Cremation Incinerator, 3.0M BTU/hr, 2200x1000x900mm, 2 Zones

Description

  1. Overview
    1. Incinerator type: crematorium of human bodies.
    2. Number of zones: two, primary and secondary.
    3. Primary zone: body incineration by direct fire.
    4. Secondary zone: post incineration of smokes.
    5. Operation temperatures: primary from 900° C to 950° C, secondary from 1000° C to 1100° C.
    6. Control type: both zones hi low with adjustable port solenoid valves.
    7. Number of doors: one, with automatic action by chain drive / sprocket / hydraulic cylinder.
    8. Burner type: medium speed, sealing, mixing at the nozzle, high alumina combustion block.
    9. Fuel type: LP or natural gas.
    10. Ignition system type: automatic by electric spark and supervision against flame failure by FUV.
    11. Safety train type: quick-closing, slow-opening valve with low air, gas pressure and high gas pressure limit.
    12. Feed gas pressure: 25 lb / in² (2 kg / cm²).
    13. Useful interior dimensions: length 2200 m x width 1000 mm x height 900 mm.
    14. Nominal thermal capacity: 3.0 mm BTU / hr.
  2. Thermal Insulation
    1. Floor: 4½ "thick high alumina refractory concrete, backed by 3" thick insulating concrete.
    2. Inter-zone walls and partition: 4½ "half-alumina refractory brick, 4½" insulating brick backing and 2 "insulating block.
    3. Upper walls, vault, post-incineration zone and door: 8 "thick single-module ceramic fiber and alloy metal anchors.
  3. Structural Shell
    1. Trays folded in CR cal sheet. 12 and 2 "x 3" PTR tubular profile structural reinforcements.
    2. The oven has an exterior view wall with CR cal trays. 16.
  4. Chimney
    1. Cylindrical with insulation up to a height of 3 meters with ceramic fiber and later, with a length of 3 meters without insulation.
  5. Control Panel
    1. NEMA 1, includes 1/16 DIN digital temperature controls, combustion fan starter, hydraulic unit motor starter, start / stop buttons, signal lights, fully wired and identified.
  6. Electrical Wiring
    1. THW for 600V, driven by thick wall conduit and condulets.
  7. Gas Pipe
    1. Seamless black with threaded connections for 150 lb / in².
  8. Air Piping
    1. Spiroducto and long radius connections.
  9. Refractory
    1. The load floor will be formed with 60% alumina refractory slabs and will have a 7 ° inclination towards the center of the incinerator to collect the fats and incinerate them with more efficiencies, the thickness of these slabs is 4`` / 2”. Backed with a 4̒ / 2” layer of insulating concrete for a temperature of 2000 ° F (1100 ° C). This same arrangement will also be for the smoke post-combustion chamber.
    2. The walls of the first zone will be displaced with 6 courses of 60% alumina refractory brick, it is a thickness of 4̒ / 2” backed by a 4̒ / 2” layer of 45% alumina insulating brick and finally a layer of 2” of mineral wool board.
    3. The partitioning screen of zone 1 and 2 will be made with 60% alumina refractory brick and inside this, the post-incineration smoke duct is located.
  10. Combustion Equipment
    1. For both zones, they will be fitted with sealed medium speed nozzle mixing burners with a total capacity of 1.5 mm BTU / hr.
    2. The complementary equipment is the main gas pressure regulator, shut-off and adjustment valves, manometers, combustion turbofan.
  11. Protective Equipment
    1. According to the standard, it is required and thus flame failure relays will be installed for automatic ignition and flame verification, low gas and air pressure limits, high gas pressure limit, manual reset safety valve, solenoid valves for low heat and high heat.
  12. Control Equipment
    1. The system operates in hi-low form, whose control loop consists of a solenoid valve, a type K thermocouple with a sillimanite sheath and temperature control, this is for each zone.
  13. Pipelines
    1. The combustion air pipes will be from a pipe with flanged unions, for gas it will be a black ced 40 pipe with threaded connections.
  14. Hydraulic Unit
    1. The door will be conditioned by an electric opening closing hydraulic cylinder, this will be a package type and includes a pump, tank, directional valves, relief valves, etc.
  15. Cabling
    1. It will be of the THW type for a voltage of 600 V in the caliber required by the amperage to be conducted.
    2. The electrical lines will go by conduit tube.
  16. Control Panel (Detailed)
    1. NEMA 4 type and inside the panel are installed temperature controls, combustion engine starter and hydraulic unit, start-stop button stations, signaling lights, auxiliary relays, all properly wired and identified.
    2. It will have an automatic or manual sequence PLC, panel view touch, tablet, licenses and permits, operation manual, electrical wiring diagrams for PLC inputs and outputs, PLC and HMI database, diagram designs in AutoCAD.
    3. License for a remote user, access to the wireless plant network is required to link the equipment to the local control of the oven with remote monitoring equipment.
