COMBIPAC Biomass Boiler Model: CPRG160 with Reciprocating Grate using Lambion, GmbH Technology

Boiler Capacity: 16 TPH
Site Location: Pune, Maharashtra
Fuel: Biomass Briquettes
Estimated CO2 Reduction: 15,600 TPA

Project Overview

The customer’s manufacturing unit was operating with 5 boilers for generating process steam, out of which 4 were oil-fired (subsequently two were retrofitted to run on biomass) and 1 was biomass-fired. Due to process expansion and hence an increase in the steam demand, the following was observed:

  • Existing retrofitted boilers, being manual fired and inefficient, were unable to deliver economically.
  • The retrofitted boilers were unable to consistently meet the environmental standards in spite of Bag Filters being installed.
  • The retrofitted boilers had also run their lifetime and were unsafe to operate, thus requiring high maintenance costs.
  • More furnace oil was required to meet the enhanced demand which further added to the cost of production.
