Biomass-based power plants: The heat produced by direct biomass combustion in a boiler can be used to generate electricity via a steam turbine or engine. I report the emissions from generated electricity under Scope 2. The energy produced by biomass is known as bioenergy. However, in contrast to first generation biofuels, biomass combustion and co-firing today generally do not compete with food production, as they rely mostly on agricultural or wood residues. Skills Resume. Biomass consumption in 1994 reached approximately 3 EJ , Increasing energy security and saving foreign currency by reducing the dependence on imported fossil feedstock, such as coal. Two technologically mature and cost-attractive options involve burning biomass in standalone units or co-firing it with fossil fuels in standard thermal power plants. The utilisation of biomass is increasingly important for low- or zero-carbon power generation. The conversion process for this purpose must be flexible enough to accommodate various types of biomass. At present, some 230 power and combined heat and power (CHP) plants use co-ring, mostly in northern Europe and the United States (Platts, 2011b), with a capacity of 50-700 MWe. Therefore, it is a renewable resource for energy production using organic matter. Standalone Combustion Biomass based generators use diesel derived from vegetable oils to fuel diesel generators. This is a common scenario in many nations, including Sri Lanka. I - Direct Combustion of Biomass - Ralph P. Overend Encyclopedia of Life Support Systems (EOLSS) such fuels. The most common method of converting . The actual costs can very significantly however depending upon the specific site to be used, the existing installation (in the case of co-firing) and the cost of the biomass itself. At the same time, a proliferation of smaller-scale biomass-to-power or CHP projects has been ongoing in both developed countries and emerging economies. In the case a good match can be found between heat production and its demand, combined heat and power (CHP) plants, also called cogeneration plants, can have overall (thermal + electric) efficiencies in the range of 80-90%. A combustion progress pathway diagram was developed that describes the stages of the smouldering and flaming combustion of a single dry biomass particle. 1404). Instead of direct combustion, some developing technologies gasify the biomass to produce a combustible gas, and others produce pyrolysis oils that can be used to replace liquid fuels. 1.

Co-generation significantly increases the overall efficiency of a power plant (and hence its competitiveness) if there is an economic application for its waste heat (IEA Bioenergy, 2009). China, Brazil, Latin America, Thailand, and India are all increasingly employing biomass power alongside other renewable resources (IEA 2007). . Biomass are collected and transported to the power plant, generating electricity by direct combustion. Worldwide, it already provides over 90% of the energy generated from biomass, a significant part of which in the form of traditional uses for cooking and heating. There are three main stages to the combustion process as shown in Figure 1. 0000000729 00000 n Brazil, USA). Thermal Production of Low or Medium, The chapter focuses on recent trends of biomass conversion into valuable energy, chemicals, gaseous and liquid fuels. In Germany, DENA (2011) assumes a premium of 12/MWhe on top of coal, with future premiums ranging between 0-20/MWhe in 2030, depending on coal prices. As mentioned previously, burning wood is historically the most popular method of producing energy. For direct co-firing they typically average 2.5-3.5% of capital costs (IRENA, 2012) and approximately 5% for indirect co-firing (ECN, 2012b). The most important consideration when collecting biomass residues for energy use is to not to exceed the biological requirements of the soil (part of residues must be left on the field and on the forest floor to return vital nutrients to the soil). Reduced GHG emissions from the power sector. energy and moisture content).

Local availability of large quantities of cheap biomass makes biomass co-ring more economically attractive. The syngas from biomass can then be used for power generation or for utilization in the steel industry [6,7]. Today, biomass power plants are fueled by agricultural and forestry waste such as corn stover, wheat straw, rice husks and wood waste. IEA/ IRENA. Pyrolysis of biomass is a particularly attractive process if all three products - gas, wood tars, and charcoal - can be used. Surfaces in direct line with the stove will be heated. Further expansion of biomass combustion and co-generation will be limited by availability of cheap feedstock, which depends on local collection ability and logistics and development of energy densification technologies for imported biomass. Thermochemical conversion (combustion) could be achieved in a number of ways using varied feedstock. Fundamentals of Biomass Combustion 2.1. Since biomass is the only carbon-based renewable fuel, its application becomes more and more important for climate protection. Burning either fossil fuels or biomass releases carbon dioxide (CO 2 ), a greenhouse gas. Biomass fuel cost: this includes both the cost of the feedstock and the cost of transportation, preparation and handling. It can be divided into biomass gasification, gas purifying and gas power generation 3 steps. Direct co-firing can be done either by pre-mixed the raw solid biomass (generally in granular, pelletised or dust form), with the coal in the coal handling system or by the milling it and directly injecting it into the pulverised coal firing system. However, many small scale biomass electric plants are also available with a total cost of 3000 to 4000 per kilowatt. This process has the purpose of generating energy - heat, and electricity. A recent IRENA study provides feedstock cost data for a range of locally available biomass resources in the United States, Europe, Brazil and India (IRENA, 2012). The most common application of biomass energy in developing countries is its use as a Combustion is regarded as the most direct and simplest technology for thermally treating biomass to produce energy. Biomass is an interesting option for electricity and heat production in parts of the world where supplies of residues from agriculture or the forest products industry are abundant. However, low calorific value is one essential drawback that hinders the direct utilization of biomass . Biomass fuel is combusted in a furnace or boiler at between 800F and 1000F, producing heat and high-pressure steam. Taxes. 45 21 The rotation of the turbine drives a generator, producing electricity. Biomass is one form of renewable energy source used for both heat and power generation through direct combustion. The main product from direct combustion is heat. Determining the costs for biomass combustion and biomass co-firing involved analysing several components, in particular investment costs, operations and maintenance, and fuel. During combustion, biomass fuel is burnt in excess air to produce heat. vegetable oil, tallow) is also co-fired in existing plants on a commercial basis, however at a scale much lower than for the solid biomass. However, this price differential can be overcome if the price of CO2 emission allowances is sufficiently high. Direct Combustion The direct combustion of biomass in presence of oxygen/air to produce heat and by products is called direct combustion. Biomass power generation is a kind of renewable energy power generation using biomass energy, including agricultural and forestry waste direct combustion power generation, agricultural and . Operation and maintenance costs: for co-firing O&M costs are similar to coal-fired plants.

Direct co-firing: The biomass is burnt directly in the existing coal furnace. Direct Combustion of Wood for Energy Production A significant advantage of forest biomass is that it could be directly combusted. This technology only requires minor investment to adapt handling and feeding equipment without noticeably affecting boiler efficiency, provided the biomass is not too wet and has been pre-milled to a suitable size. wood pellets) can be used. Parallel co-firing units are mostly used in pulp and paper industrial power plants (IEA Bioenergy, 2009). For industrial applications, direct co-firing in large-scale modern coal plants is today the most cost effective use of biomass for power generation. Wood burning was the biggest energy provider for large countries like the U.S until the mid 19th century, homes were heated by it and factories fueled by it. A further advantage is that only a relatively small incremental investment is required to adapt existing coal-fired power plants into co-fired plants (IRENA, 2013). The utilisation of biomass is increasingly important for low- or zero-carbon power generation. Co-firing plants for those countries with coal plants; Combustion-based CHP plants for countries that possess district heating systems (Nordic countries in Europe), large pulp and paper or food industries (e.g. The biomass fuels usually considered range from woody to grassy and straw-derived materials and include both residues and energy crops. Increased income and jobs in the agriculture and forestry sectors, which now supply part of the feedstock used in power and heat production (agricultural and forest residues). The total energy efficiency can be increased even further if biomass co- ring takes place in combined heat and power (CHP) plants. Many agricultural and forest residues can be assumed to be carbon neutral, which leads to significant attributable GHG emission reductions. The Nature of Biomass Solid Fuels 3.1. In both cases, the biggest challenge is provision of a constant stream of biomass feedstock. It introduces the combustion process with a specific focus on issues important in the combustion of solid biomass such as the condition and chemical properties of the biomass fuel, the increased fouling and corrosion of heating surfaces associated with biomass compared to fossil fuels, as well as ash properties and sintering problems. Gasification process generates (700-1000C) heat energy with a combustible gas mixture, commonly known as producer gas or syngas, which can be used to make synthesize fuels or other chemicals using catalysts [ 17 ]. A common method of producing bio-energy is the direct combustion technique, whereby a variety of feed stocks are burned to produce heat for steam, which in turn, drives turbines, thus creating energy.
