Exactly how to select appropriate wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or plant 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 tool coals. The burning effect has improved a lot compared with large materials. Besides, wood pellet fuels are convenient to store and also transportation.



Which has greater price efficiency?

The top quality of biomass pellet fuel varies with the raw materials it is made. Usually, there are premium quality sawdust pellets, common wood pellets, bamboo pellets, peanut shell pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medication residue pellets, organic sludge pellets, and so on. They have different costs, properties and application areas and also target at specific consumers.



For enterprise and personal individuals, it is not important to choose high-grade sawdust pellets or low-price rice husk pellets all the time. You should select the wood pellets with high cost efficiency and suits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a common biomass pellet fuel It has lower rate as well as substandard high quality than sawdust pellets. Besides, it has narrower application locations than sawdust pellets.



Excellent quality sawdust pellets can be applied in huge stokerfeed boiler, fixed grate boiler, heater, hot-blast oven, smelting heater, and so on. Although richi pellet is higher than rice husk pellets, sawdust pellets is in terrific need. In high periods, the premium quality wood pellet supply remains in lack.



Which wood pellet boiler do you use?

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

For hot-blast cooktop, the wood pellets need to have reduced ash web content as well as no coking.

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

For thermal oil boiler, the wood pellets should have reduced ash web content without coking, and also the warmth worth and the volatile dividing price is high.

Stockerfeed cooktops have wider flexibility to wood pellets. You must think about the heating price need, automatic or hands-on slag gadget, flue gas warm recuperation gadget, dirt collection agency kinds and select one of the most suitable wood pellets.



Actions to choose ideal wood pellet fuel.

Based on years of my experience on biomass pellet fuel manufacturing and also biomass boiler marketing, I wrap up the adhering to steps on just how to select suitable wood pellet fuel.



Step 1: analyze your wood pellet cooktops and also boilers

Action 2: listing your need on the wood pellet fuel

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

Tip 4: contrast the outcome of step2 as well as step3, and also figure out the providers that satisfy your needs

Tip 5: exercise the unit cost based on the provided cost supplied by the wood pellet distributors.

Pick 2 or 3 providers and also assign the purchase amount proportionally. Bear in mind to authorize agreements to protect an ample supply.

Notes:

As a fully grown wood pellet customer, you should not just concentrate on the price of pellets or the system price of warm worth, but focus on the device expense of 1-ton heavy steam production, including the price of fuel, labor, upkeep, as well as slag treatment.



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



Quality indications of wood pellet fuel

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



For commercial objective, wood pellets normally have the diameter of 8-10mm as well as the length of 25-35mm.




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

Density is a vital indication of wood pellet top quality. In the majority of situations, the thickness of wood pellet fuel is between 1.1 as well as 1.3 t/m3. High thickness will certainly enhance the cost of production. Besides, richi pellet needs high compression ratio, thus boosting the abrasion of molding dies and reducing their working life.



For that reason, we advise to confine the wood pellet density in between 0.8 as well as 1.1 t/m3. Lots of beginners in wood pellet industry choose to make pellets with high thickness and also high solidity. Although they looks attractive, they will minimize the manufacturing as well as enhance the abrasion.
