WHAT IS THE FIREPLACE MADE OF?

Cast iron – a foundry alloy of iron with carbon, silicon, manganese, phosphorus, sulfur, and other components, containing from 2.11 to 4.3% carbon in the form of cementite or graphite. The occurrence of a specific carbon phase depends on the cooling rate and the chemical composition of the alloy. Slow cooling favors the precipitation of graphite. Alloying additives also play a certain role here. According to the applicable standard, cast iron is defined as a material whose main component is iron and in which the carbon content exceeds 2% (the presence of large amounts of carbide-forming elements may change the stated carbon content).

Cast iron is characterized by low casting shrinkage, ease of filling molds, low melting temperature, and low production cost, and after solidification, it features high machinability, which makes cast iron one of the most commonly used casting materials in machine construction.

FEEDER OPERATING PRINCIPLE

The Automatic Fuel Feeding Unit, which includes a fuel tank, a fan, and a microprocessor controller, creates a system for storing, automatically feeding fuel to the burner, and leads to the most economical combustion process in a continuous system. Fuel transport from the tank to the retort burner is carried out by a screw feeder. The fuel is pushed onto the grate of the fireplace through a crucible placed in the center of the grate. The fuel moved by the screw located in the feeder tube is evenly spread in the crucible, then on the afterburner grate, forming a fuel pile divided into combustion zones. The air needed for the combustion process is supplied by a forced draft fan. The screw rotation speed can be changed by the microprocessor controller depending on changes in the boiler's heat output. The screw speed requires an appropriate amount of air. The fuel, which slowly exits the crucible, passes through all combustion phases, i.e., drying and heating of the fuel, release of volatile parts, coke burning, oxygen reduction, and coal burnout from the slag.
