PRODUCT DESCRIPTION
The feeder elbow is one of the elements of the boiler fuel feeding system. It connects the fuel tank with the burner. Thanks to the screw conveyor placed inside the elbow, the fuel is fed into the combustion chamber. The elbow has a characteristic design and is part of a set patented by the company Pancerpol. This elbow is used in 15kW feeders. It is made of cast iron. It is mounted to the feeder body - the air chamber - using 4 screws. This is an original product with which Pancerpol equips its fuel feeding systems. Thanks to the use of the highest quality components, the elbow is very durable, aesthetically made, and guarantees long-lasting and trouble-free operation.

WHAT ARE FEEDER ELBOWS MADE OF?
Cast iron – a casting 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 mold filling, 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 OPERATION PRINCIPLE
The Automatic Fuel Feeding Unit, which includes the fuel tank, fan, and microprocessor controller, creates a system for storing and automatically feeding fuel to the burner and leads to the most economical combustion process in a continuous system. The transport of fuel from the tank to the retort burner is carried out by a screw feeder. The fuel is pushed onto the grate of the firebox 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 afterburning grate, forming a fuel heap 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 amount of air needed corresponds to the screw rotation speed. The fuel, which slowly moves out of the crucible, goes 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.
