Breaking News About Biofuel Development In China

Under the Chinese plan, coal use will be cut nationwide, and polluting industries will be shut down stringently. The central government promotes cleaner production in a bid to clean up the environment, aiming to cut coal consumption to below 65 percent of total primary energy use by 2017. Apart from that, the Chinese Government pledged to invest 1.7 trillion yuan ($277.32 billion) in the fight against air pollution over the next five years.

In this regard, more and more people started to focus on biofuel application, in particular, the use of biomass pellets which is counted as a green and renewable fuel replacement. However, of the biomass pellets fuel, wood pellets and agro pellets fuel are classified as two kinds of new fuel due to the different raw material types put into production. Therefore, we hereby can briefly discuss about the differences of the two.

As shown in the table, Wood's lignin content at 25% or higher lends itself to supreme quality and favorable durability due to lignin's thermoplastic nature that essentially melts and binds mealy particle together into pellets. Compared with it, crop residues and perennial grasses on the other hand typically contain lignin ranging from 12% to 14%, due to which more energy to pelletize herbaceous feedstock is needed than woody biomass, said INL researchers, unless binding agent is put into use.



In light of the different characters of distinctive materials per se, technological process of pelletization may be varied. Therefore, it is widely acknowledged that binders will from time to time be applied. However, some pellet mill manufacturer or supplier to sell their products decieves and makes deceptive guarantee that their pellet mills are capable of processing a lot of biomass materials without use of binders. Eventually, your production cannot continue smoothly when you actually put the machine into production. That's why it is necessary to point it out herewith. You are also supposed to ask for detailed info about pellet mill compression ratio and what kind of raw material their pellet mill can process when you contact your pellet machine supplier. Different raw materials demand for distinguished compression ratio of pellet mill mold and the project may be altered if you are going to start a pellet plant.

Actually, ash content also differs, along with varying levels of other elements such as clorine and silica. Because they may cause problems for power and industrial users, contributing to fouling or slagging in boilers. One possible solution to get better-quality pellets fuel from agro biomass is to blend multiple feedstocks to get a consistent content in Btu, ash content and moisture and to keep undesirable components in acceptable concentrations. Including 10-20% woody biomass in the blend can act as a binder improving durability of agro-based pellets fuel. Therefore, Finding a solution for durability and whetherability of  agro pellets has been focus of some pellet machine supplier. Becuase they know the improvement in technological process enables power plants to be effective and continue to provide baseload power but still balance the requirement of environment regulations and renewable portfolios and make the transformation from conventional coal-fired power plants into CHP or biomass fuel-combusting power plants way easier.
