How to select appropriate wood pellet fuel for your boiler?<br>
Wood pellet fuels are made from sawdust or crop wastes. By pushing as well as molding, they become strong strips with the thickness of 0.8-1.4 t/m3. Wood pellets fuel has the same energy density as tool coals. The burning impact has improved a lot compared to large materials. Besides, wood pellet fuels are convenient to shop and transportation.



Which has higher price performance?

The high quality of biomass pellet fuel varies with the raw products it is made. Typically, there are paper pellet making machine , 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 different prices, residential or commercial properties and application locations as well as target at details customers.



For venture and also personal users, it is not wise to pick premium sawdust pellets or low-price rice husk pellets all the time. You ought to select the wood pellets with high cost efficiency and also suits your biomass boiler.



Rice husk pellets vs sawdust pellets

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



Premium quality sawdust pellets can be used in huge stokerfeed boiler, repaired grate boiler, heater, hot-blast cooktop, smelting heater, etc. Although the rate is more than rice husk pellets, sawdust pellets remains in terrific demand. In high seasons, the high quality wood pellet supply remains in scarcity.



Which wood pellet boiler do you make use of?

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

For hot-blast cooktop, the wood pellets ought to have reduced ash material and no coking.

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

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

Stockerfeed cooktops have larger flexibility to wood pellets. You must think about the home heating rate demand, automatic or hands-on slag device, flue gas warm recuperation gadget, dirt collector types and choose the most suitable wood pellets.



Actions to select ideal wood pellet fuel.

Based upon years of my experience on biomass pellet fuel production and biomass boiler advertising and marketing, I conclude the complying with steps on exactly how to select ideal wood pellet fuel.



Action 1: evaluate your wood pellet cooktops as well as boilers

Action 2: list your need on the wood pellet fuel

Step 3: study the wood pellet makes within 800 kilometres, and find out about the homes of their wood pellet fuels

Step 4: contrast the result of step2 as well as step3, and figure out the suppliers that meet your requirements

Step 5: work out the device price based on the supplied price given by the wood pellet vendors.

Pick 2 or 3 distributors and allot the purchase quantity proportionally. Remember to authorize contracts to protect an adequate supply.

Notes:


As a fully grown wood pellet consumer, you need to not just focus on the rate of pellets or the system expense of warm worth, but focus on the device price of 1-ton steam manufacturing, including the price of fuel, labor, upkeep, and also slag treatment.



Take the after-sale solution into factor to consider. Some wood pellets manufactures can supply boiler updating and also team training service.




Quality signs of wood pellet fuel

For common usages, wood pellets fuel needs to satisfy the complying with parameters. The diameter 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 web content is less than 1.5%, the sulfur as well as chlorine material should be less than 0.07%, nitrogen web content less than 0.5%, and also the heat value is higher than 16MJ/kg.



For industrial purpose, wood pellets usually have the diameter of 8-10mm and also the length of 25-35mm.



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

Density is an essential indication of wood pellet top quality. In many circumstances, the thickness of wood pellet fuel is between 1.1 as well as 1.3 t/m3. High density will enhance the expense of manufacturing. Besides, high thickness needs high compression proportion, therefore boosting the abrasion of molding dies and also reducing their working life.



As a result, we suggest to restrict the wood pellet density in between 0.8 and 1.1 t/m3. Many starters in wood pellet industry choose to make pellets with high density and high firmness. Although they looks attractive, they will minimize the manufacturing as well as increase the abrasion.
