Which has greater price performance?
The quality of biomass pellet fuel varies with the raw products it is made. Usually, there are top quality sawdust pellets, common wood pellets, bamboo pellets, peanut covering pellets, rice husk pellets, maize stalk pellets, animal dung pellets, sugar or medicine residue pellets, natural sludge pellets, and so on. They have various rates, buildings as well as application areas and also target at certain customers.
For venture and also individual users, it is not a good idea to choose high-quality sawdust pellets or low-price rice husk pellets constantly. You ought to choose the wood pellets with high price efficiency and also suits your biomass boiler.
Rice husk pellets vs sawdust pellets
Rice husk pellets is a common biomass pellet fuel It has reduced rate and substandard top quality than sawdust pellets. Besides,animal feed pellet machinehas narrower application locations than sawdust pellets.
Premium quality sawdust pellets can be applied in large stokerfeed boiler, fixed grate boiler, burner, hot-blast oven, smelting heater, etc. Although the price is more than rice husk pellets, sawdust pellets remains in excellent need. In high seasons, the high quality wood pellet supply is in shortage.
Which wood pellet boiler do you make use of?
For taken care of grate boiler or small pellet heater, you need to select those without coking.
For hot-blast oven, the wood pellets ought to have low ash web content and also no coking.
For heating system, the wood pellets ought to have high warmth worth and the unstable separating rate is high.
For thermal oil boiler, the wood pellets need to have low ash material without coking, and the warmth value and the volatile separating price is high.
Stockerfeed stoves have larger adaptability to wood pellets. You need to take into account the heating price need, automatic or hand-operated slag tool, flue gas warm healing tool, dirt collector kinds and select the most suitable wood pellets.
Actions to choose ideal wood pellet fuel.
Based upon years of my experience on biomass pellet fuel manufacturing and biomass boiler advertising and marketing, I wrap up the adhering to steps on how to select suitable wood pellet fuel.
Step 1: analyze your wood pellet ranges and boilers
Action 2: listing your requirement on the wood pellet fuel
Step 3: study the wood pellet produces within 800 km, and learn about the homes of their wood pellet fuels
Step 4: contrast the outcome of step2 as well as step3, and also find out the suppliers that satisfy your requirements
Step 5: exercise the system expense based on the delivered cost supplied by the wood pellet distributors.
Choose 2 or 3 vendors and allot the acquisition quantity proportionally. Remember to authorize contracts to secure an adequate supply.
Notes:
As a mature wood pellet consumer, you should not only focus on the price of pellets or the system price of heat worth, however pay attention to the unit price of 1-ton steam production, consisting of the cost of fuel, labor, upkeep, and also slag therapy.
Take the after-sale solution into consideration. Some wood pellets manufactures can provide boiler updating and also personnel training solution.
Quality signs of wood pellet fuel
For usual uses, wood pellets fuel needs to fulfill the adhering to criteria. The size is 6-12mm, the size is 2-4 times that of size, and the bulk thickness 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 content should be less than 0.07%, nitrogen web content less than 0.5%, as well as the heat value is more than 16MJ/kg.
For industrial purpose, wood pellets typically have the size of 8-10mm as well as the size of 25-35mm.
What's the very best thickness for making wood pellets?
Thickness is a vital indication of wood pellet high quality. In many situations, the thickness of wood pellet fuel is in between 1.1 and 1.3 t/m3. High thickness will certainly raise the cost of manufacturing. Besides, high density calls for high compression ratio, therefore raising the abrasion of molding dies and also shortening their working life.
Therefore, we recommend to constrain the wood pellet thickness in between 0.8 as well as 1.1 t/m3. Numerous starters in wood pellet market choose to make pellets with high density and high solidity. Although they looks attractive, they will certainly reduce the production and also enhance the abrasion.
