Exactly how to select appropriate wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or plant wastes. By pushing and also molding, they become solid strips with the density of 0.8-1.4 t/m3. fish feed making machine low price has the same power density as tool coals. The burning effect has boosted a whole lot compared with large materials. Besides, wood pellet fuels are convenient to store as well as transport.



Which has greater price performance?

The top quality of biomass pellet fuel differs with the raw materials it is made. Usually, there are excellent quality sawdust pellets, common wood pellets, bamboo pellets, peanut shell pellets, rice husk pellets, maize stalk pellets, pet dung pellets, sugar or medication residue pellets, natural sludge pellets, etc. They have various prices, properties as well as application areas as well as target at particular customers.




For venture as well as individual individuals, it is not smart to choose top notch sawdust pellets or low-price rice husk pellets all the time. You need to select the wood pellets with high expense performance and also fits your biomass boiler.



Rice husk pellets vs sawdust pellets

Rice husk pellets is a common biomass pellet fuel It has lower rate and inferior quality than sawdust pellets. Besides, it has narrower application areas than sawdust pellets.



Top quality sawdust pellets can be applied in big stokerfeed boiler, repaired grate boiler, heater, hot-blast stove, smelting heating system, and so on. Although wood pellet extruder is greater than rice husk pellets, sawdust pellets is in wonderful need. In high periods, the premium quality wood pellet supply remains in shortage.



Which wood pellet boiler do you use?

For taken care of grate boiler or small pellet burner, you need to select those without coking.

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

For smelting furnace, the wood pellets should have high heat value and the unstable separating price is high.

For thermal oil boiler, the wood pellets ought to have reduced ash web content without coking, and the warmth worth and the volatile separating rate is high.

Stockerfeed stoves have bigger flexibility to wood pellets. You must consider the heating price demand, automatic or hands-on slag device, flue gas warmth recovery tool, dust collection agency types and select one of the most suitable wood pellets.



Actions to pick suitable wood pellet fuel.

Based on years of my experience on biomass pellet fuel manufacturing and also biomass boiler advertising and marketing, I conclude the following steps on just how to pick appropriate wood pellet fuel.



Action 1: analyze your wood pellet ovens and boilers

Action 2: list your demand on the wood pellet fuel

Action 3: study the wood pellet makes within 800 kilometres, and discover the residential properties of their wood pellet fuels

Step 4: compare the outcome of step2 and step3, and discover the distributors that meet your requirements

Tip 5: exercise the unit cost based on the supplied price provided by the wood pellet providers.

Pick 2 or 3 providers as well as allocate the acquisition amount proportionally. Remember to authorize contracts to secure a sufficient supply.

Notes:

As a mature wood pellet customer, you need to not only focus on the rate of pellets or the unit expense of warmth value, yet focus on the unit expense of 1-ton heavy steam manufacturing, including the cost of fuel, labor, maintenance, and also slag treatment.



Take the after-sale service into factor to consider. Some wood pellets produces can offer boiler upgrading and also personnel training solution.



Quality indicators of wood pellet fuel

For common usages, wood pellets fuel has to meet the complying with specifications. The size is 6-12mm, the length is 2-4 times that of size, as well as the bulk thickness is larger than 600kg/m3. The crushing rate is less tan 1.5%-2.0%, the ash material is lower than 1.5%, the sulfur and chlorine content should be less than 0.07%, nitrogen material less than 0.5%, and also the heat worth is higher than 16MJ/kg.



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



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

Density is a crucial indicator of wood pellet high quality. In the majority of circumstances, the density of wood pellet fuel is in between 1.1 as well as 1.3 t/m3. High density will certainly increase the expense of production. Besides, high thickness calls for high compression proportion, therefore enhancing the abrasion of molding dies as well as reducing their working life.




Therefore, we recommend to confine the wood pellet thickness between 0.8 and also 1.1 t/m3. Many starters in wood pellet market choose to make pellets with high thickness and high solidity. Although they looks attractive, they will certainly minimize the manufacturing and boost the abrasion.
