We are the manufacturers / suppliers of the unique CCE-SJG Gasproducer System and currently only produce four types of TAR FREE Gasifiers for electricity generation and / or heat applications in the following ranges:
1. A 120 Nm³/h, with a max output of 50kVA/ 40kWe (120kWe), or 180kWth
2. A 180 Nm³/h, with a max output of 80kVA/ 64kWe (200kWe), or 275kWth
3. A 300 Nm³/h, with a max output of 140kVA/120kWe (350kWe), or 460kWth and
4. A 450 Nm³/h, with a max output of 200kVA/166kWe (480kWe), or 685kWth
Max output in brackets denotes enhanced “dual fuel” operation.
These figures are from our naturally aspirated gas engines, but much bigger yields will be obtained from latest generation turbo charged engines. See below.
For electricity generation of 250kWe up to 3MWe we suggest that our 450Nm³/h units are used.
Our delivery scope includes the Gasifier and Cyclone, a Scrubber/Cooler, two Particle Interference Filters, one Heat Exchanger (if 1000L/h of 80?C hot water production is required), Cooling Pond and a system Control Panel. The systems are skid mounted (for easy transportation / installation) and will be factory tested before shipment. The current ex-works price for one unit is EUR 155,000.00.
Production time: max 16 weeks.
With reference to the FLOW DIAGRAM in the attached presentation, all civil construction- and peripheral system work as well as the Gensets are excluded, as these items should be sourced by respective clients for cost effectiveness. We have stopped suggesting European Gensets because their prices have tripled over the past years, due to the high feed-in tariffs in Europe. We have a local exclusive agent for Shandong Gensets, made under Cummings license in China. Our ex-works cost for a 250kWe turbocharged Genset would be around EUR 125,000.00.
If you need to put a budgetary project together, please don’t forget to include infrastructure costs for peripherals like civil works (concrete slab for Gasifier and Genset, simple roof structure and weather protection of feedstock storage, feedstock preparation area etc. If you want to use sawdust and / or small chips as feedstock instead of solid wood blocks, it has to be briquetted.
Factual info on the 450Nm³/h system’s Genset outputs are as follows:
166kWe using a naturally aspirated Genset engine in 100% gas configuration. Feedstock: max 225kg/h
250kWe using a turbocharged / intercooled Genset engine in 100% gas configuration. Feedstock: max 225kg/h
480kWe using a turbocharged / intercooled Genset engine in Dual Fuel configuration. Feedstock: max 225kg/h plus 16,5 litres of (bio)diesel/h. On 100% diesel operation, the consumption would be 82,5 litres/h.
The original plant concept of the above units was for underdeveloped countries, i.e. easy to operate (manually) and labour intensive (for job creation purposes).
Basic design data for bigger plants is available, but we have not yet undertaken industrialization due to little or no demand in previous years. But, due to the general energy crisis and the requirement for environmentally friendly power generation, we are now receiving more and more enquiries from Europe and other industrialized countries for larger tar free plants, which means that the outstanding detailed engineering and draughting work for workshop drawings, manuals etc. will still have to be done before we can propose such bigger plants.
Also, for North America, Europe and large parts of Asia, full automation is called for, in which case we are cooperating with capable engineering companies, not only for cost effectiveness, but also to cover local rules and regulations and to allow for the all important local content for such projects.
In Asia we have a licensee since 2005, Kawasaki Heavy Industries (Kobe/Japan). Our local Genset suppliers are Diesel Electric Services (Pty) Ltd. / Jhb. and Brondal for Shengdong (Cummins).
Our Gasifiers run on various types of woody biomass (or briquetted sawdust/chips/agricultural waste), powering Gensets with converted gas- or petrol engines and diesel engines, the latter in “dual fuel” operation, replacing up to 80% of diesel (biodiesel) fuel with CCE-SJG gas.
The fuel blocks for the 450 Nm³/h units for example must have the approximate size of 11cm long X 40cm² cross area, with a max allowable moisture content of 20%. Max fuel consumption for this unit is 225kg per hour.
The average effective heat value of biomass varies between 5900kJ/Nm³ and 6250kJ/Nm³ ÷ 4,1868 = 1409,19kcal/Nm³ and 1492,78kcal/Nm³.
As a “thumb rule” one can say that 1kg biomass produces 1kVA (0,8kWel) using naturally aspirated gas engines, but more than 1,5kVA (1,2kWel) can be achieved with turbocharged engines and 2,7kVA (2.1kWel) in dual fuel mode.
The weight of ash produced is 0.03kg/kg biomass.
The system is designed to run 24 hour / day!
Please note that it is important to find out what type of engine is intended to be used. A diesel / biodiesel engine in dual fuel operation is easy to convert, as it only requires a gas / air ratio adapter. The advantage of dual fuel operation is that the electricity supply will continue, if the biomass supply runs out for short periods of time for whatever reasons. However, for 100% gas operation, conventional SINA (spark ignited naturally aspirated), or turbocharged engines must be converted to biomass gas operation, due to the lower heat value of the gas, compared to liquid fuels,
Finally, may I suggest that you consult our website www.carboconsult.com, as it contains a printable brochure and will answer a host of additional questions which might arise.
I am looking forward to further dialog.
