Modern Brick Kilns Yield Development Benefits in Bangladesh
However, HHK technology costs up to 15 times more to build than traditional kilns. Carbon finance tools and mechanisms played a catalytic role to create incentives for the first entrepreneurs to adopt cleaner brick technology and provide additional comfort to financial institutions willing to loan money at a rate applicable to prime customers.

Decarbonising the lime industry: State-of-the-art
The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes of CO 2 arising …

Modernizing Artisanal Brick Kilns: A Global Need
Bickel says EELA's long-term goal is to reduce kiln emissions by 30–50%. But achieving that goal won't be easy. Throughout Latin America and other countries in the developing world, artisanal kiln operators comprise an informal industry; they rarely pay taxes or obtain operating permits, and because of that, they often lack access to the …

under gravity. Parallel evolution of shaft kiln technology with the more complex dry process rotary kilns kept the mix of pyroprocessing technologies in China's cement industry more diverse than in almost any other country. Coal is the primary fuel burned in cement kilns, but petroleum coke, natural gas, and oil are also consumed.

An Introduction to Fuel-Burning Kilns
Now most fuel-burning kilns are fueled with a liquid such as oil, or a gaseous fuel such as natural gas or propane. Fuel-burning kilns may be very simple structures; sawdust kilns fall in this category. More sophisticated fuel-burning kilns are designed around a concept of heat flow and they can be categorized in this way.
