TORFTECH LATEST TECHNOLOGY – RICE HUSK FOR POWER GENERATION

印度是农业富国。沿着其他农作物稻壳也广泛种植在印度大陆。1980年,稻壳成为蒸汽锅炉的主要燃料,以吸收工业蒸汽和电力需求。印度工业正在使用炉排/ AFBC燃烧技术在蒸汽锅炉炉中烧稻壳。稻壳含有18-20%的灰分,进一步含有95-98%的二氧化硅。所有蒸汽锅炉都使用75至82%的热效率,灰分中的碳含量为3-7%。

ASH coming out of convention grates/ AFBC is Crystalline Silica which is not for any use and disposal is a Big problem, even it is carcinogenic also.MAGO THERMAL with their Collaborator M/s Torftech Group, U.K . introduces latest combustion technologies which ensures Carbon in ASH less than 1 % and 100 % Amorphous silica in ASH.

Currently India is importing 50 % of SIlica of Its total requirement and balance 50 % is getting extracted from SAND but in future there shall be a BIG problem in Getting Sand.We as MAGO-TORFTECH is with latest technology which will not only reduce your fuel bill but also give you cost of your RICE HUSK ASH > TORBED* Energy Technology Application Description Torftech ENERGY & AMORPHOUS SILICA PRODUCTION FROM RICE HUSK.

Global production of rice, the majority of which is grown in Asia, is approximately 550 million tonnes/year. The milling of rice generates a waste material-the husk surrounding the rice grain. This is generated at a rate of about 20% of the weight of the product rice, or some 110 million tonnes per year globally. The husk in turn contains between 15 and 20% of mineral matter the majority of which is amorphous silica. There is a growing demand for finely divided amorphous silica in the production of high strength, low permeability concrete, for use in bridges, marine environments, and nuclear power plants. This market is currently filled by silica fume. IN INDIAN contest Limited supply and high demand has pushed the price of silica fume to as much as INR 50,000/tonne in some markets. Rice husk has the potential to generate 16.5 to 22 million tonnes of ash containing over 90% amorphous silica that could be used as a substitute for silica fume.

Rice husk is currently being used for energy production through direct combustion orgasification in many areas of the world. Unfortunately, in almost all of these installations, the ash produced is not suitable for use as a silica fume substitute.Generally there are two-shortcomings in the ash by-product from current rice husk to energy technology: first, they cancontain unacceptably high concentrations of residual carbon; and second a portion of the amorphous silica has been transformed into crystalline silica, cristobalite.

The second of these two problems is the more serious; cristobalite does not have the same pozzolanic (cementitious) properties, as the amorphous form, and in the particle size range at which it would be used in concrete, it is recognized as a potential human carcinogen. The transformation to the crystalline state takes place if the ash is exposed to high temperatures and becomes even more likely if it is exposed to these high temperatures for extended time periods. Most of the current energy generation technologies do not control temperatures well and most allow the ash to remain at high temperatures for a relatively long residence time TORBED Process Reactors applied to rice husk combustion and gasification technology utilize a unique reactor configuration that completes the combustion or gasification of husk in a short residence time at precisely controlled temperatures. It has been shown that,using the TORBED reactor technology, an ash can be produced at a moderate temperature that has zero or at mosttrace quantities of cristobalite and a residual carbon content of 1-4 %.

由于在托架反应器中使用的温度温度,可用的能量略有降低,可以从用作稻壳燃烧器的托架反应器中回收。然而,在某些情况下,可以通过实现可用燃料的更完整的燃烧来补偿。托架反应器可以设计成新设施,以燃烧稻壳的能量生产,或者这种燃烧器可以改装成现有设施以更换产生不可用的灰尘废物的电流燃烧器。基于将废物处理成本转化为副产品信贷的好处,替代燃烧器中的资本投资将产生有吸引力的投资回报('ROI')。类似地,为能量产生的新工厂的安装将基于能量和灰分值产生有吸引力的投资回报率。
