Just how to pick ideal wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or crop wastes. By pushing and also molding, they end up being strong strips with the thickness of 0.8-1.4 t/m3. Richi machinery has the same power thickness as medium coals. The burning effect has actually improved a whole lot compared to bulky materials. Besides, wood pellet fuels are convenient to store and also transport.



Which has greater expense efficiency?

The top quality of biomass pellet fuel differs with the raw materials it is made. Generally, there are top quality sawdust pellets, common wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medication residue pellets, organic sludge pellets, and so on. They have different rates, residential or commercial properties as well as application areas and also target at details customers.



For enterprise and also individual customers, it is not important to choose high-grade sawdust pellets or low-price rice husk pellets at all times. You must choose the wood pellets with high cost efficiency and fits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is an usual biomass pellet fuel It has lower cost and substandard quality than sawdust pellets. Besides, lucerne pellet mill has narrower application locations than sawdust pellets.



High quality sawdust pellets can be applied in big stokerfeed boiler, dealt with grate boiler, burner, hot-blast stove, smelting heater, and so on. Although the rate is more than rice husk pellets, sawdust pellets is in wonderful demand. In high periods, the top quality wood pellet supply is in lack.



Which wood pellet boiler do you make use of?

For taken care of grate boiler or tiny pellet heater, you should select those without coking.

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

For heating system, the wood pellets need to have high heat value and also the unpredictable separating price is high.

For thermal oil boiler, the wood pellets must have low ash content without coking, as well as the warm value and the unpredictable dividing rate is high.

Stockerfeed stoves have bigger flexibility to wood pellets. You ought to think about the heating price demand, automated or hands-on slag tool, flue gas warm healing device, dirt collector kinds as well as select the most ideal wood pellets.



Actions to choose ideal wood pellet fuel.

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




Action 1: assess your wood pellet ovens and also boilers

Step 2: checklist your requirement on the wood pellet fuel

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

Tip 4: compare the outcome of step2 and also step3, and learn the providers that satisfy your requirements

Tip 5: exercise the device cost based upon the delivered rate given by the wood pellet suppliers.

Choose 2 or 3 suppliers as well as allot the purchase amount proportionally. Keep in mind to authorize contracts to safeguard a sufficient supply.

Notes:

As a mature wood pellet consumer, you need to not only concentrate on the price of pellets or the device price of warmth value, however take notice of the device cost of 1-ton steam production, including the expense of fuel, labor, upkeep, as well as slag treatment.



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



Quality signs of wood pellet fuel

For usual uses, wood pellets fuel has to fulfill the following specifications. 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 crushing price is less tan 1.5%-2.0%, the ash web content is less than 1.5%, the sulfur as well as chlorine content need to be less than 0.07%, nitrogen material less than 0.5%, as well as the warm worth is more than 16MJ/kg.



For commercial function, wood pellets typically have the diameter of 8-10mm as well as the length of 25-35mm.



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

Thickness is an essential indicator of wood pellet top quality. In many circumstances, the density of wood pellet fuel is between 1.1 and also 1.3 t/m3. High density will certainly boost the expense of production. Besides, high thickness needs high compression proportion, hence raising the abrasion of molding dies as well as reducing their working life.



Consequently, we advise to constrain the wood pellet density between 0.8 and 1.1 t/m3. Several starters in wood pellet sector like to make pellets with high thickness and also high firmness. Although they looks attractive, they will certainly lower the production as well as raise the abrasion.
