How to pick suitable wood pellet fuel for your boiler?<br>
Wood pellet fuels are made of sawdust or crop wastes. By pressing and 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 density as tool coals. The burning impact has actually enhanced a whole lot compared to cumbersome materials. Besides, wood pellet fuels are convenient to store as well as transportation.



Which has higher expense performance?

The quality of biomass pellet fuel differs with the raw materials it is made. Generally, there are premium quality sawdust pellets, common wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medicine residue pellets, natural sludge pellets, etc. They have different rates, homes and also application locations as well as target at specific customers.



For enterprise and individual customers, it is not wise to pick high-quality sawdust pellets or low-price rice husk pellets all the time. Visit This Link should choose the wood pellets with high price performance as well as fits your biomass boiler.



Rice husk pellets vs sawdust pellets

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



High quality sawdust pellets can be applied in huge stokerfeed boiler, dealt with grate boiler, burner, hot-blast range, smelting heating system, etc. Although the rate is more than rice husk pellets, sawdust pellets is in great need. In high periods, the top quality wood pellet supply is in lack.



Which wood pellet boiler do you utilize?

For fixed grate boiler or tiny pellet burner, you need to select those without coking.

For hot-blast range, the wood pellets must have low ash content and no coking.

For heating furnace, the wood pellets must have high heat worth and also the unstable separating price is high.

For thermal oil boiler, the wood pellets ought to have reduced ash content without coking, and also the warmth value and the volatile dividing price is high.


Stockerfeed stoves have broader adaptability to wood pellets. You need to think about the home heating rate demand, automatic or hands-on slag device, flue gas warmth healing tool, dirt enthusiast kinds as well as choose the most ideal wood pellets.



Steps to pick suitable wood pellet fuel.

Based upon years of my experience on biomass pellet fuel manufacturing and also biomass boiler marketing, I end the adhering to steps on exactly how to pick ideal wood pellet fuel.



Action 1: assess your wood pellet ranges and boilers

Action 2: checklist your demand on the wood pellet fuel

Step 3: study the wood pellet manufactures within 800 kilometres, and also learn more about the residential or commercial properties of their wood pellet fuels

Step 4: compare the outcome of step2 as well as step3, and figure out the vendors that satisfy your demands

Step 5: exercise the unit cost based upon the supplied cost supplied by the wood pellet suppliers.

Select 2 or 3 vendors and allocate the purchase amount proportionally. Bear in mind to authorize contracts to secure an ample supply.

Notes:

As a fully grown wood pellet consumer, you should not only concentrate on the rate of pellets or the system expense of heat value, yet take notice of the unit cost of 1-ton heavy steam manufacturing, consisting of the expense of fuel, labor, upkeep, and slag treatment.



Take the after-sale service into factor to consider. Some wood pellets makes can supply boiler upgrading and team training solution.



Quality indications of wood pellet fuel

For typical usages, wood pellets fuel needs to satisfy the complying with specifications. The size is 6-12mm, the size is 2-4 times that of diameter, and also the mass thickness is larger than 600kg/m3. The squashing price is much less tan 1.5%-2.0%, the ash content is less than 1.5%, the sulfur and also chlorine content ought to be less than 0.07%, nitrogen web content less than 0.5%, and the heat worth is higher than 16MJ/kg.



For industrial purpose, wood pellets normally have the size of 8-10mm as well as the size of 25-35mm.



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

Thickness is an essential indicator of wood pellet quality. In most scenarios, the thickness of wood pellet fuel is in between 1.1 and also 1.3 t/m3. High density will certainly increase the cost of manufacturing. Besides, high thickness requires high compression proportion, therefore boosting the abrasion of molding dies as well as reducing their functioning life.



For that reason, we suggest to constrain the wood pellet density between 0.8 as well as 1.1 t/m3. https://www.linkedin.com/pulse/frequently-asked-question-from-consumers-who-buy-timber-carmen-huang in wood pellet sector favor to make pellets with high density as well as high solidity. Although they looks beautiful, they will minimize the production and also enhance the abrasion.
