How to choose ideal wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or plant wastes. By pushing and molding, they end up being solid strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the exact same power density as medium coals. The burning effect has actually boosted a lot compared to cumbersome materials. Besides, wood pellet fuels are convenient to shop and transportation.



Which has greater expense efficiency?

The quality of biomass pellet fuel varies with the raw materials it is made. Usually, there are top quality sawdust pellets, usual wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medication deposit pellets, natural sludge pellets, etc. They have different rates, residential properties and application locations and target at certain consumers.



For enterprise and also personal customers, it is not important to select top notch sawdust pellets or low-price rice husk pellets all the time. chicken feed machine must select the wood pellets with high expense efficiency and also matches your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a typical biomass pellet fuel It has reduced rate as well as substandard top quality than sawdust pellets. Besides, it 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 cooktop, smelting furnace, etc. Although the rate is higher than rice husk pellets, sawdust pellets is in wonderful demand. In wood pellet production line , the premium quality wood pellet supply is in scarcity.



Which wood pellet boiler do you utilize?

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

For hot-blast oven, the wood pellets need to have reduced ash web content as well as no coking.

For heating heater, the wood pellets ought to have high warmth worth and the volatile separating price is high.

For thermal oil boiler, the wood pellets should have low ash web content without coking, and also the warmth worth and the unstable separating price is high.

Stockerfeed ovens have broader versatility to wood pellets. You should think about the heating price need, automated or manual slag gadget, flue gas heat recovery device, dust collector kinds and also choose the most suitable wood pellets.



Steps to select appropriate wood pellet fuel.

Based upon years of my experience on biomass pellet fuel manufacturing and also biomass boiler advertising, I conclude the following steps on how to select ideal wood pellet fuel.




Step 1: evaluate your wood pellet cooktops and boilers

Step 2: listing your requirement on the wood pellet fuel

Step 3: study the wood pellet produces within 800 kilometres, and discover the properties of their wood pellet fuels

Step 4: compare the result of step2 as well as step3, and also find out the suppliers that satisfy your needs

Step 5: exercise the unit cost based on the delivered price offered by the wood pellet providers.

Choose 2 or 3 providers and designate the acquisition quantity proportionally. Bear in mind to sign agreements to protect an ample supply.

Notes:

As a fully grown wood pellet consumer, you need to not only focus on the rate of pellets or the unit expense of warm value, but pay attention to the unit cost of 1-ton heavy steam manufacturing, consisting of the price of fuel, labor, upkeep, and also slag therapy.



Take the after-sale service right into factor to consider. Some wood pellets produces can offer boiler updating and also team training service.



Quality signs of wood pellet fuel

For usual uses, wood pellets fuel has to fulfill the complying with parameters. The diameter is 6-12mm, the size is 2-4 times that of size, and also the bulk density is larger than 600kg/m3. The crushing rate is much less tan 1.5%-2.0%, the ash content is lower than 1.5%, the sulfur and also chlorine web content must be less than 0.07%, nitrogen web content less than 0.5%, and also the warmth worth is more than 16MJ/kg.



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



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

Density is an essential indication of wood pellet top quality. In the majority of situations, the thickness of wood pellet fuel is between 1.1 as well as 1.3 t/m3. High thickness will certainly increase the price of manufacturing. Besides, high density requires high compression ratio, hence raising the abrasion of molding dies and shortening their functioning life.




Consequently, we recommend to confine the wood pellet density between 0.8 and also 1.1 t/m3. Lots of starters in wood pellet sector like to make pellets with high thickness and high hardness. Although they looks attractive, they will minimize the manufacturing and increase the abrasion.
