Exactly how to pick suitable wood pellet fuel for your boiler?<br>
Wood pellet fuels are made of sawdust or plant wastes. By pressing and also molding, they end up being solid strips with the thickness of 0.8-1.4 t/m3. Wood pellets fuel has the very same power density as tool coals. The burning impact has actually improved a great deal compared with cumbersome products. Besides, wood pellet fuels are convenient to store and transport.



Which has greater expense performance?

The high quality of biomass pellet fuel differs with the raw materials it is made. Generally, there are top quality sawdust pellets, typical wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medication deposit pellets, organic sludge pellets, and so on. They have different costs, homes and also application areas and target at specific customers.



For business as well as personal individuals, it is not wise to choose top quality sawdust pellets or low-price rice husk pellets all the time. You should pick the wood pellets with high price efficiency and matches your biomass boiler.



Rice husk pellets vs sawdust pellets

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



Excellent quality sawdust pellets can be used in big stokerfeed boiler, dealt with grate boiler, heater, hot-blast stove, smelting furnace, and so on. Although the cost is higher than rice husk pellets, sawdust pellets remains in wonderful need. In high seasons, the excellent quality wood pellet supply remains in shortage.



Which wood pellet boiler do you utilize?

For fixed grate boiler or tiny pellet burner, you must choose those without coking.

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

For heating heater, the wood pellets need to have high warm worth and the unpredictable dividing rate is high.

For thermal oil boiler, the wood pellets ought to have reduced ash content without coking, and also the warm value and the unstable separating rate is high.

Stockerfeed cooktops have larger flexibility to wood pellets. You ought to take into consideration the home heating price demand, automatic or manual slag tool, flue gas heat healing tool, dirt collector kinds and also pick the most appropriate wood pellets.



Actions to choose ideal wood pellet fuel.

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



Step 1: assess your wood pellet ranges as well as boilers

Step 2: list your requirement on the wood pellet fuel

Action 3: study the wood pellet manufactures within 800 kilometres, and also learn more about the homes of their wood pellet fuels

Step 4: contrast the result of step2 as well as step3, and also figure out the suppliers that fulfill your needs

Tip 5: work out the system cost based on the provided cost supplied by the wood pellet suppliers.

Pick 2 or 3 distributors and also designate the purchase amount proportionally. Bear in mind to sign agreements to secure an ample supply.

Notes:


As a mature wood pellet consumer, you need to not just concentrate on the cost of pellets or the unit cost of warmth value, yet pay attention to the system cost of 1-ton steam production, including the expense of fuel, labor, maintenance, as well as slag therapy.



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



Quality indicators of wood pellet fuel

For usual usages, wood pellets fuel has to fulfill the following parameters. The size is 6-12mm, the size is 2-4 times that of size, as well as the bulk density 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 as well as chlorine web content should be less than 0.07%, nitrogen content less than 0.5%, and the warmth value is more than 16MJ/kg.



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



What's the most effective density for making wood pellets?

Density is an important indication of wood pellet high quality. In a lot of situations, the thickness of wood pellet fuel is between 1.1 and also 1.3 t/m3. High density will certainly enhance the price of production. Besides, Richi machine requires high compression ratio, thus raising the abrasion of molding dies as well as reducing their working life.



Therefore, we recommend to constrain 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 gorgeous, they will certainly lower the manufacturing and also boost the abrasion.
