How to choose suitable wood pellet fuel for your boiler
How to choose ideal wood pellet fuel for your boiler?
Wood pellet fuels are made of sawdust or plant wastes. By pushing and also molding, they become solid strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the same energy density as medium coals. The burning result has actually improved a whole lot compared to large materials. Besides, wood pellet fuels are convenient to shop as well as transportation.

Which has higher price efficiency?
The top quality of biomass pellet fuel differs with the raw materials it is made. Typically, 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, buildings as well as application places and target at certain customers.

For venture and personal customers, it is not wise to pick top notch sawdust pellets or low-price rice husk pellets regularly. You must pick the wood pellets with high price performance 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 substandard high quality than sawdust pellets. Besides, it has narrower application areas than sawdust pellets.


Excellent quality sawdust pellets can be used in large stokerfeed boiler, dealt with grate boiler, burner, hot-blast cooktop, smelting furnace, etc. Although the cost is more than rice husk pellets, sawdust pellets remains in excellent need. In high periods, the excellent quality wood pellet supply is in lack.

Which wood pellet boiler do you use?
For dealt with grate boiler or small pellet burner, you must select those without coking.
For hot-blast range, the wood pellets must have reduced ash content as well as no coking.
For heating furnace, the wood pellets need to have high warmth value and also the volatile separating rate is high.
For thermal oil boiler, the wood pellets should have reduced ash material without coking, and the heat value as well as the volatile dividing price is high.
Stockerfeed ovens have larger flexibility to wood pellets. pellet extruder machine ought to think about the home heating rate need, automatic or manual slag device, flue gas warmth recovery device, dust enthusiast kinds and also select the most appropriate wood pellets.

Actions to select appropriate wood pellet fuel.
Based upon years of my experience on biomass pellet fuel production as well as biomass boiler advertising, I end the complying with steps on exactly how to choose ideal wood pellet fuel.


Action 1: examine your wood pellet cooktops and boilers
Step 2: list your requirement on the wood pellet fuel
Action 3: study the wood pellet manufactures within 800 kilometres, and learn about the residential properties of their wood pellet fuels
Step 4: compare the result of step2 and also step3, and also find out the suppliers that meet your demands
Tip 5: work out the system price based upon the provided rate given by the wood pellet vendors.
Select 2 or 3 distributors and assign the purchase quantity proportionally. Keep in mind to authorize agreements to protect an ample supply.
Notes:
As a fully grown wood pellet customer, you must not only concentrate on the cost of pellets or the unit cost of warmth worth, however focus on the system expense of 1-ton steam manufacturing, including the price of fuel, labor, upkeep, and also slag therapy.

Take the after-sale solution right into factor to consider. Some wood pellets makes can give boiler updating and personnel training solution.

Quality indications of wood pellet fuel
For typical uses, wood pellets fuel has to satisfy the complying with specifications. The size is 6-12mm, the length is 2-4 times that of diameter, as well as the bulk 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 as well as chlorine material should be less than 0.07%, nitrogen material less than 0.5%, and the warm worth is greater than 16MJ/kg.

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

What's the very best density for making wood pellets?
Density is a vital sign of wood pellet top quality. In many situations, the density of wood pellet fuel is between 1.1 and also 1.3 t/m3. High density will enhance the expense of production. Besides, high thickness calls for high compression ratio, thus enhancing the abrasion of molding dies and also shortening their functioning life.

Therefore, we suggest to restrict the wood pellet thickness between 0.8 and also 1.1 t/m3. mini pellet machine in wood pellet sector favor to make pellets with high density as well as high firmness. Although they looks beautiful, they will reduce the production and raise the abrasion.
