On 20 July 2018, the waste management association of the greater Würzburg area (ZVAWS) awarded MARTIN the design contract for partial replacement of line 1 of the Würzburg WTE plant.
Under the contract, MARTIN is to plan the scope of services to be performed: dismantling of the existing steam generator and grate as well as of various auxiliary units in line 1; erection of a new grate-based combustion system consisting of the MARTIN reverse-acting grate and associated steam generator, installation of various media pipes and of the electrical instrument and control system technology as well as replacement of the switchgear for line 2. Planning must take into account that lines 2 and 3 need to continue to operate while replacement work is in progress.
The new line is to be designed for a gross heat release of 29.2 MW, an average heating value of 10,500 kJ/kg and a waste throughput rate of approx. 10 t/h, while at the same time providing for the co-combustion of a certain amount of sewage sludge.
A binding contract for the implementation of planning work is yet to be awarded. This is expected to take place when design work has been completed, the permit has been obtained and the members of the waste management association have approved partial replacement, probably in June 2019.
