How to pick ideal wood pellet fuel for your boiler?<br>
Wood pellet fuels are made of sawdust or plant wastes. By pushing as well as molding, they become strong strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the very same power density as medium coals. The burning impact has actually enhanced a whole lot compared to bulky products. Besides, wood pellet fuels are convenient to shop and transport.



Which has higher expense efficiency?

The quality of biomass pellet fuel varies with the raw materials it is made. Generally, there are excellent quality sawdust pellets, typical wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medicine deposit pellets, natural sludge pellets, etc. They have various rates, properties as well as application locations and target at specific consumers.



For business as well as personal users, it is not wise to pick premium sawdust pellets or low-price rice husk pellets regularly. You must pick the wood pellets with high price performance as well as matches your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a typical biomass pellet fuel It has lower rate as well as substandard high quality than sawdust pellets. Besides, animal feed making machine price has narrower application locations than sawdust pellets.



Excellent quality sawdust pellets can be applied in huge stokerfeed boiler, taken care of grate boiler, burner, hot-blast stove, smelting heating system, and so on. Although the cost is more than rice husk pellets, sawdust pellets is in great need. In high periods, the premium quality wood pellet supply remains in scarcity.



Which wood pellet boiler do you utilize?

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

For hot-blast cooktop, the wood pellets should have low ash material as well as no coking.

For smelting heating system, the wood pellets ought to have high heat worth and the unstable dividing price is high.

For thermal oil boiler, the wood pellets need to have reduced ash web content without coking, as well as the heat value and the unstable dividing rate is high.


Stockerfeed stoves have wider flexibility to wood pellets. You need to take into consideration the heating price need, automated or manual slag gadget, flue gas heat recuperation tool, dust enthusiast kinds as well as choose one of the most appropriate wood pellets.



Actions to select appropriate wood pellet fuel.

Based on years of my experience on biomass pellet fuel production and biomass boiler advertising and marketing, I conclude the adhering to steps on exactly how to pick ideal wood pellet fuel.



Action 1: examine your wood pellet stoves and boilers

Action 2: list your requirement on the wood pellet fuel

Step 3: survey the wood pellet manufactures within 800 kilometres, as well as learn more about the homes of their wood pellet fuels

Step 4: compare the result of step2 and also step3, and learn the vendors that meet your requirements

Step 5: work out the unit expense based on the supplied cost supplied by the wood pellet suppliers.

Choose 2 or 3 distributors and assign the acquisition quantity proportionally. Keep in mind to authorize contracts to protect an adequate supply.

Notes:

As a fully grown wood pellet consumer, you need to not just focus on the cost of pellets or the system cost of warm value, but take note of the device expense of 1-ton heavy steam production, consisting of the expense of fuel, labor, maintenance, and slag treatment.



Take the after-sale service into factor to consider. richi pellet can supply boiler updating as well as personnel training service.



Quality indicators of wood pellet fuel

For common usages, wood pellets fuel needs to meet the following parameters. The size is 6-12mm, the size is 2-4 times that of size, as well as 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 chlorine web content ought to be less than 0.07%, nitrogen material less than 0.5%, and also the warm worth is higher than 16MJ/kg.



For commercial function, wood pellets generally have the size of 8-10mm as well as the size of 25-35mm.



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

Density is a vital sign of wood pellet top quality. In most circumstances, the thickness of wood pellet fuel is between 1.1 and 1.3 t/m3. High thickness will certainly raise the cost of manufacturing. Besides, high density needs high compression ratio, hence raising the abrasion of molding dies and also reducing their functioning life.



Consequently, we advise to confine the wood pellet density between 0.8 and 1.1 t/m3. Lots of starters in wood pellet industry choose to make pellets with high thickness as well as high solidity. Although they looks stunning, they will reduce the production and boost the abrasion.
