Just how to pick appropriate wood pellet fuel for your boiler?<br>
richi pellet fuels are constructed from sawdust or plant wastes. By pressing and molding, they become strong strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the same energy density as medium coals. The burning impact has actually boosted a great deal compared to large products. Besides, wood pellet fuels are convenient to store and transportation.



Which has greater expense performance?

The high quality of biomass pellet fuel differs with the raw materials it is made. Typically, there are top quality sawdust pellets, usual wood pellets, bamboo pellets, peanut shell pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medication deposit pellets, organic sludge pellets, etc. They have various rates, residential properties as well as application areas and also target at particular clients.




For venture and also personal individuals, it is not important to choose high-quality sawdust pellets or low-price rice husk pellets all the time. You must pick the wood pellets with high cost efficiency and also fits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a common biomass pellet fuel It has reduced rate and also inferior high quality than sawdust pellets. Besides, it has narrower application locations than sawdust pellets.



High quality sawdust pellets can be applied in large stokerfeed boiler, taken care of grate boiler, heater, hot-blast oven, smelting heater, etc. Although the rate is higher than rice husk pellets, sawdust pellets is in terrific demand. In high periods, the top quality wood pellet supply remains in scarcity.



Which wood pellet boiler do you utilize?

For fixed grate boiler or little pellet burner, you must select those without coking.

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

For smelting heater, the wood pellets must have high heat worth as well as the volatile dividing price is high.

For thermal oil boiler, the wood pellets need to have low ash material without coking, and also the heat value and also the unpredictable separating rate is high.

Stockerfeed stoves have wider adaptability to wood pellets. manual animal feed pellet machine must take into consideration the heating rate need, automatic or manual slag tool, flue gas warm recovery tool, dirt collection agency kinds and also pick the most appropriate wood pellets.




Actions to choose suitable wood pellet fuel.

Based on years of my experience on biomass pellet fuel manufacturing as well as biomass boiler advertising and marketing, I wrap up the complying with steps on exactly how to choose appropriate wood pellet fuel.



Step 1: assess your wood pellet stoves and boilers

Action 2: list your demand on the wood pellet fuel

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

Step 4: compare the result of step2 and also step3, and also learn the suppliers that fulfill your requirements

Tip 5: exercise the unit cost based upon the delivered price offered by the wood pellet suppliers.

Select 2 or 3 vendors and assign the acquisition quantity proportionally. Keep in mind to sign contracts to safeguard a sufficient supply.

Notes:

As a mature wood pellet consumer, you must not only concentrate on the price of pellets or the device cost of warm worth, but take note of the system price of 1-ton steam manufacturing, including the cost of fuel, labor, maintenance, and slag therapy.



Take the after-sale solution right into consideration. Some wood pellets makes can offer boiler updating and also team training solution.



Quality indicators of wood pellet fuel

For usual uses, wood pellets fuel needs to meet the complying with specifications. The size is 6-12mm, the size is 2-4 times that of diameter, and also the bulk density is larger than 600kg/m3. The crushing price is much less tan 1.5%-2.0%, the ash material is lower than 1.5%, the sulfur and also chlorine content must be less than 0.07%, nitrogen content less than 0.5%, and also the warm worth is greater than 16MJ/kg.



For commercial purpose, wood pellets typically have the diameter of 8-10mm and the size of 25-35mm.



What's the very best thickness for making wood pellets?

Density is a crucial sign of wood pellet top quality. In many situations, the density of wood pellet fuel is between 1.1 as well as 1.3 t/m3. High density will boost the cost of production. Besides, high density requires high compression ratio, thus boosting the abrasion of molding dies and shortening their functioning life.



As a result, we advise to restrict the wood pellet thickness between 0.8 and also 1.1 t/m3. Several starters in wood pellet market like to make pellets with high density and high solidity. Although they looks stunning, they will decrease the production and also enhance the abrasion.
