Steam Superheaters in Industrial Boilers. The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to …

and boiler technology. Water-cooled, vibrating grate (VG) boilers are an established technology for power generation from wood residues. Based on natural circulation, these boilers are designed to burn low-heating-value (i.e., LHV of about 13.8 MJ/ kg) wood residues with 30% humidity. The typical power plant capacity is on the order of 10 MWe.
