# Burning factor means in cement kiln

state of kiln operation, the ratio is 2.3. This defines a burning index and is a mea-sure for how the kiln in that state of oper-ation on average burns the kiln feed. Reasons for variations in burnability could be insufficient raw mix control and/or homogenisation of the kiln

• Optimization of Burner Kiln 7, Cementa Slite

Kiln: Big oven for making of cement. LSF: Lime saturation factor. A higher LSF means higher specific energy consumption, the material becomes harder to burn. Clinker: The product is taken out of the kiln and is later on ground to cement. Clinker factor: This is a fraction of what is put into the cyclone system as raw meal and taken out as clinker

However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the

• Cement Kilns: Design features of rotary kilns

The early commercially successful rotary kilns in Britain were nearly all straight cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were

• Reducing the Clinker Factor – Part 1 | World Cement

Sep 04, 2015 The incentive to ‘reduce the clinker factor’ in cement products is two-fold. The primary motivation is to reduce the energy consumption and CO 2 emissions associated with cement clinker production in rotary kilns. It is generally accepted that the production of 1 t of ordinary Portland cement (OPC) creates over 800 kg of CO 2. The secondary reason is to reduce the environmental impact of

As applicable to cement kilns, low-NOx burners means a type of cement kiln burner system designed to minimize NOx formation by controlling flame turbulence, delaying fuel/air mixing, and establishing fuel-rich zones for initial combusting, that for firing of solid fuel in the burning end zone of a kiln's main burner includes an

Combinability of raw materials used to make Portland cement. Clinker: combinability of mixes. The ease of combination ( combinability , or burnability ) is about how easily the raw materials react with each other in the kiln to produce the clinker minerals

• Cement Kilns: Precalciner kilns

They represent the final improvement in efficiency, and hold out the prospect for nearly total elimination of heat wastage from cement kilns. The precalciner system is a suspension preheater in which, in addition to the kiln flame, extra fuel is burned in the base of the preheater. The first kilns of this kind operated in Japan in the late 1960s

About 53 million tires per year are consumed as fuel in US cement kilns. The cement industry burns scrap tires as fuel in kilns used to make clinker—a primary component of portland cement.
