Abstract:The project aims to analyze a pilot plant for the direct combustion of hydrogen that must be realized by the company Stork Thermeq B.V. together with DNVGL. The system in consideration has a nominal power of 500 kW (LHV) and is designed to operate in a power range between 10% and 100%. Under stationary and standard conditions, hydrogen is burned with pure oxygen, produced by electrolysis of water, the reaction creates steam, which is recirculated to cool the combustion chamber at temperatures that are sustainable for the equipment. Moreover, the recycled steam is used to cool the combustion to avoid the production of NOx pollutants that would be created if the reaction was cooled with air. The plant can also operate with air or a mixture of nitrogen and oxygen introduced separately. The system also has the possibility to be powered by natural gas, in order to analyze the differences in combustion of the two different types of fuel and to implement the system for future commercialization. Since Stork Thermeq B.V. is a leading company in the production of boilers and burners, these two components will be analyzed in detail. The target is to give a flexible plant which can offer the chance to substitute the single parts of the system and measure the differences. The project therefore focuses on analyzing the plant from the point of view of the energy and mass balance in various conditions, standard and transition; analyzes various possibilities that can be developed. After defining a set-up for the plant, the individual equipment are sized and designed to be printed in 3D, P&ID’s and PFD’s are drawn for standard conditions. Finally, a proposal for the internal HAZOP analysis and a related philosophy of operation of the plant are drawn up.
