The owner of the greenhouse shows the furnace which they previously used to burn coal to warmth their greenhouse, is now combustion grass pellets. The greenhouse owner explains how the furnace running on grass pellets could easily warmth any farm dwelling within the county. He then proceeds to open the bag of straw pellet energy plus load it into the hopper on the furnace. He then proceeds to remove in addition to empty the large ash draw, which fits within the furnace direct beneath the burn grate. The hopper has a horizontal auger in the base which will feed pellets up into the burn pot. The owner explains one of the reasons he likes this design of pellet furnace is because of the design of the grate. He explain as ash is formed the new feed of pellets pushes the ash over the grate, in addition to into the large ash pan below. To ignite the grass pellet furnace either fire starter gel, or in the video a flame torch is used to ignite the fire. A fan then feeds the fire with air to achieve an proficient burning.

A few minutes after starting the fire, the incineration zone of the grass pellets is around 600 degrees. Using an infrared heat sensor, the owner of the greenhouse shows how efficient the pellet stove furnace is at capturing warmth, by means of the chimney gases leaving the smokestack at only around 70 degrees. The flue gases still need to be hot ample, so creosote does not form around within the pipe, as eventually this would choke the furnace. Within a few more minutes the heat of the burning zone has reached 1000 degrees. At these tempters highly efficient incineration is taken place, volatile gases are being burnt off as well as no visible smoke. At these temperatures the flame appears blue, similar to a gas flame. As stated within the video, compared to coal, grass pellets are not only a much greener choice, there are also a renewable resource. The straw pellets burn cleanly, generate no odour during combustion. The owner describes the process of using straw pellets as a win, win scenario for the consumer and manufacturer of the pellets.

Combustion grass pellet fuel is not as straightforward as burning wood pellets for case. Yet, despite the issues, burning grass pellets is definitely worth as the resources are far more abundant than wood and straw pellets can be a much cheaper along with more available fuel source. The three main issues involved in incineration grass pellets are increased ash content, potential clinker formations along with increased corrosion risks. Grass pellets produce chloride which is a high temperature corrosive, to withstand the increased corrosion risk, the furnace must be either built from stainless steel or heavy grade steel. To deal by the increased ash content and clinker formations, only certain burn pot designs can remove enough ash as well as also possible clinker formations. The issue is most pellet stoves as well as pellet boilers are designed by a very basic drop down burn pot. Clinker formations are were the ash reaches a high enough heat to fuse together plus form a solid glass like mass. The PelHeat pellet stove along with boiler guide shows which design of burn pot in addition to additional issues to avoid.
