What is electric muffle furnace?
A Muffle furnace allows rapid high-temperature heating, recovery, and cooling in self-contained, energy-efficient cabinets. A muffle furnace separates the object to be heated from all byproducts of combustion from the heat source.
What is the principle of furnace?
Whatever fuel a furnace uses, it operates on the principle of forced air heating. The furnace transfers heat to air, which blower fans then send through the ductwork of a house and out vents.
What is muffle furnace in pharmacognosy?
Muffle Furnace is an extremely heated chamber, walls of which can radiantly heat the content which is kept inside so that material cannot have direct contact with the flame. These furnaces are often utilized in the testing laboratories as a means to create extremely high-temperature inside the chamber.
What is the range of muffle furnace?
Standard models of our muffle furnaces come with maximum temperature range 1200°C, 1400°C, 1700°C and 1800°C.
What is the difference between muffle furnace and oven?
A hot air oven is made up of stainless steel chamber and outer body is made up of mild steel. It works on the temperature range from 50° to 250°. A muffle furnace is a clay oven because it works on very high temperature. Had it been made up of metal, it would have been melting at such a high temperature.
What are the types of muffle furnace?
Several types of muffle furnace
- Box-type furnace. As the name suggests, the box-type high-temperature furnace is the same as a box, which is the traditional muffle furnace, but with stronger functions and better thermal insulation performance.
- The tube furnace.
- Atmosphere furnace.
- Well type furnace.
What are the three types of furnaces?
What Are the Different Types of Furnaces?
- Gas Furnace.
- Oil Furnace.
- Electric Furnace.
- Modulating Furnace.
What is the principle of annealing?
Annealing is a heat treatment procedure involving heating the alloy and holding it at a certain temperature (annealing temperature), followed by controlled cooling. Annealing results in relief of internal stresses, softening, chemical homogenizing and transformation of the grain structure into more stable state.
Where is muffle furnace used?
Muffle furnace is widely used in test laboratories with a compact means to create a high-temperature say up to 1200 degree Celsius to test the characteristics of the material for highly accurate test results. Muffle furnace is an oven type instrument which can reach high temperatures.
What are the advantages of muffle furnace?
The Yatherm Scientific muffle furnace offers numerous advantages, such as; low proportional energy consumption, more efficient thermal insulation, more uniform heat distribution in the equipment, temperature and process control, high performance and durability heating system, exhaust gases from the process, robust …
How does a muffle furnace work?
With modern electrical furnaces, this means heat is applied to a chamber through induction or convection by a high-temperature heating coil inside an insulated material. The insulating material effectively acts as a muffle, preventing heat from escaping.
What is the function of an oven?
Ovens are used as kitchen appliances for roasting and heating. Foods normally cooked in this manner include meat, casseroles and baked goods such as bread, cake and other desserts. In modern times, the oven is used to cook and heat food in many households across the globe.
How does a muffle furnace in an oven work?
2. 2 WORKING OF MUFFLE FURNACE A muffle furnace isapiece of oven-type equipment that can reach high temperatures. It usually works by putting a high-temperature heating coil in an insulated material. The insulating material effectively acts as a muffle, preventing heat from escaping.
What is the maximum temperature of a muffle furnace?
High temperature muffle-furnace, maximum temperature is 1,473 K (1,200 °C; 2,192 °F). A muffle furnace or muffle oven (sometimes retort furnace in historical usage) is a furnace in which the subject material is isolated from the fuel and all of the products of combustion, including gases and flying ash.
What is the working principle of a furnace?
The working principle is based on the law of conservation of energy. That is, from electric energy to heat energy. When the electric furnace works normally, voltage and current are applied to the heating element (resistance).
