as we following and study all serious info about WTE and latest CHP technologies, please send me also the details of your mentioned Waste Gasification / Thermal Oxidation Plant (WG / TO) system. Can you inform us also where this technology was running ?

Thanks, Max

Thanks for sharing this information.The technology looks interesting. I would like to know more about the capacity and cost of your system. Kindly write to me at bioenergyconsult [AT] gmail.com

Best wishes

The Waste Gasification / Thermal Oxidation Plant (WG / TO) is a two-stage waste combustion process that converts combustible organic matter from its existing solid, sludge or liquid state into a gas under an oxygen depleted environment (also known as “oxidation”). The resulting gas product is then well mixed with ambient air before being burnt off (flared) in a secondary gas-processing unit.

The WG / TO is comprised of three basic components: a Primary Gasification Cell, a Secondary Gas Processor, and a computerized Process Logic Controller. Combustible waste material is placed into the primary gasification cell through the load access door. In some facilities this can be done via a loading conveyor. The proposed design is to have collection vehicles dump their Municipal Solid Waste (MSW) load directly into the primary oxidation cell.

The Primary Cell can be either a batch or continuous feed processor. Based on our experience, batch processing provides the most efficient and cost effective strategy for the waste management solution. In the case of batch processing once the cell has received that days collected waste, the door is closed and the process is initiated. The cell does not have to be full for the system to be activated.

An operator is responsible for supervising the loading of waste material, and initiating the process start-up. A computer keystroke (or optional manual button and lever control) which pre-heats the secondary gas-processing unit accomplishes this start-up. Once that unit reaches its pre-set temperature, the primary gasification cell heater is activated, and the process begins. 8 to 12 hours later, the organic wastes in the primary cell will have been converted to a gas, and the cycle will generally be complete.

With the help of the Process Logic Computer (PLC) , the operator can evaluate the end of the gasification cycle by observing the change in oxygen content of the stack gas in the primary cell, and a predictable deadline in the primary cell temperature. Once these final conditions are reached, the PLC will indicate to the operator that the cycle is finished, and the system will move to its “cool down” mode. In another 4-6 hours, the system may be re-loaded, and another process started, with or without the removal of the preceding load’s ash material.

Residual materials (bottles, cans, ash and misc.) need only to be removed periodically. The composition of MSW consists mainly of organic and combustible waste. Glass and metals are easily extracted in our plant design as it includes equipment that will assist in the process and cut down on labor man-hours. Ash removal is either an automated or manual process. In automated unloading, the base of the primary gasification cell contains a ductile iron furnace floor conveyor that evacuates material remaining in the base of the unit through a side access door. This dry waste material empties into a storage bin, which can be removed to another location for recycling.

Instead of landfilling the garbage, burning it reduces green house gas emissions, boosts recycling (because those metals are worth a pretty penny), and eliminates the NIMBY syndrome of future landfill sites. But as long as the coal lobby has the upper hand they will do their best to conceal the fact that coal fired power plants account for >80% of the mercury being released into the environment, that account for the high concentrations of mercury in great lake’s fish, and polar marine life.

In China, 1 new coal fired power plant is opened every five days. When I was in Shanghai, ships sped furiously upriver to provide the hungry power plants with an abundance of coal. Sometimes you had 15 boats one after the other, like rail cars crowding the river. As long as the status quo (energy barons benefiting from the sale of coal and petrol) has it’s hand in the game, there will be no room made for true alternatives using free resources and comparatively benign technologies (WTE).

As Machiavelli rightfully stated: “It must be considered that there is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things. For the reformer has enemies in all those who profit by the old order, and only lukewarm defenders in all those who would profit by the new order, this lukewarmness arising partly from fear of their adversaries, who have the laws in their favour; and partly from the incredulity of mankind, who do not truly believe in anything new until they have had actual experience of it. Thus it arises that on every opportunity for attacking the reformer, his opponents do so with the zeal of partisans, the others only defend him half-heartedly, so that between them he runs great danger.”
