Just how to select ideal wood pellet fuel for your boiler?<br>
Richi machine fuels are constructed from sawdust or plant wastes. By pressing and also molding, they come to be solid strips with the thickness of 0.8-1.4 t/m3. Wood pellets fuel has the same power thickness as tool coals. The burning effect has actually enhanced a great deal compared with large products. Besides, wood pellet fuels are convenient to store as well as transport.



Which has higher expense performance?

The high quality of biomass pellet fuel varies with the raw products it is made. Normally, there are premium quality sawdust pellets, usual wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medicine residue pellets, organic sludge pellets, and so on. They have different costs, homes as well as application places and target at details customers.



For business and personal individuals, it is not smart to choose top quality sawdust pellets or low-price rice husk pellets constantly. You ought to pick the wood pellets with high expense performance and fits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a common biomass pellet fuel It has lower rate and also substandard quality than sawdust pellets. Besides, it has narrower application areas than sawdust pellets.



Premium 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 terrific need. In high periods, the excellent quality wood pellet supply is in scarcity.



Which wood pellet boiler do you use?

For repaired grate boiler or little pellet heater, you should select those without coking.

For hot-blast oven, the wood pellets ought to have reduced ash content and no coking.

For heating furnace, the wood pellets must have high warmth worth and the unstable separating rate is high.

For thermal oil boiler, the wood pellets must have reduced ash content without coking, as well as the warm value and also the unstable separating price is high.

Stockerfeed ovens have broader flexibility to wood pellets. You need to consider the home heating rate need, automatic or manual slag tool, flue gas heat recovery tool, dust collector kinds and also pick the most appropriate wood pellets.



Actions to pick ideal wood pellet fuel.

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



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

Action 2: list your requirement on the wood pellet fuel

Step 3: study the wood pellet makes within 800 km, as well as learn more about the properties of their wood pellet fuels

Step 4: contrast the outcome of step2 as well as step3, as well as find out the suppliers that satisfy your demands

Tip 5: exercise the unit cost based on the provided price provided by the wood pellet vendors.

Pick 2 or 3 providers and also designate the acquisition quantity proportionally. Bear in mind to authorize agreements to safeguard an appropriate supply.

Notes:

As a fully grown wood pellet consumer, you must not just focus on the cost of pellets or the device price of warmth worth, but focus on the unit price of 1-ton heavy steam production, consisting of the expense of fuel, labor, maintenance, and also slag treatment.




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



Quality indications of wood pellet fuel

For typical uses, wood pellets fuel needs to meet the following criteria. The size is 6-12mm, the length is 2-4 times that of diameter, as well as the mass thickness is larger than 600kg/m3. The crushing price is much less tan 1.5%-2.0%, the ash web content is lower than 1.5%, the sulfur and chlorine web content need to be less than 0.07%, nitrogen web content less than 0.5%, and also the heat value is higher than 16MJ/kg.



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



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

Density is an important indicator of wood pellet high quality. In most scenarios, the thickness of wood pellet fuel is in between 1.1 as well as 1.3 t/m3. High thickness will increase the expense of manufacturing. Besides, high density needs high compression proportion, therefore boosting the abrasion of molding dies and also shortening their working life.



As a result, we suggest to restrict the wood pellet density between 0.8 and 1.1 t/m3. Numerous beginners in wood pellet sector favor to make pellets with high density and high firmness. Although they looks stunning, they will certainly decrease the production and also enhance the abrasion.
