Pellet Stove Problems Due To Fuel Ash Changes and Clinker Formation

It's a sad fact, in the new and emerging pellet fuel and pellet burner industry, but there is some poor quality pellet stoves and boilers out there on the market, which are simply not capable of dealing with 'real world' pellet fuels. What is meant by this comment is, many of these poor quality pellet stoves and boilers are built to handle the perfect fuel, and only the perfect fuel. This means a pellet of perfect length, density, ash content and moisture. Even the highest quality premium wood pellets on occasion will produce some pellets which aren't perfect. This should obviously be expected as pellets are a by-product of natural resources and also that you cannot presume that the consumer has purchase prefect fuel. The manufactures of these low quality pellet burners use the excuse of the poor performance that its due to the consumer purchasing poor quality pellets. However other quality pellet burners would not even skip a beat.

What Is It That Makes These Stoves And Boilers Such Poor Quality?

Well, it all comes down to cost, and trying to produce a product with the bare minimum of capabilities to pass the initial test and scrape through a years worth of burning to get through the warranty. What makes them so poor is a combination of poor quality materials, poor design and poor construction. Take as an example the grade and thickness of steel used to produce the fire box. All pellets and particularly other biomass pellets which will be much more common in the future are quite corrosive. To withstand this corrosion, it basically comes down to the thicker the better, just a like a coal boiler which last 40 years, and no fuel pellet is as corrosive as coal. However, thicker steel costs, so some manufactures use thin grade steel, which makes purchasing these cheaper stoves a false economy, as the stove will not last half as long as better more expensive units. However these better quality units are not that much more, but the benefits easily justify the increased cost. You have to remember when buying a pellet stove or boiler that it is a long term purchase so it must last.
