R&D Projects

B-1　BRIGADIER Project

(Brown Coal IGCC with Advanced Drying System by Internal Energy Recuperation )

There is an abundant coal reserve - lignite or brown coal. However, brown coal is not fully utilized today because of its high moisture content.
We will develop a new highly efficient drying system for brown coal by adopting a new approach, i.e. " internal energy recuperation". Our target is to reduce the heat loss due to drying by half. (Joint R&D project with Professor Tsutsumi of IIS)

B-2　ANGUS Project

(Anthracite Gasification for Universal Services )

Anthracite is also not commonly utilized today because of its poor ignition due to an extremely high fuel ratio ( fixed carbon/volatile matter).
An anthracite firing boiler needs special consideration to cope with this poor ignition.
By coal gasification, anthracite can be gasified stably and efficiently by the high combustion temperature of 1800℃ or more.
A large capacity, highly efficient gasification system for anthracite will greatly accelerate the use of anthracite both for chemical products and power generation.

B-3　DUNCAN Project

(Dry Unwashed Gas Clean-up System with Advancement and Novelty )

By adopting a dry clean-up system, the IGCC efficiency can be raised by as much as 2%. Yet most of the IGCC′s today adopt a wet coal clean-up system because of its confirmed performance and reliability through many years of commercial application. New dry clean-up systems with innovative catalysts will be studied.

B-4　COUGER Project

(Coal Gas Utilization for Gas Engine with Recuperation )

In recent years natural gas fired gas engine has lost its competitiveness due to the steep increase in the price of natural gas. Coal gas or substitute gas from coal obtained by the gasification of coal can be used as an alternate fuel for gas engines.
Well-engineered coal gas engines with effective heat exchange and recuperation systems will enable the revival of competitive gas engines.

B-5　ALBACORE Project

(Alteration of Bay Area fuels from Natural Gas to Coal Gas to Realize Energy Renaissance )

Natural gas is clean and free from corrosion or erosion. Moreover, it has the least CO2 emissions among fossil fuels. However, plants exclusively designed for natural gas only have vulnerability ― no consideration for erosion, corrosion and plugging ― which makes it impossible to be converted to other fuels, such as heavy oil or coal. If heavy oil or coal is gasified and cleaned, the product gas can be easily used in existing natural gas firing plants with minimum modification.
This will be especially effective in the Tokyo metropolitan bay area where natural gas firing plants and facilities exist in concentration, to prepare for an unexpected crisis in natural gas supply.
