This blog category covers EnerTherm Engineering's specialized heat recovery solutions tailored for the pulp and paper industry. Content should focus on the engineering, application, and maintenance of heat exchangers designed to operate in harsh, corrosive, and fibre-laden environments. Key topics include the recovery of thermal energy from recovery boilers, paper machine dryer sections, and process water streams. Articles should detail the use of SS 304L and SS 316L materials to combat acidic conditions and black liquor particulates, as well as design features like removable end covers and cleanable tube bundles that mitigate fibre fouling. The category encompasses technical insights into product lines such as the ThermStack TSE (445–800 kW) for flue gas, the EcoTherm EST (2,000–3,500 kW) for large-scale recovery, and the EnerAir EAA for paper machine hood exhaust. Content should address operational benefits, including 10–20% reductions in dryer steam demand, decarbonisation efforts (up to 4,466 tonnes of CO2 reduction annually), and strategies for integrating these systems into existing boiler houses and machine halls. Technical discussions should highlight capacity ranges from 250 kW to 3,500 kW, maintenance protocols for 6–24 month intervals, and the engineering considerations for structural loading and pipe routing during installation.
