Just how to pick suitable wood pellet fuel for your boiler?<br>


Wood pellet fuels are constructed from sawdust or crop wastes. By pressing and molding, they become solid strips with the thickness of 0.8-1.4 t/m3. Wood pellets fuel has the very same power thickness as tool coals. The burning result has actually improved a great deal compared with bulky products. Besides, wood pellet fuels are convenient to shop and also transportation.



Which has greater price performance?

The quality of biomass pellet fuel varies with the raw materials it is made. Usually, there are high quality sawdust pellets, common wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medicine deposit pellets, organic sludge pellets, and so on. They have various costs, residential properties and also application areas and target at particular consumers.



For venture as well as individual customers, it is not smart to pick top quality sawdust pellets or low-price rice husk pellets regularly. You need to pick the wood pellets with high cost efficiency and matches your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is an usual biomass pellet fuel It has lower price and also substandard top quality than sawdust pellets. Besides, it has narrower application areas than sawdust pellets.



High quality sawdust pellets can be used in large stokerfeed boiler, taken care of grate boiler, heater, hot-blast stove, smelting heater, etc. Although the cost is higher than rice husk pellets, sawdust pellets is in terrific need. In high periods, the high quality wood pellet supply is in lack.



Which wood pellet boiler do you utilize?

For fixed grate boiler or little pellet heater, you need to select those without coking.


For hot-blast range, the wood pellets must have reduced ash content as well as no coking.

For smelting furnace, the wood pellets need to have high heat value and the volatile dividing price is high.

For thermal oil boiler, the wood pellets ought to have reduced ash material without coking, and the warmth worth and the unpredictable dividing price is high.

Stockerfeed stoves have broader flexibility to wood pellets. You need to take into consideration the home heating rate demand, automated or hand-operated slag tool, flue gas warm recuperation gadget, dust enthusiast types as well as select one of the most ideal wood pellets.



Actions to select ideal wood pellet fuel.

Based upon years of my experience on biomass pellet fuel production as well as biomass boiler advertising and marketing, I end the following steps on exactly how to select suitable wood pellet fuel.




Step 1: evaluate your wood pellet cooktops as well as boilers

Action 2: checklist your requirement on the wood pellet fuel

Step 3: study the wood pellet makes within 800 km, and learn more about the properties of their wood pellet fuels

Step 4: compare the result of step2 as well as step3, as well as learn the vendors that fulfill your needs

Step 5: exercise the device price based upon the provided rate offered by the wood pellet providers.

Choose 2 or 3 distributors and also allot the purchase amount proportionally.small animal feed pellet machinein mind to authorize contracts to protect a sufficient supply.

Notes:

As a mature wood pellet consumer, you should not only focus on the cost of pellets or the system expense of heat value, however focus on the system price of 1-ton vapor production, including the price of fuel, labor, maintenance, and also slag treatment.



Take the after-sale service right into factor to consider. Some wood pellets makes can provide boiler updating and personnel training service.



Quality indicators of wood pellet fuel

For common usages, wood pellets fuel has to fulfill the complying with parameters. The size is 6-12mm, the size is 2-4 times that of size, and the bulk thickness is larger than 600kg/m3. The crushing price is less tan 1.5%-2.0%, the ash content is less than 1.5%, the sulfur and also chlorine material should be less than 0.07%, nitrogen content less than 0.5%, as well as the heat worth is greater than 16MJ/kg.



For commercial purpose, wood pellets usually have the size of 8-10mm as well as the length of 25-35mm.



What's the best thickness for making wood pellets?

Thickness is an important indicator of wood pellet top quality. In many situations, the density of wood pellet fuel is between 1.1 and also 1.3 t/m3. High density will certainly increase the cost of production. Besides,biomass pellet makercalls for high compression ratio, therefore enhancing the abrasion of molding dies and reducing their working life.



For that reason, we recommend to confine the wood pellet thickness in between 0.8 and 1.1 t/m3. Lots of beginners in wood pellet industry choose to make pellets with high density as well as high firmness. Although they looks lovely, they will certainly decrease the manufacturing and also boost the abrasion.
