Burner combustion system. The Metso kiln burner is designed for maximum flexibility of fuel type and flame shape. The primary fuel is typically pulverized coal or coal+coke, with the option to burn natural gas or fuel oil. Either natural gas or fuel oil can be ignited directly by the integral ignition system.

Kiln burner is industrial burner used in kiln industry area. Always it adopts detached type, that is, its air supply system and combustion system is separated. Our kiln burner can be used for different fuels as flammable gas, flammable oil, flammable liquid and pulverized coal etc.
Carbon Rotary Kiln Burner 1.The primary air wraps the fuel, and the rotary kiln burner minimizes the contact area between fuel and hot air, effectively reducing NOx emission; 2.The burner has a flame stabilizer in the center, which can run stably even under low load; Read More
A rotary kiln (16) fired with pulverized coal as the primary fuel with the firing system including a burner (22) capable of utilizing coal, gas or oil. The firing system and burner are such as to provide particular ratio of burner discharge area to primary air flow for coal firing so as not to contaminate the kiln product during coal firing operation.
A central burner located at the kiln discharge end is used with LDO (light diesel oil) for heating the cold kiln. After initial heating, the fuel supply is turned off and the burner is used to inject air for coal combustion. The kiln temperatures are measured with fixed thermocouples and ‘quick response thermocouples’ (QRT) ports.
Disclosed is a method for firing a kiln as well as a method for producing cement clinker in which pulverized coal is initially entrained in an airflow of about 2% of the theoretical amount of air needed to combust the coal and transport it to a burner. Supplemental primary air heated sufficiently to vaporize volatiles in the coal is mixed with the coal flow in a burner, discharged into the

Petcoke-Coal-Biomass Burners Micronized petcoke / coal / biomass Kiln Burner (without hammer mill) The SFD group for solid fuels is a simple and rational system, both for Hoffmann and Tunnel kilns, born from the increasing need for saving in conduction of the kiln and combustion efficiency.
kiln. Mathematic models of coal combustion have made better progresses in other fields. However, modeling of coal combus-tion for a cement rotary kiln was mostly carried out in the burning zone close to the burner and did not account for the * Corresponding author.

Advantages. Features different from other equipment:. 1. Customized coal powder preparation system consists of: coal powder screening, coal powder mill and powder discharging system; the finess of coal powder outlet which reaches to 80 meshes accounts for over 90%, which completely solve problems such as complex structure, large covering area, lots of wear parts, uneasily management and
In the early 1990s, Greco constructed rotary kiln burners for the local cement manufacturing industry and was among the first suppliers to provide the burners needed for changing over the numerous heavy oil and coal firing systems to the cheaper petcoke fuel. From today’s viewpoint the company’s petcoke burner design was advanced technology.
Singhania System Technologists Pvt. Ltd. has installed over 150 Swirl Flame Rotary Kiln Burners in India & abroad. The largest capacity of the Rotary Kiln Burner manufactured so far is 147 MKCal/hr. on a 11,000 TPD Rotary Kiln which used lignite as a fuel for a Cement Plant.
Mar 30, 2013· Flame burning at the burner tip or sometimes coal drops 1.Too low coal injection velocity . This may be due to rotor gap fo blowe has increased or blower filter got choked. If coal pipe got punctured inside the burner coal will mix with primary air flow and damage further. check for wear of the coal injection pipe tip.
Pulverized coal volatiles: pulverized coal with low volatiles (< 15%) tends to form rotary kiln burner flames with long black heads, short high temperature parts and high local flame temperatures. Although the coal powder with high volatiles (> 30%) is quick to ignite, it takes a certain time for volatiles fractionation and combustion, and the
