Oxygen combustion in cement production

Utilization of Coal Combustion By-Products and Green Materials for Production of Hydraulic Cement

Quantitative Measurement of Oxygen in Microgravity Combustion

A low-gravity environment, in space or in ground-based facilities such as drop towers, provides a unique setting for studying combustion mechanisms. Understanding the physical phenomena controlling the ignition and spread of flames in microgravity has importance for space safety as well as for better characterization of dynamical and chemical combustion processes which are normally masked by bu...

Sulfur Release from Cement Raw Materials during Solid Fuel Combustion

During combustion of solid fuels in the material inlet end of cement rotary kilns, local reducing conditions can occur and cause decomposition of sulfates from cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, which may cause deposit formation in the kiln system. SO2 release from cement raw materials during combustion of solid f...

Oxygen-flask combustion with light beam ignition.

A robust oxygen-flask combustion system was developed using light beam ignition. An appropriate amount of environmental sample was wrapped with a small piece of filter paper and held in a basket made of platinum-zirconium spiral. After the sample was inserted into an oxygen-filled flask containing an acid mixture, the light beam from an overhead projector lamp was focused to ignite the sample. ...

Environmental Impacts of Cement Production

Будівельна промисловість є одним з лідерів щодо забруднення довкілля внаслідок вичерпування ресурсів і затрат енергії або утворення відходів. Крім того, спостерігається значна емісія від парників, кислотних газів від будівельної промисловості. Цемент належить до одного із найвикористовуваніших будівельних матеріалів у світі, а його виробництво невпинно зростає. А цементна індустрія є дуже енерг...
