How to pick suitable wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or crop wastes. By pushing as well as molding, they end up being solid strips with the thickness of 0.8-1.4 t/m3. hemp pellet mill has the very same energy density as tool coals. The burning impact has boosted a lot compared with large products. Besides, wood pellet fuels are convenient to store as well as transport.



Which has higher expense efficiency?

The high quality of biomass pellet fuel differs with the raw products it is made. Usually, there are premium quality sawdust pellets, common wood pellets, bamboo pellets, peanut shell pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medicine residue pellets, organic sludge pellets, and so on. They have various costs, homes and also application places and target at certain customers.



For business and also individual customers, it is not important to choose top notch sawdust pellets or low-price rice husk pellets at all times. You ought to pick the wood pellets with high cost efficiency as well as suits your biomass boiler.



Rice husk pellets vs sawdust pellets

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



Premium quality sawdust pellets can be applied in huge stokerfeed boiler, fixed grate boiler, heater, hot-blast cooktop, smelting heater, etc. Although the rate is more than rice husk pellets, sawdust pellets is in terrific need. In high seasons, the top quality wood pellet supply is in shortage.



Which wood pellet boiler do you make use of?

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

For hot-blast cooktop, the wood pellets ought to have low ash content as well as no coking.

For smelting furnace, the wood pellets must have high warm worth and the unpredictable separating price is high.

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

Stockerfeed ranges have broader versatility to wood pellets. pellet grinder machine need to take into consideration the heating rate need, automated or manual slag gadget, flue gas heat recovery device, dust enthusiast types as well as pick one of the most appropriate wood pellets.




Steps to select suitable wood pellet fuel.

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



Action 1: examine your wood pellet cooktops and boilers

Action 2: listing your need on the wood pellet fuel

Step 3: survey the wood pellet makes within 800 km, and also learn more about the properties of their wood pellet fuels

Step 4: compare the result of step2 and step3, as well as learn the providers that satisfy your needs

Step 5: work out the unit expense based upon the supplied price provided by the wood pellet vendors.

Choose 2 or 3 vendors and also assign the purchase amount proportionally. Bear in mind to sign contracts to safeguard an ample supply.

Notes:

As a fully grown wood pellet consumer, you need to not just focus on the rate of pellets or the device price of warmth worth, yet take notice of the unit cost of 1-ton steam manufacturing, including the expense of fuel, labor, upkeep, and slag treatment.



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




Quality indications of wood pellet fuel

For common usages, wood pellets fuel has to satisfy the adhering to specifications. The diameter is 6-12mm, the size is 2-4 times that of size, and the bulk thickness is larger than 600kg/m3. The crushing rate is much less tan 1.5%-2.0%, the ash content is lower than 1.5%, the sulfur and also chlorine content ought to be less than 0.07%, nitrogen web content less than 0.5%, as well as the heat value is higher than 16MJ/kg.



For industrial objective, wood pellets usually have the size of 8-10mm as well as the length of 25-35mm.



What's the best thickness for making wood pellets?

Thickness is a crucial indicator of wood pellet quality. In many circumstances, the density of wood pellet fuel is between 1.1 and also 1.3 t/m3. High thickness will boost the cost of manufacturing. Besides, high density calls for high compression proportion, therefore raising the abrasion of molding dies as well as reducing their functioning life.



Consequently, we recommend to restrict the wood pellet thickness in between 0.8 and 1.1 t/m3. Lots of beginners in wood pellet industry like to make pellets with high density and high solidity. Although they looks attractive, they will reduce the manufacturing and raise the abrasion.
