Palm Plantation Captive Power Plant
Usually one palm plantation of 20~30 thousand acres needs to be adopted a palm oil crushing plant, which electricity load is around 1700KW~ 1800KW. Taking into account the living electricity and other facilities usage, the captive power plant suitable capacity shall be around 2000KW. Since all the palm oil crushing plant equipments power voltage is 400V, therefore we choose the generator with output voltage 420V.
Palm oil crushing process requires lots of steam, and generates lots of palm empty bunches, palm fruit fibers, palm shells, kernels and other wastes. The special designed biomass boiler can burn these palm wastes and generate steam, which through back pressure turbine generator to generate electricity and then directly cooking the palm oil. This approach not only can meet the electricity and steam requirements, but also can solve the palm waste disposal problem.
Design Proposal
General principle: The equipment and system shall be safe, reliable, practical and easy to operate with mature process design.
Capacity: Single BTG unit, that is one palm waste fired boiler(35~45t/h) of sub-medium temperature and sub-medium pressure combined with one unit of 2000KW turbine generator(back pressure type).
Plant layout: Compact and reasonable arrangement with smooth access.
Fuel conveying system: Fuel is conveyed from the palm waste shed to the furnace hopper and fed in to the furnace for combustion.
Water system: Power plant water using river water or lake water(rainwater), the circulating cooling system is open cycle.
Chemical water: Using desalinization equipment, water pre-treatment +R/O system.
Electric system: Generator output voltage is 0.42KV, which will be connected to the owner's existing distribution room, with one 400V line to the power plant.
Control system: Boiler, turbo unit, generator, deaerator feedwater using single-loop control system, equipped with world well-know brand DCS + PLC.
Slag and ash handling: Using multi-tube dust remover, slag and ash will be transported outside by truck, no ash yard in the plant.
Proposal 1: Fuel of Plam Waste
Proposal 2: Fuel of Plam Waste + Biogas
