This specialized furnace determines the fusion characteristics of coal or biomass ash at high temperatures, often exceeding 1000°C. It simulates conditions in industrial boilers or gasifiers to predict slagging behavior. The working principle involves heating a molded ash sample in a controlled atmosphere (oxidizing or reducing) while observing the temperatures at which it softens, fuses, and flows. Its purpose is analytical, providing vital data for power plant operators to select fuels and manage boiler operation to avoid damaging slag deposits. It is a key instrument in fuel testing laboratories and energy research facilities.

Trutherm manufactures 1400 Degree Celsius (1400°C) Ash Fusion Furnace 800 x 700 x 700 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 800 x 700 x 700 MM chamber with usable chamber volume of 392 litre, approximate power load of 32.4 kW, rectangular - wide 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.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
