CBC Indústrias Pesadas S.A. (CBC), a Brazilian group company of Mitsubishi Hitachi Power Systems, Ltd. (MHPS), has simultaneously received orders from Klabin S.A., one of Brazil's leading pulp and paper manufacturers, for one of the largest-capacity recovery boiler in the world and a high-performance, large-capacity biomass-fired boiler. The two boilers will form the core components in Klabin's Puma Project to create one of the largest pulp and paper manufacturing plant in the world. Delivery of both boilers is scheduled up to the end of February 2016.
The two large-size boilers will be installed in a state-of-the-art plant being built in the municipality of Ortigueira in Paraná state, Brazil. The boilers will support the production of pulp at the plant, which will reach 1.50 million tons per year.
The high-efficiency recovery boiler on this order will feature one of the largest capacity in the world, with ability to process 7,000 tons per day (in solid matter parameters) of black liquor, a liquid used as boiler fuel which is produced during pulp processing. Currently, the largest capacity of pulp and paper production plants in Japan is 2,700 tons per day. On the other hand, in recent years the global trend is moving toward state-of-the-art plants with capacities exceeding 5,000 tons per day. The large-capacity recovery boiler on this order is intended to respond to such demand.
The newly ordered biomass-fired boiler will be used for high-efficiency burning of biomass (woody) fuel components produced in association with pulp production: e.g., wood rejects and shredded bark. Incorporating CBC's bubbling fluidized bed (BFB) technology, the boiler features a steam generation volume of 280 tons per hour, making it one of the largest-capacity boilers fired with biomass fuel in Brazil.
In addition to the two boilers, CBC will also supply Klabin with auxiliary equipment such as combustion system and stacks. CBC will also handle all related transportation, installation, commissioning and test operation guidance, etc. as a turn-key project.
