How to pick ideal wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or plant wastes. By pushing and molding, they become strong strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the same energy thickness as medium coals. The burning impact has actually improved a whole lot compared to cumbersome products. Besides, wood pellet fuels are convenient to shop and also transport.



Which has greater expense performance?

The quality of biomass pellet fuel varies with the raw products it is made. Normally, there are premium quality sawdust pellets, common wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medication deposit pellets, natural sludge pellets, and so on. They have various prices, residential or commercial properties and application areas and target at details clients.



For business as well as personal individuals, it is not a good idea to select high-quality sawdust pellets or low-price rice husk pellets all the time. You should select the wood pellets with high price efficiency 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 cost as well as substandard quality than sawdust pellets. Besides, a knockout post has narrower application locations than sawdust pellets.



Excellent quality sawdust pellets can be used in large stokerfeed boiler, fixed grate boiler, heater, hot-blast stove, smelting heating system, etc. Although the price is more than rice husk pellets, sawdust pellets remains in great demand. In high periods, the top quality wood pellet supply is in scarcity.



Which wood pellet boiler do you make use of?

For dealt with grate boiler or little pellet burner, you ought to pick those without coking.

For hot-blast stove, the wood pellets need to have reduced ash web content and also no coking.


For smelting furnace, the wood pellets need to have high warmth value and the unstable separating rate is high.

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

Stockerfeed cooktops have bigger flexibility to wood pellets. You must take into account the home heating rate need, automated or manual slag tool, flue gas warm recuperation tool, dust enthusiast kinds and pick one of the most ideal wood pellets.



Steps to pick ideal wood pellet fuel.

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



Step 1: analyze your wood pellet stoves as well as boilers

Action 2: checklist your requirement on the wood pellet fuel

Step 3: study the wood pellet produces within 800 kilometres, and learn about the properties of their wood pellet fuels

Tip 4: compare the result of step2 and step3, and find out the vendors that fulfill your demands

Step 5: exercise the unit expense based upon the delivered cost given by the wood pellet vendors.

Select 2 or 3 providers and also designate the acquisition amount proportionally. Bear in mind to authorize agreements to secure an ample supply.

Notes:

As a mature wood pellet consumer, you need to not just concentrate on the rate of pellets or the unit price of heat worth, however take note of the device expense of 1-ton vapor production, consisting of the cost of fuel, labor, upkeep, as well as slag treatment.



Take the after-sale solution right into consideration. Some wood pellets manufactures can offer boiler updating as well as staff training solution.



Quality indications of wood pellet fuel

For common uses, wood pellets fuel has to fulfill the following specifications. The size is 6-12mm, the size is 2-4 times that of diameter, and the bulk thickness is larger than 600kg/m3. The squashing rate is much less tan 1.5%-2.0%, the ash web content is less than 1.5%, the sulfur as well as chlorine material should be less than 0.07%, nitrogen content less than 0.5%, and also the heat worth is higher than 16MJ/kg.



For commercial objective, wood pellets generally have the diameter of 8-10mm and also the length of 25-35mm.



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

Thickness is an important sign of wood pellet high quality. In a lot of scenarios, the thickness of wood pellet fuel is in between 1.1 and 1.3 t/m3. High thickness will raise the price of production. Besides, high thickness needs high compression ratio, thus increasing the abrasion of molding dies and shortening their working life.



Therefore, we recommend to constrain the wood pellet density in between 0.8 and also 1.1 t/m3. Lots of beginners in wood pellet industry like to make pellets with high thickness and high hardness. Although chicken manure pellet machine looks stunning, they will reduce the manufacturing as well as raise the abrasion.
