“…Optimization of the most suitable product form and firing temperature, together with heavy clay raw materials chemical composition, trapezoidal membership function is used [14,15]. Also, mathematical methods are performed in order to optimize fuel/air use in tunnel kiln in production of bricks with addition of low calorific value coal [16]. Since the literature on mathematical optimization of production and waste additions in brick industry is very limited, further research and development is necessary [17].…”

“…Many kilns also use a mixture of fuels. Although, some authors describe coal as the traditional fuel in brick firing [84,85]. In other cases, fuels are added separately and in others, they are pre-mixed.…”

A large part of the global brick manufacturing industry has evolved based on knowledge transmitted from generation to generation without developing a consistent scientific approach. The purpose of this article is to contribute to this approach by discussing the state-of-the-art and future trends of the design and construction of artisan brick kilns (ABK). The methodology proposed for this study is based on a systematic literature review whereby main question is: What research exists on brick kilns? Based on the results of this review, it is recommended that appropriate emerging technologies that should be incorporated to ABKs for either medium or small enterprises should be: mechanical fans, envelope thermal insulation, organic waste of uniform size as fuel, automatic control of process variables and computer simulations of phenomenological processes. This should be accompanied by technical training for the brick-makers and greater access to financing funds. The technologies reviewed throughout the paper will allow for a more thermally efficient design of kilns, which will emit less hazardous greenhouse gases and atmospheric pollutants.

Carrying out experiments in tunnel kilns are difficult and costly. Due to the large length of such kilns that sometimes reaches 180 meters. That causes the production cycle takes some days. Therefore, a mathematical model is needed to simulate the heat transfer process in such kilns. In this contribution, a simple shape product (vitrified clay pipes) was used in the modeling, in order to simplify the complexity of the process. The bvp4c code was used to solve all ordinary differential equations (ODEs) of the model to obtain temperature profiles of the system using Matlab. Results revealed that: the excess air number has a higher impact on the heat transfer process inside the kiln. Consequently, the thermal heating of products could be easily controlled, by changing the excess air values. Heat transfer coefficient enhancement is a key parameter to save the energy consumption within the kiln.
