Otto-Hoffman's by product oven

Subject and UNIT: Engineering Chemistry: Unit IV: a. Fuels Engineering Chemistry

There are so many types of ovens used for the manufacture of metallurgical coke. But the important one is Otto-Hoffman's by product oven.

Requisites, Characteristics

Subject and UNIT: Engineering Chemistry: Unit IV: a. Fuels Engineering Chemistry

When bituminous coal is heated strongly in the absence of air, the volatile matter escapes out and the mass becomes hard, strong, porous and coherent which is called Metallurgical Coke.

Definition, Types

Subject and UNIT: Engineering Chemistry: Unit IV: a. Fuels Engineering Chemistry

When coal is heated strongly in the absence of air (called destructive distillation) it is converted into lustrous, dense, porous and coherent mass known as coke. This process of converting coal into coke is known as Carbonisation.

Subject and UNIT: Engineering Chemistry: Unit IV: a. Fuels Engineering Chemistry

In order to assess the quality of coal the following two types of analysis are made.

Subject and UNIT: Engineering Chemistry: Unit IV: a. Fuels Engineering Chemistry

Coal is an important primary solid fuel, that has been formed as a result of alteration of vegetable matter under some favourable conditions.

Subject and UNIT: Engineering Chemistry: Unit IV: a. Fuels Engineering Chemistry

Fuels are classified based on occurance and physical state as follows.

Subject and UNIT: Engineering Chemistry: Unit IV: a. Fuels Engineering Chemistry

A fuel is a combustible substance, containing carbon as the main constituent, which on burning gives large amount of heat.

They possess lower electrical conductivity and thermal expansion.

Introduction, Definition

Subject and UNIT: Engineering Chemistry: Unit III: b. Composites Engineering Chemistry

A composite material may be defined as, "a material system consisting a mixture of two (or) more micro-constituents, which are mutually insoluble, differing in form (or) composition and forming distinct phases".
