 — 1. Introduction. The cement industry is one of the most energy-intensive industries with energy typically accounting about 30–40% of the costs of production [1].According to several studies and the results obtained the production for each ton of cement consumes energy from 4 to 5 GJ/ton.This energy share of the cement industry in …

 — The hot clinkers are discharged from kiln to clinker cooler and hot gases from kiln exhaust are sent to the calciner. In a clinker cooler, a part of energy of solids is recovered back by heat exchange with air. ... refractory and shell were obtained by solving steady state energy balance across the kiln walls. The details of the models and ...

An example using this procedure is shown in Table 9.8 In the preceding pages tile chemistry of the kiln feed and clinker have been extensively discussed. The novice reader should now have a fairly broad knowledge of the many problems and factors that are associated with making cement clinker in a kiln.

The thermal efficiency of rotary kiln clinker coolers of all types of design is within the range of 40 to more than 80%. b)Another criterion for judging the cooler efficiency is the temperature difference between the hot clinker entering the cooler and the hot secondary air leaving the Furthermore, the best cooler is the particular cooler which, because of its …

 — The mass balance was examined for clinker production and across the boundary of the kiln system, which included the pyro-processing (unit 3), kiln (unit 4), and cooler (unit 6) units, but did not include the coal mill (unit 5) (Fig. 8). The streams entering the system are raw meal, air into the kiln and cooler, and coal fired into the kiln and ...

 — A large amount of thermal energy is required to create enough heat for the cement kiln and precalciner. Typical thermal energy consumption of clinker manufacturing with different kiln process is illustrated in Table 6 . The reference plant has the configuration of a five-stage preheater tower with two rotary kilns.

 — Once the clinker is formed in the rotary kiln, the melted material must be cooled rapidly to maintain product quality. After getting cooled, the clinker now can be safely handled to be stocked in clinker silos. ... Uday G (2002) Energy balance and cogeneration of cement plant. Appl Therm Eng 22:485–494.

Clinker: reactions in the kiln. The milled and blended raw materials go to a silo and then to the kiln. Reactions which take place as the feed passes through the kiln are reviewed below. They can be considered under three broad headings: Decomposition of raw materials - temperatures up to about 1300 °C.

Illustrated screen from the Dynamis software of mass and energy balance for clinker kiln line.

 — Material and energy balance is performed using a Microsoft Excel sheet. The thermal energy requirement from petcoke combustion and its sensible heat is 1.938 and 0.002 MJ/kg clinker for calcination. All input data is fed to Aspen Plus simulation software.

In case of an emergency, such as badly overheated cooler conditions, the kiln operator has two more possibilities to bring the cooler under control: the amount of clinker falling into the cooler can be decreased by slowing tl1e kiln speed, or the temperature of the clinker falling into the cooler can be lowered by adjusting the flame geometry ...

 — The cement industry is undeniably critical for the global economy. However, they are also the largest energy consumers in the world.
