Types of Kilns | HowStuffWorks

The three most common types of kilns are electric, gas and wood. Electric kilns are probably the most common type of kiln used in ceramics. They're comparatively inexpensive, and small ones can plug directly into a 120-Volt wall socket, making them accessible to small pottery operations.

11.6 Portland Cement Manufacturing - US EPA

Preheater and precalciner kiln systems often have an alkali bypass system between the feed end of the rotary kiln and the preheater tower to remove the undesirable volatile constituents. Otherwise, the volatile constituents condense in the preheater tower and subsequently recirculate to the kiln.

Addition of Pre-Calcination to Kilns with Preheaters ...

An existing preheater kiln may be converted to a multi-stage preheater/precalciner kiln by adding a precalciner and, when possible an extra preheater stage. The addition of a precalciner will generally increase the capacity of the plant, while lowering the specific fuel consumption and reducing thermal NOx emissions (due to lower combustion temperatures in the precalciner).

Preheater - an overview | ScienceDirect Topics

Short dry kilns are usually accompanied by an external preheater or precalciner (Figure 1.7) in which the feed is dried, preheated, or even partially calcined prior to entering the main reactor (kiln). As a result the thermal load on the kiln proper is reduced.

Cement Kilns: Suspension preheater kilns

Such heat as escapes the preheater is used to heat the rawmill. The concept of the suspension preheater gradually emerged when, from the 1920s onward, some kilns started to be fitted with cyclones to remove most of the dust from kiln exhausts, and to return it to the kiln.

Lime kiln - Wikipedia

Types of kiln. Permanent lime kilns fall into two broad categories: "flare kilns" also known as "intermittent" or "periodic" kilns; and "draw kilns" also known as "perpetual" or "running" kilns. In a flare kiln, a bottom layer of coal was built up and the kiln above filled solely with chalk.

From the preheater, the raw meal enters the kiln at the upper end. It slides and tumbles down the kiln through progressively hotter zones toward the flame. At the lower end of the kiln, fuels such as ground coal, petcoke and natural gas feed a flame that reaches 3400 degrees Fahrenheit—one third of the temperature of the sun's surface.
