How to choose suitable wood pellet fuel for your boiler?<br>
Wood pellet fuels are made of sawdust or plant wastes. By pressing and molding, they come to be solid strips with the thickness of 0.8-1.4 t/m3. Wood pellets fuel has the very same energy density as tool coals. The burning effect has actually enhanced a lot compared with cumbersome materials. Besides, wood pellet fuels are convenient to store and also transportation.



Which has greater price performance?

The top quality of biomass pellet fuel varies with the raw products it is made. Usually, there are excellent quality sawdust pellets, common wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medicine residue pellets, natural sludge pellets, and so on. They have different rates, residential or commercial properties as well as application areas as well as target at specific consumers.



For enterprise and individual users, it is not a good idea to pick top notch sawdust pellets or low-price rice husk pellets at all times. You must pick the wood pellets with high cost efficiency and fits your biomass boiler.



Rice husk pellets vs sawdust pellets

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



Premium quality sawdust pellets can be applied in huge stokerfeed boiler, taken care of grate boiler, heater, hot-blast range, smelting heater, and so on. Although the cost is more than rice husk pellets, sawdust pellets remains in excellent demand. In high seasons, the high quality wood pellet supply remains in scarcity.



Which wood pellet boiler do you utilize?

For repaired grate boiler or small pellet burner, you should choose those without coking.

For hot-blast range, the wood pellets ought to have reduced ash content and also no coking.

For heating furnace, the wood pellets ought to have high warmth worth and the unpredictable separating rate is high.

For thermal oil boiler, the wood pellets need to have low ash content without coking, and also the warmth value and the unstable separating price is high.

Stockerfeed ranges have larger flexibility to wood pellets. You ought to take into consideration the heating rate need, automated or hand-operated slag gadget, flue gas warmth recovery gadget, dust enthusiast kinds and also choose one of the most appropriate wood pellets.



Actions to pick ideal wood pellet fuel.

Based on years of my experience on biomass pellet fuel production as well as biomass boiler advertising and marketing, I end the complying with steps on exactly how to select suitable wood pellet fuel.



Step 1: assess your wood pellet ovens and boilers

Action 2: checklist your requirement on the wood pellet fuel

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

Step 4: contrast the outcome of step2 and also step3, as well as learn the distributors that fulfill your needs

Tip 5: work out the device price based on the provided price given by the wood pellet distributors.


Pick 2 or 3 suppliers and designate the purchase amount proportionally. Keep in mind to authorize contracts to safeguard an adequate supply.

Notes:

As a fully grown wood pellet customer, you must not only focus on the rate of pellets or the unit expense of warm value, yet take notice of the system cost of 1-ton vapor manufacturing, consisting of the expense of fuel, labor, upkeep, and slag therapy.




Take the after-sale solution right into factor to consider. Some wood pellets produces can provide boiler updating as well as personnel training service.



Quality indications of wood pellet fuel

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



For industrial objective, wood pellets normally have the size of 8-10mm and the length of 25-35mm.



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

Thickness is a vital sign of wood pellet quality. In most scenarios, the thickness of wood pellet fuel is between 1.1 and 1.3 t/m3. High thickness will certainly enhance the cost of production. Besides, high density needs high compression proportion, therefore raising the abrasion of molding dies and shortening their functioning life.



Consequently, we advise to restrict the wood pellet thickness in between 0.8 as well as 1.1 t/m3. richi pellet mill in wood pellet industry like to make pellets with high thickness as well as high solidity. Although they looks beautiful, they will certainly minimize the production and also increase the abrasion.
