Wood pellet fuels are constructed from sawdust or crop wastes. By pressing and molding, they become strong strips with the density of 0.8-1.4 t/m3. Wood pellets fuel has the exact same power density as tool coals. The burning impact has improved a great deal compared to large products. Besides, wood pellet fuels are convenient to store and transport.
Which has higher cost performance?
The quality of biomass pellet fuel differs with the raw products it is made. Typically, there are high quality sawdust pellets, usual wood pellets, bamboo pellets, peanut shell pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medicine deposit pellets, organic sludge pellets, and so on. They have various prices, homes and application locations and target at details customers.
For venture as well as individual individuals, it is not a good idea to pick top notch sawdust pellets or low-price rice husk pellets all the time.richi pellet machine
need to select the wood pellets with high cost performance as well as matches your biomass boiler.
Rice husk pellets vs sawdust pellets
Rice husk pellets is a common biomass pellet fuel It has reduced rate as well as inferior quality than sawdust pellets. Besides, it has narrower application locations than sawdust pellets.
Excellent quality sawdust pellets can be used in large stokerfeed boiler, fixed grate boiler, heater, hot-blast range, smelting heating system, etc. Although the cost is higher than rice husk pellets, sawdust pellets is in excellent need. In high seasons, the high quality wood pellet supply is in lack.
Which wood pellet boiler do you utilize?
For taken care of grate boiler or little pellet burner, you should choose those without coking.
For hot-blast range, the wood pellets should have low ash content as well as no coking.
For smelting heating system, the wood pellets should have high warmth worth and the unstable separating rate is high.
For thermal oil boiler, the wood pellets must have low ash web content without coking, and also the heat worth and the volatile separating price is high.
Stockerfeed ovens have larger versatility to wood pellets.richi pellet mill
ought to take into consideration the home heating rate demand, automatic or hands-on slag device, flue gas warm recuperation device, dirt collection agency kinds and also choose one of the most ideal wood pellets.
Actions to pick ideal wood pellet fuel.
Based upon years of my experience on biomass pellet fuel production as well as biomass boiler advertising and marketing, I end the adhering to steps on how to choose suitable wood pellet fuel.
Action 1: examine your wood pellet stoves and boilers
Step 2: listing your requirement on the wood pellet fuel
Step 3: study the wood pellet produces within 800 km, and find out about the buildings of their wood pellet fuels
Tip 4: compare the result of step2 as well as step3, as well as discover the vendors that meet your demands
Tip 5: exercise the system expense based on the delivered rate provided by the wood pellet vendors.
Select 2 or 3 distributors as well as designate the acquisition amount proportionally. Keep in mind to authorize agreements to safeguard a sufficient supply.
As a fully grown wood pellet consumer, you should not just focus on the cost of pellets or the unit expense of warmth value, however pay attention to the system expense of 1-ton vapor manufacturing, consisting of the expense of fuel, labor, maintenance, as well as slag treatment.
Take the after-sale solution into consideration. Some wood pellets manufactures can provide boiler updating and also team training service.
Quality indications of wood pellet fuel
For typical uses, wood pellets fuel needs to meet the following criteria. The diameter is 6-12mm, the size is 2-4 times that of size, and the bulk 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 as well as chlorine web content should be less than 0.07%, nitrogen material less than 0.5%, and the warm value is higher than 16MJ/kg.
For industrial purpose, wood pellets normally have the size of 8-10mm and the size of 25-35mm.
What's the most effective thickness for making wood pellets?
Density is a vital sign of wood pellet top quality. In the majority of scenarios, the density of wood pellet fuel is between 1.1 as well as 1.3 t/m3. High density will certainly raise the price of manufacturing. Besides, high thickness calls for high compression proportion, thus raising the abrasion of molding dies as well as reducing their working life.
Therefore, we advise to constrain the wood pellet density between 0.8 and also 1.1 t/m3. Lots of beginners in wood pellet market favor to make pellets with high density and also high solidity. Althoughsmall electric fish feed extruder machine price
