HOTBLAST Meaning and
Definition
-
Hotblast is a term that refers to a heating method utilized in metallurgy, specifically in iron smelting or in the production of steel. It involves the process of preheating air before it is blown into a furnace, resulting in increased combustion efficiency and extremely high temperatures.
In the hotblast process, a blower is used to force air through a furnace, where it undergoes various stages of heating before reaching the combustion zone. The air is typically passed through a series of pipes or ducts, which are heated by the waste gases or other heat sources generated by the furnace. This preheating significantly raises the temperature of the incoming air, thus improving the overall energy efficiency of the system.
The purpose of hotblast is to increase the available heat and ultimately enhance the productivity of the furnace. With the utilization of preheated air, combustion within the furnace is facilitated at a faster and more intense rate, allowing for higher temperatures necessary for the smelting or production of iron or steel. The hot air also increases the effectiveness of fuel combustion, reducing the fuel consumption required for the process.
The innovation of hotblast technology played a crucial role in the advancement of the iron and steel industry during the industrial revolution. It drastically improved production rates, reduced costs, and permitted the operation of larger, more productive furnaces. Consequently, this approach transformed the industry, making iron and steel production more economical and contributing to the development of modern infrastructure and industrialized societies.

Etymology of HOTBLAST
The term "hotblast" originated in the field of metallurgy and specifically refers to a technique used in iron production. The etymology of the word can be understood by breaking it down into its two components: "hot" and "blast".
The word "hot" is derived from the Old English word "hat", which means heat or burning. It has cognates in other Germanic languages such as German "heiß" and Dutch "heet", all of which ultimately trace back to the Proto-Germanic word "haita".
The term "blast" has its roots in the Old English word "blǣst", which means a strong gust of air or wind. This word shares its origins with the Old High German word "blist", the Old Norse word "bles", and the Gothic word "blesan", all of which connote blowing or blasting.
