Flat-Bed Cremator

top

The special construction of the H · R · Heinicke - the flat-bed cremator - consists of a furnace slide door, a cremation chamber (primary combustion chamber), an afterburning chamber (secondary combustion chamber), a cease-burning chamber and as well an ash cooling zone. The mentioned areas of the oven are completely produced by using materials of high quality, mass-produced fire-bricks and insulating materials including the necessary specially shaped bricks. The material qualities are selected according to the different thermal, chemical as well as mechanical requirements.

The material selection is based upon the H · R · Heinicke know-how resulting from more than one hundred designed and implemented facilities which are operating successfully.

The main burning chamber and the afterburning chamber located upon each other represent a compact construction with an optimum heat exchange between the combustion chambers. The result is a very short preheating time and extremely low primary energy consumption with the advantage that no preheating of the combustion air is necessary. The supply of the combustion air is effected by means of a combustion air blower with the result of lower investments and saving of maintenance costs as well as electrical energy consumption above all.

Alternately three burners operating with oil or gas ensure the supply of additional energy in the main burning chamber, afterburning chamber and cease-burning chamber if necessary.

According to our experiences the operation of the burner will be only necessary in the beginning of the cremation for preheating the whole furnace system. During the cremation the temperature is normally released by the combustion of the coffin and the body which are sufficient for an independent combustion. Only in the end of the cremation process it may be necessary that especially the afterburner readjusts the temperature to a value of 850 °C in the afterburning zone. This value is required by the authorities.

The cremation process will be controlled by Direct Digital Control (DDC) to guarantee secure operations. Measurements of temperature and oxygen in co-operation with the combustion air and the burning system ensures that optimum combustion conditions will be achieved at any time.

In a flat bed furnace the body remains on the floor of the primary combustion chamber during the whole cremation process. Thus the carrying of ash particles within the flue gas will be minimized compared to the free-falling type furnace.

After the combustion is nearly completed only the residues of the incineration will be fed into the cease-burning chamber and thereafter into the cooling zone.

H · R · Heinicke´s latest development, the coffin insertion and ashes-removal system ensures

the movement of coffins adapted to all usual shapes of coffins and their prompt insertion into the primary combustion chamber.
the complete sweeping of ashes into the cease-burning chamber in view of careful treatment of the combustion chamber floor and comfortable handling.
fast operation to minimize the cooling of the furnace to avoid the inlet of cold air.

The design of the machine corresponds to the expected mechanical and thermal charges (coffin weights up to 300 kg). Safety directed control of the machine is achieved by directed link with the furnace. The machine consists of a robust steel construction which is located in starting position in a pit in front of the flat-bed cremator in the coffin insertion zone. The supporting beams of the coffin insertion machine are in flush with the floor.

The insertion machine developed by H · R · Heinicke complies with the intended targets in every respect.

	Flue Gas Cleaning
	top Flue gases caused by the cremation are chilled by flowing through the flue gas heat exchanger. There is one chiller for each cremation line. Via the subsequent cyclone filter which works by using the force of gravity larger dust particles and sparks within the flue gases are carried out. The flue gas itself leaves the cyclone and is led to the filter (e.g. flat bag filter) . The flue gases are cleaned there by using additives which are available in the reactor of the filter plant and the subordinate filter elements. The quality of the cleaned flue gas (cleaned gas) is measured by the ejection instrumentation (CO, O2 and dust) realized in the filter plant and flue gas fan and recorded by the ejection evaluating arithmetician device. Coming from the induced draught fan the cleaned gases are discharged to atmosphere through the chimney installation. The flue gas heat exchanger is cleaned automatically by using a soot-blower. The filter bags of the filter plant are cleaned automatically depending on differential pressure. The cleaning works by using compressed air - dry and oil-free. View to the filter plant
