NRSW Scheduled Waste & Sludge Fired Boilers

Non-Recyclable Solid Waste (NRSW) / Scheduled Waste & Sludge Fired Boilers

Designed for sustainable combustion of challenging and extremely heterogeneous waste fuels

Submit your enquiry

TBWES NRSW-fired boilers efficiently convert non-recyclable solid waste, scheduled waste, and sludge into energy, ensuring safe disposal and reliable power generation.

Engineered with inclined reciprocating grate combustion systems and robust thermal recovery, these boilers ensure optimal performance despite variable waste quality of the extremely heterogeneous NRSW wastes while guaranteeing maximum and consistent steam output. Advanced emission controls minimise environmental impact, making them highly suitable for industries seeking landfill diversion, energy self-reliance, and compliance with circular economy goals.
