Just how to choose appropriate wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or plant wastes. By pushing and also molding, they come to be solid strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the exact same energy density as tool coals. The burning impact has boosted a lot compared to cumbersome products. Besides, wood pellet fuels are convenient to store and transport.



Which has higher cost efficiency?

The top quality of biomass pellet fuel differs with the raw materials it is made. Usually, there are high quality sawdust pellets, usual wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medicine deposit pellets, organic sludge pellets, etc. They have different rates, residential properties and also application areas as well as target at specific clients.



For enterprise and also individual customers, it is not wise to choose premium sawdust pellets or low-price rice husk pellets at all times. You ought to choose the wood pellets with high expense efficiency as well as fits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is an usual biomass pellet fuel It has lower rate and substandard top quality than sawdust pellets. Besides, it has narrower application locations than sawdust pellets.




Top quality sawdust pellets can be used in big stokerfeed boiler, dealt with grate boiler, heater, hot-blast range, smelting heater, etc. Although the cost is more than rice husk pellets, sawdust pellets is in terrific demand. In high periods, the excellent quality wood pellet supply is in scarcity.



Which wood pellet boiler do you utilize?

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


For hot-blast oven, the wood pellets need to have low ash content and also no coking.

For heating system, the wood pellets need to have high heat value and also the unstable dividing rate is high.

For thermal oil boiler, the wood pellets need to have low ash web content without coking, and also the warm worth and the volatile dividing price is high.

Stockerfeed stoves have broader versatility to wood pellets. You must take into consideration the heating price demand, automated or hands-on slag tool, flue gas warm recuperation gadget, dust collector types and pick the most suitable wood pellets.



Steps to select ideal wood pellet fuel.

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



Action 1: analyze your wood pellet ranges and boilers

Action 2: listing your need on the wood pellet fuel

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

Tip 4: contrast the result of step2 as well as step3, and also find out the providers that fulfill your needs

Step 5: work out the unit price based on the delivered rate provided by the wood pellet distributors.

Pick 2 or 3 providers and also designate the purchase amount proportionally. rice husk pellet machine in mind to sign agreements to protect an ample supply.

Notes:

As a mature wood pellet consumer, you must not just focus on the cost of pellets or the unit cost of warmth worth, however take note of the system expense of 1-ton steam manufacturing, including the price of fuel, labor, maintenance, and slag treatment.



Take the after-sale solution right into consideration. Some wood pellets manufactures can offer boiler updating and staff training solution.



Quality signs of wood pellet fuel

For usual usages, wood pellets fuel has to fulfill the complying with criteria. The size is 6-12mm, the length is 2-4 times that of size, and the bulk density is larger than 600kg/m3. The crushing rate 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 content less than 0.5%, and also the warmth value is higher than 16MJ/kg.



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



What's the best thickness for making wood pellets?

Density is an important indicator of wood pellet top quality. In many situations, the thickness of wood pellet fuel is between 1.1 and also 1.3 t/m3. High thickness will raise the expense of production. Besides, high thickness calls for high compression ratio, therefore increasing the abrasion of molding dies and reducing their working life.



Consequently, we advise to confine the wood pellet density in between 0.8 and also 1.1 t/m3. Lots of beginners in wood pellet market prefer to make pellets with high density and also high firmness. Although cattle feed pellet making machine looks stunning, they will certainly lower the manufacturing as well as enhance the abrasion.
