Exactly how to choose suitable wood pellet fuel for your boiler?<br>
Wood pellet fuels are constructed from sawdust or crop wastes. By pressing and also molding, they end up being strong strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the exact same power thickness as medium coals. The burning effect has actually improved a lot compared with large materials. Besides, wood pellet fuels are convenient to store and also transport.




Which has higher price performance?

The quality of biomass pellet fuel differs with the raw products it is made. Generally, 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 residue pellets, organic sludge pellets, and so on. They have different prices, homes and also application places and target at specific customers.




For enterprise and individual users, it is not important to pick top notch sawdust pellets or low-price rice husk pellets regularly. You ought to choose the wood pellets with high expense efficiency and suits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is an usual biomass pellet fuel It has reduced price as well as substandard quality than sawdust pellets. Besides, pellet machine for sale has narrower application areas than sawdust pellets.



Top quality sawdust pellets can be applied in big stokerfeed boiler, fixed grate boiler, heater, hot-blast stove, smelting heater, etc. Although the cost is more than rice husk pellets, sawdust pellets remains in great demand. In high periods, the top quality wood pellet supply is in shortage.



Which wood pellet boiler do you utilize?

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

For hot-blast stove, the wood pellets must have reduced ash content and no coking.

For smelting heater, the wood pellets must have high warm value and the unstable dividing price is high.

For thermal oil boiler, the wood pellets should have reduced ash web content without coking, as well as the warm value as well as the volatile dividing price is high.

Stockerfeed ovens have bigger versatility to wood pellets. You ought to take into account the heating rate need, automatic or hand-operated slag device, flue gas warm recuperation gadget, dust collection agency types and also choose the most suitable wood pellets.



Steps to select appropriate wood pellet fuel.

Based upon years of my experience on biomass pellet fuel manufacturing and biomass boiler advertising and marketing, I conclude the adhering to steps on how to choose suitable wood pellet fuel.



Step 1: examine your wood pellet cooktops and also boilers

Step 2: list your need on the wood pellet fuel

Action 3: study the wood pellet makes within 800 km, and find out about the properties of their wood pellet fuels

Tip 4: contrast the outcome of step2 and step3, as well as learn the suppliers that meet your demands

Step 5: exercise the device cost based on the provided cost offered by the wood pellet suppliers.

Choose 2 or 3 suppliers as well as allocate the purchase amount proportionally. Remember to authorize machine to make pellets to safeguard an ample supply.

Notes:

As a fully grown wood pellet consumer, you need to not just concentrate on the cost of pellets or the unit cost of warm worth, yet take note of the unit expense of 1-ton vapor manufacturing, including the expense of fuel, labor, upkeep, as well as slag treatment.



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



Quality indications of wood pellet fuel

For common usages, wood pellets fuel has to meet the complying with parameters. The diameter is 6-12mm, the size is 2-4 times that of size, as well as the mass thickness is larger than 600kg/m3. The squashing price is 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 the warm worth is more than 16MJ/kg.



For commercial objective, wood pellets normally 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 indicator of wood pellet top quality. In most circumstances, the thickness of wood pellet fuel is in between 1.1 and also 1.3 t/m3. High density will increase the cost of production. Besides, high density requires high compression ratio, thus boosting the abrasion of molding dies as well as reducing their working life.



Consequently, we advise to restrict the wood pellet thickness in between 0.8 and 1.1 t/m3. Lots of beginners in wood pellet market prefer to make pellets with high thickness and also high firmness. Although they looks stunning, they will minimize the manufacturing and boost the abrasion.
