The Southern Alberta Institute of Technology (SAIT) and Canada's Oil Sands Innovation Alliance (COSIA) are collaborating to innovate pilot lab-scale once-through steam generators (OTSGs) through a novel design and construction configuration of part of the process. This new design is required to improve steam quality, increase energy efficiency and reduce environmental impacts. OTSGs convert boiler feed water (BFW) of poor quality, non-potable water to high-quality steam required for in-situ resource recovery. The elevated concentrations of dissolved organic and inorganic impurities and residual organo-metallic species present in the BFW cause scaling and fouling. This causes corrosion and erosion in the OTSG tubes, leading to their premature failure. The objective of this new applied research project is to assist the development, construction, operation and testing of a novel hybridized prototype metal test coupon and heater on the pilot test rigs at SAIT. This new research project will focus on two novel and important inclusions through the design and construction of: (i) metal test coupons and (ii) a heater with superior heat exchange capacity to hybridize the pilot skids and simulate the field OTSG conditions for erosion and corrosion. This innovation will entail a systematic investigation to determine the composition and the effect of scale and fouling in retarding heat transfer and the erosion and corrosion mechanisms that foster their residence on the surface of the metals under the deposits.

南阿尔伯塔理工学院 (SAIT) 和加拿大油砂创新联盟 (COSIA) 正在合作，通过部分流程的新颖设计和施工配置来创新试点实验室规模的直流蒸汽发生器 (OTSG)。这种新设计需要改善蒸汽质量、提高能源效率并减少对环境的影响。 OTSG 将劣质非饮用水锅炉给水 (BFW) 转化为原位资源回收所需的高质量蒸汽。 BFW 中溶解的有机和无机杂质以及残留有机金属物质的浓度升高会导致结垢和结垢。这会导致 OTSG 管腐蚀和侵蚀，导致其过早失效。 这个新的应用研究项目的目标是协助 SAIT 中试试验台上新型混合原型金属试件和加热器的开发、建造、操作和测试。 这个新的研究项目将通过设计和建造，重点关注两个新颖且重要的内容：(i) 金属测试附片和 (ii) 具有卓越热交换能力的加热器，以混合试验橇并模拟现场 OTSG 侵蚀和腐蚀条件。 这项创新将需要进行系统研究，以确定水垢和污垢的成分以及对阻碍传热的影响，以及促进它们在沉积物下金属表面停留的侵蚀和腐蚀机制。
