Despite the seeming impossibility of automated solid-fuel heating system, this option has long existed and is offered on the market. Get more background information with materials from James. This so-called pellet boiler, the boiler is operating a pellet. Pellets – a granulated wood sawdust and shavings, which are compressed using special equipment. The absence of any additives for bonding chips ensures ecological safety of this type of fuel, and granulation allows you to burn pellets with virtually no residue, which indicates a very high level of efficiency of such equipment. With an adequate supply of pellets, a boiler can work for several months without any human intervention. The presence of a variety of sensors and actuators, as well as the obligatory fire isolation, makes this system fireproof and easy to manage and operate. But as always, a complex system is expensive, and setting and installation of such systems is carried out by a qualified technician. In addition, for the storage of pellets requires a dry room of impressive dimensions.
So, what do we have? Sophisticated automated heating system solid fuel, which works on the principle of automatic feeding the required amount of fuel and air with feedback from various sensors and sophisticated microprocessor-controlled filling. Now let try to speculate on the theme of simplification of the system and try to find inexpensive options for automation of solid fuel combustion. From complex to simple. The biggest problem Automation of solid fuel lies in the fact that this fuel has a fairly large size of individual particles. To become clear, such an example: it is no wonder pellets to automate the burning process, because they are small in size, it is convenient to push through, fill out the required volume. Theoretically this is possible with a very small fraction of coal and sawdust.
But sawdust, fine coal and wood pellets are a result of preliminary processing of solid fuels is a faction with which we encounter in everyday life. From this we can conclude the following. To automate the operation of the boiler on the basis of pellet, requires pre-processed and prepared fuel. Options for implementation of this approach: – to buy ready-made pellets, or make them yourself. It is sometimes rational, when there is a free raw materials for manufacturing: dumps opila sawmills, or own woodworking business. – Split into the desired fraction of coal. Very messy and noisy process. – Chop wood chips in the common tree. This can be wood, stumps, branches, etc. It turns out that for the mechanical automation combustion of solid fuel is required prior preparation of fuel, which requires time, effort and energy. Is not there another way? There. This method is not based on mechanical automation, and the accumulation of heat in a short period of time and efficiency of stored heat long term. This method involves the application of heat storage.
