Study of HP&D exhaust kiln heat conversion and use for drying bricks and tiles

该项目的目标是通过减少天然气和电力消耗，以及在可能的情况下减少整个干燥周期，提高欣顿佩里和达文西有限公司的砖瓦干燥机的能源效率。欣顿佩里和达文希尔有限公司总部设在西米德兰兹郡的达德利，成立于1805年，生产凯特利砖和无畏屋顶瓦。这些都是长寿命产品，已证明使用寿命超过100年。与项目合作伙伴陶瓷干燥系统公司合作，该项目旨在全面研究利用主要热处理热交换器的方案要求，该热处理热交换器将收集各种高温下的所有窑炉废气，并将热量吸收到热油中，将其转移到干燥室，然后通过另一系列热交换器，热交换器将热油中包含的热量释放回干燥器再循环气流中，以在整个干燥循环中使用。这种工艺变化将允许去除气体燃烧器，一次风机和废热供应风机，从而大大降低了我们生产过程中这一关键部分的能耗。我们估计这将减少约900吨二氧化碳排放，（超过我们二氧化碳排放量的10%），并减少我们12%的气体消耗。该项目将详细研究从窑炉废气中转移到干燥机的热量，干燥机在整个循环和产品范围内的基准能耗，以及干燥机内处理通过热量传递的热量的要求交换器.系统容量将与系统设计要求一起进行探讨，以便能够评估这项节能建议的技术、商业和工程方面，并探讨项目的优点和缺点，确定部署热交换解决方案所需的资源，并确认其商业和技术可行性。结果将在一份报告中公布，该报告将被分发如果可行性研究成功，下一步可能是申请第二阶段IETF资金，以支持该解决方案的部署。

The objective of the project is to improve energy efficiency within the Brick and Tile dryers at Hinton Perry & Davenhill Ltd, by reducing gas and electricity consumption, and where possible the overall drying cycles. Hinton Perry & Davenhill Ltd is based in Dudley in the West Midlands and was established in 1805 and manufactures Ketley Bricks and Dreadnought roof tiles. These are long life products with a demonstrated useful life of over 100 years.With the project partners, Ceramic Drying Systems the project aims to fully study the requirements for a scheme to utilise a major thermal processing heat exchanger, that will collect all of the kiln exhaust flue gases at a wide range of high temperatures and absorb the heat into hot oil, transferring it to the drying chambers where it then passes through a further series of heat exchangers, that will release the heat contained within the hot oil back into the dryer recirculation air stream to be used throughout the drying cycle.This process change would allow for the removal of gas burners, primary air fans and waste heat supply fan, thus significantly reducing the energy consumption for this key part of our production process. We estimate that this would save around 900 tonnes of CO2 emissions, (over 10% of our CO2 emissions) and reduce our gas consumption by 12%.The project will study in detail the amount of heat available from the kiln exhausts to be transferred to dryers, the baseline energy consumption in the dryers across the cycles and product range and the requirements within the dryers to handle heat delivered via heat exchangers. The system capacity will be explored together with the requirements of the system design to enable the assessment of the technical, commercial and engineering aspects of this energy saving proposal and to explore the strengths and weaknesses of the project, identifying the resources needed for the deployment of the heat exchange solution and confirm its commercial and technical feasibility.The results will be published in a report which will be disseminated to the bricks and tile industry and made publicly available.If the feasibility study is successful, the likely next steps would be an application for phase 2 IETF funding to support the deployment of the solution.
