How to pick suitable wood pellet fuel for your boiler?<br>
Wood pellet fuels are constructed from sawdust or plant wastes. By pushing as well as molding, they end up being solid strips with the thickness of 0.8-1.4 t/m3. Wood pellets fuel has the exact same energy density as medium coals. The burning effect has actually enhanced a lot compared with bulky products. Besides, wood pellet fuels are convenient to shop as well as transportation.



Which has higher cost efficiency?

The quality of biomass pellet fuel varies with the raw materials it is made. Usually, there are high quality sawdust pellets, usual wood pellets, bamboo pellets, peanut shell pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medicine deposit pellets, natural sludge pellets, etc. They have different rates, homes and also application areas and also target at certain clients.



For business as well as personal customers, it is not a good idea to pick premium sawdust pellets or low-price rice husk pellets at all times. You must pick the wood pellets with high expense performance and suits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a typical biomass pellet fuel It has reduced cost and substandard high quality than sawdust pellets. Besides, it has narrower application locations than sawdust pellets.



Excellent quality sawdust pellets can be used in huge stokerfeed boiler, taken care of grate boiler, burner, hot-blast cooktop, smelting furnace, etc. Although small fish feed machine price is more than rice husk pellets, sawdust pellets remains in terrific demand. In high seasons, the top quality wood pellet supply is in lack.



Which wood pellet boiler do you use?

For fixed grate boiler or tiny pellet heater, you ought to choose those without coking.

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

For heating system, the wood pellets ought to have high warmth worth and the unpredictable dividing rate is high.

For thermal oil boiler, the wood pellets must have low ash content without coking, and the warm worth and also the volatile dividing rate is high.

Stockerfeed cooktops have bigger adaptability to wood pellets. You must think about the heating price need, automated or hands-on slag gadget, flue gas warmth recuperation device, dust collector types as well as pick the most appropriate wood pellets.



Actions to choose ideal wood pellet fuel.

Based on years of my experience on biomass pellet fuel manufacturing and biomass boiler advertising and marketing, I end the complying with steps on how to choose appropriate wood pellet fuel.



Action 1: analyze your wood pellet stoves and boilers

Step 2: list your demand on the wood pellet fuel

Step 3: survey the wood pellet makes within 800 kilometres, as well as discover the properties of their wood pellet fuels

Tip 4: compare the result of step2 as well as step3, as well as figure out the suppliers that fulfill your needs


Step 5: work out the unit cost based upon the provided price provided by the wood pellet suppliers.

Choose 2 or 3 providers as well as designate the acquisition quantity proportionally. Bear in mind to authorize contracts to protect an adequate supply.

Notes:

As a mature wood pellet consumer, you must not just concentrate on the rate of pellets or the device cost of warmth worth, however focus on the unit expense of 1-ton heavy steam production, including the cost of fuel, labor, maintenance, and also slag treatment.



Take the after-sale service into factor to consider. Some wood pellets manufactures can supply boiler updating as well as team training solution.



Quality signs of wood pellet fuel

For common uses, wood pellets fuel needs to meet the adhering to specifications. The diameter is 6-12mm, the length is 2-4 times that of size, and the mass thickness is larger than 600kg/m3. The squashing rate is much less tan 1.5%-2.0%, the ash material is lower than 1.5%, the sulfur and also chlorine web content should be less than 0.07%, nitrogen content less than 0.5%, as well as the warmth value is more than 16MJ/kg.



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



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

Density is a crucial sign of wood pellet quality. In a lot of situations, the density of wood pellet fuel is between 1.1 and 1.3 t/m3. visit site will raise the cost of manufacturing. Besides, high density needs high compression proportion, hence enhancing the abrasion of molding dies as well as reducing their functioning life.



As a result, we suggest to constrain the wood pellet density in between 0.8 and also 1.1 t/m3. Several starters in wood pellet sector favor to make pellets with high density and high firmness. Although they looks beautiful, they will lower the manufacturing and also boost the abrasion.
