The Steam Accumulator as the cost-effective solution.
The plant already has a boiler of a certain capacity, but for some reasons, the process load requirement increases for a certain time period in a day while at other times, the process load requirement falls even below the maximum capacity.
Plants planning to install a boiler for their process must consider the average heat load requirement of their process for deciding the maximum boiler capacity, and for the overload conditions, the steam accumulator can be installed. It takes care of the jerk-load requirements, when the steam flow increases beyond the boiler capacity for a short interval, and would store the extra heat during the fall in steam requirement, thereby stabilising the process.
