How to select appropriate wood pellet fuel for your boiler?<br>
Wood pellet fuels are made of sawdust or plant wastes. By pressing and also molding, they become 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 actually boosted a whole lot compared with large products. Besides, wood pellet fuels are convenient to shop and also transport.




Which has higher cost efficiency?

The quality of biomass pellet fuel differs with the raw products it is made. Usually, there are excellent quality sawdust pellets, typical wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medication residue pellets, natural sludge pellets, etc. They have different rates, residential properties as well as application areas as well as target at particular customers.



For business as well as individual users, it is not smart to pick top quality sawdust pellets or low-price rice husk pellets constantly. You need to pick the wood pellets with high price efficiency and also fits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a common biomass pellet fuel It has reduced rate and also inferior high 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, burner, hot-blast cooktop, smelting furnace, and so on. Although the price is greater than rice husk pellets, sawdust pellets remains in great need. In cpm pellet mill manual , the premium quality wood pellet supply remains in shortage.



Which wood pellet boiler do you make use of?


For repaired grate boiler or small pellet heater, you must pick those without coking.

For hot-blast oven, the wood pellets must have low ash material as well as no coking.

For heating heater, the wood pellets should have high warmth worth as well as the unpredictable separating rate is high.

For thermal oil boiler, the wood pellets must have low ash content without coking, and the warm value and also the unpredictable separating price is high.

Stockerfeed cooktops have larger flexibility to wood pellets. You need to consider the home heating price demand, automated or hand-operated slag tool, flue gas warm recuperation tool, dirt collection agency kinds and choose the most ideal wood pellets.



Actions to pick ideal wood pellet fuel.

Based upon years of my experience on biomass pellet fuel manufacturing as well as biomass boiler marketing, I end the following steps on exactly how to select suitable wood pellet fuel.



Action 1: examine your wood pellet ovens and also boilers

Step 2: listing your demand on the wood pellet fuel

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

Step 4: compare the outcome of step2 and also step3, and also figure out the vendors that fulfill your needs

Step 5: work out the unit cost based on the delivered rate supplied by the wood pellet vendors.

Select 2 or 3 distributors and designate the purchase amount proportionally. Bear in mind to authorize agreements to safeguard an appropriate supply.

Notes:

As a fully grown wood pellet customer, you should not only concentrate on the rate of pellets or the unit price of warm worth, but take notice of the device price of 1-ton vapor production, consisting of the expense of fuel, labor, maintenance, and slag treatment.



Take the after-sale service into consideration. Some wood pellets manufactures can provide boiler updating as well as team training service.



Quality indicators of wood pellet fuel

For common uses, wood pellets fuel has to fulfill the adhering to parameters. The diameter is 6-12mm, the size is 2-4 times that of diameter, and also the mass density is larger than 600kg/m3. The squashing rate is less tan 1.5%-2.0%, the ash content is less than 1.5%, the sulfur and also chlorine content must be less than 0.07%, nitrogen content less than 0.5%, and also the warmth worth is greater than 16MJ/kg.



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



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

Thickness is an important indicator 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 density will increase the expense of manufacturing. Besides, biomass pellet mill calls for high compression proportion, hence increasing the abrasion of molding dies and shortening their working life.



As a result, we recommend to restrict the wood pellet thickness between 0.8 and 1.1 t/m3. Numerous starters in wood pellet industry choose to make pellets with high thickness and also high firmness. Although they looks stunning, they will lower the manufacturing as well as enhance the abrasion.
