The Worldwide Leader in Biomass Gasification Technology
In addition to the rated electrical power there is process heat. A typical 1MWe system will provide around 1.8Mw of heat recovered from both the generator set exhaust (550 degC), the engine radiator (75 degC) and the heat from gas cooling. This heat can be utilised for any purpose, such as a district heating scheme, wood chip drying, crop drying, greenhouse heating, etc..
Electric power - at start-up a source of 3 phase electricity (grid or small diesel or gas genset) is needed for the electricial control and data systems and the start-up blower
Water Supply - the system uses a small amount of clean water
Powermax gasification plants tackle two major local problems: elimination of local waste and cost of energy. By converting local feedstock into energy you lower your costs and you create new revenues (i.e. selling electricity on the grid). Energy produced through Powermax gasification is renewable and is supported by your local renewable energy support policies.This model of circular economy is also an opportunity to increase your energy independence and it creates local employment.
Powermax doesn’t provide expert services on plants operating with other technologies.
Powermax can assess how Powermax gasifier or Powermax gas purification system could substitute your initial technology. However, we usually recommend replacing both gasifier and gas conditioning unit . In extreme cases, engine and biomass preparation units should be adapted.
The gasification process has been used for well over 180 years. Until the widespread availability of natural gas in the 1950’s, coal gasification was used to produce the gases used in many city street lights. Commercial development was not seriously explored for decades due to the expanding use of less-expensive petroleum-based products. During the oil crisis of the 1970’s, research and development in biomass gasification technologies were once again brought to the forefront.
Biomass is organic matter- and Biomass energy development likes to take what is usually thrown away and turn it into energy. Our technology, the Powermax Gasification Process allows business and industry to operate “off the grid” using their own waste stream (pallets, boxes, paper), or materials from agriculture such as farming, milling and ranching. We use clean technology to take the stored energy from these materials and create heating, electricity, even cooling through CHP (Combined Heat and Power).
Powermax can produce dozens if not hundreds of employment opportunities for local communities when a plant project is developed. There are a number of different sectors where jobs can be created: construction, farming, harvesting, feedstock transportation, feedstock preparation and plant maintenance. Because often times our plants will be built in rural areas, the impact can be very welcome and have a dramatic improvement on the local economy.
The gas mixture produced by the gasifier can be used for process heating applications by operating the gasifier in a forced draft (positive pressure) mode and passing the gas directly to a burner on a boiler to make steam for an electrical turbine generator or directly to an internal combustion engine.
The gas from the gasifier (Syngas) is basically composed of carbon monoxide (CO), hydrogen (H2), and nitrogen (N2). The CO and H2 is the combustible portion of the Syngas. It is used similar to natural gas, but it typically has lower energy content. This makes it an effective way to transfer the energy in the feedstock into Syngas to run a steam turbine or generator. Therefore the Syngas is cleaned and it is piped to the turbine or genset, the exhaust is cleaned with state-of-the-art emission control equipment after it has been burned as a fuel. In this way, reliability of the control equipment and quality of the exhaust gas stream are assured to meet all applicable air quality standards.
A Powermax gasifier can accept a range of feed stocks and thus the technology supports a bio-diverse resource base rather than a monoculture energy crop. However the energy density of the gas is far lower than that of liquid bio-fuels, making it more suitable for stationary applications than transport.
Biomass production also removes the same amount of CO2 from the atmosphere as is emitted from gasification.
While other biofuels technologies such as biogas (from landfills) and biodiesel (from agricultural sources) are carbon neutral too, gasification can operate on a wider variety of input materials and can be used to produce a wider variety of output fuels.
Gasification is a clean, affordable and environmentally sound renewable form of energy that provides a solution to forest and agricultural management residue issues we have right now. Another challenge is energy security. Governments want to use their own resources to produce energy and provide energy independence. We need to displace some of the energy we are literally shipping in from other parts of the world, and, probably more importantly, wean ourselves from dependence on foreign energy suppliers.
Wind and solar power are key components to the future electricity generation mix because they are low maintenance and greenhouse neutral. Solar generation has the advantage of peaking at the same time as peak air-conditioning loads, and wind energy when networked sufficiently widely with appropriate interconnection can provide base-load generation. However, neither can provide on-demand generation for load-matching – a problem that exists in everywhere, due to our remote location and “islanded” utility generation. Biomass gasification can provide this 24 hours a day, seven days a week, and, if supplied from sustainably-harvested fuel, it can be a truly greenhouse-neutral on-demand generation system to complement wind and solar in a carbon-neutral way.
1. The gasification of biomass as a feedstock produces Syngas. The Powermax gasifier is optimized to generate the maximum gas and little else. By products of the process are low-grade activated carbon or (Biochar) and some inert ash. Ideally, these by products are combined and returned to the soil as a soil conditioner re-capturing or sequestration of the carbon and nutrients in the soil. The Biochar then reduces the need for fertilizers which in turn improved the economics and waste due to farming. Waste heat is also produced by the process and can be used for water or space-heating, cooling, manufacturing processes, or for pre-drying the fuel for the gasifier.
2. Gasification reactions produce small amount of water, present in the form vapour at the outlet of the gasifier. If the syngas is to be cooled down (i.e. for powering gas engines), water condenses in the gas conditioning unit.
3. Tars that are separated by Powermax ESP(electrostatic precipitator) from the gas can be re-burned and used as fuel or can be sent back to reactor.
4. The syngas is sent directly to the internal combustion engines when used for electricity, the engine combusts the gas and any post emissions are treated in the engine system and catalytic converter meeting the engine manufacturers’ specifications for emissions if needed.
No. It heats the biomass fuel to create Syngas. The Syngas is directly consumed in an internal combustion engine to create electricity, or directly in a gas fired boiler to create steam, or other thermal applications where you can substitute Syngas for LPG or Natural Gas, not to dispose of waste.

However you can supply biomass with higher moisture content (up to 65 %wb). In that case, we install a biomass dryer powered by thermal energy recovered on the plant!
The integration and supply of a well suited biomass dryer is part of our complete offers.
Thermal conversion of biomass produces solid co-products; these contain various concentrations of mineral matters and carbon.Ashes refer to solid co-product of complete combustion of the solid feedstock. Ashes contain mineral matter initially present in the feedstock. Biochar refers to solid co-products of gasification: Unlike complete combustion, mineral matters leaving the gasifier are linked to some carbon content.
Powermax always believe there is none type of gasifier can use any kind of biomass, waste and coal. For different application different gasifier applied.
