How to choose suitable wood pellet fuel for your boiler?<br>
Wood pellet fuels are made of sawdust or crop wastes. By pressing and molding, they end up being strong strips with the density of 0.8-1.4 t/m3. richi machinery has the same energy density as tool coals. The burning result has boosted a great deal compared to large materials. Besides, wood pellet fuels are convenient to store and also transportation.



Which has higher expense performance?

The quality of biomass pellet fuel varies with the raw materials it is made. Normally, there are high quality sawdust pellets, typical wood pellets, bamboo pellets, peanut shell pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medicine residue pellets, organic sludge pellets, etc. They have various costs, residential properties as well as application areas as well as target at certain consumers.



For business as well as personal users, it is not a good idea to choose premium sawdust pellets or low-price rice husk pellets constantly. You should pick the wood pellets with high cost performance as well as fits 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 quality than sawdust pellets. Besides, it has narrower application locations than sawdust pellets.



Excellent quality sawdust pellets can be used in big stokerfeed boiler, fixed grate boiler, heater, hot-blast stove, smelting furnace, etc. Although the price is greater than rice husk pellets, sawdust pellets remains in excellent demand. In high periods, the excellent quality wood pellet supply is in lack.



Which wood pellet boiler do you use?

For fixed grate boiler or tiny pellet heater, you must select those without coking.

For hot-blast stove, the wood pellets should have low ash material and no coking.

For heating furnace, the wood pellets should have high warm value as well as the unpredictable dividing rate is high.


For thermal oil boiler, the wood pellets need to have reduced ash web content without coking, as well as the warm worth and the unstable dividing rate is high.

Stockerfeed ranges have bigger flexibility to wood pellets. animal food pellet machine ought to think about the heating price demand, automatic or manual slag tool, flue gas heat recuperation device, dust enthusiast kinds and also select the most ideal wood pellets.



Steps to choose suitable wood pellet fuel.

Based on years of my experience on biomass pellet fuel manufacturing and also biomass boiler marketing, I end the following steps on how to select appropriate wood pellet fuel.



Step 1: evaluate your wood pellet stoves and also boilers

Step 2: list your demand on the wood pellet fuel

Step 3: survey the wood pellet produces within 800 km, and also learn about the residential properties of their wood pellet fuels

Tip 4: contrast the result of step2 and step3, as well as learn the distributors that fulfill your requirements

Step 5: exercise the system price based on the delivered cost supplied by the wood pellet distributors.

Choose 2 or 3 suppliers as well as assign the acquisition quantity proportionally. Bear in mind to authorize agreements to safeguard an appropriate supply.

Notes:

As a mature wood pellet consumer, you should not only concentrate on the cost of pellets or the system price of warm value, however focus on the unit expense of 1-ton steam manufacturing, including the expense of fuel, labor, upkeep, as well as slag therapy.



Take the after-sale service right into consideration. Some wood pellets produces can supply boiler upgrading as well as staff training service.



Quality signs of wood pellet fuel


For usual usages, wood pellets fuel has to fulfill the following specifications. The size is 6-12mm, the length is 2-4 times that of size, as well as the mass 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 need to be less than 0.07%, nitrogen material less than 0.5%, and also the heat worth is more than 16MJ/kg.



For industrial objective, wood pellets usually have the size of 8-10mm and also the size of 25-35mm.



What's the best thickness for making wood pellets?

Thickness is an essential indicator of wood pellet high quality. In a lot of situations, the thickness of wood pellet fuel is in between 1.1 and also 1.3 t/m3. pla pellet extruder will certainly enhance the expense of manufacturing. Besides, high thickness requires high compression ratio, thus raising the abrasion of molding dies and also reducing their working life.



Consequently, we recommend to confine the wood pellet thickness in between 0.8 and 1.1 t/m3. Many starters in wood pellet industry prefer to make pellets with high density and also high firmness. Although they looks stunning, they will certainly minimize the manufacturing and also boost the abrasion.
