized furnace tests the fusibility of coal ash, a critical parameter for boiler design and operation in coal-fired power plants. Operating at very high temperatures (around 1200°C), it observes ash behavior under simulated combustion conditions. The working principle involves heating a cone of compressed ash in a controlled atmosphere while visually or digitally monitoring the temperatures at which it deforms, softens, and flows. Its purpose is purely analytical, predicting slagging and fouling tendencies to optimize boiler efficiency and prevent downtime. It is a key instrument in fuel quality and power generation research labs.

Trutherm manufactures 1400 Degree Celsius (1400°C) Coal Ash Fusion Furnace 315 x 585 x 315 MM Chamber for buyers who search by exact machine type, chamber size and 1400°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 315 x 585 x 315 MM chamber with usable chamber volume of 58 litre, approximate power load of 14.9 kW, rectangular - tall chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
