3, furnace main body material
A. Main combustion chamber: high aluminum phosphate is used in cremator.
B. Secondary combustion chamber: special refractory high-alumina bricks are used.
C. oven door: the outer oven door is decorated with 304 stainless steel and lined with heat-resistant insulation fiber.
D. Burner: igniter is adopted, and the combustion angle can be adjusted; Automatic ignition, automatic oil supply, automatic air supply and automatic monitoring should be provided with safety protection devices.
4. Fuel used: 0-10# light diesel oil (fuel oil or city gas, natural gas and liquefied gas as required by users).
5. Fuel consumption: continuous cremation fuel consumption (three sets): about 8-12 liters/set.
6. Average cremation time: ≤45 minutes/set.
7. Furnace working temperature: 400℃ ~ 900℃;
8. The working temperature of the secondary furnace: 850℃ ~ 1050℃, and the fire resistance temperature of the brick structure in contact with the flame surface of the main combustion chamber and reburning chamber is above 1200℃;
9. Smoke emission: It conforms to the national standard of Emission Standard for Air Pollutants in Crematorium (GB13801-2015), and the smoke blackness value is not greater than Grade I in Lingemann.
10. Smoke exhaust mode: adopt jet chimney structure to discharge.
11. Working pressure of main furnace chamber:-3 ~ -3～-35Pa.
12. Power consumption: blower: air volume: ≥ 2,700 nm3/h, wind pressure: ≥ 10,700 Pa; Motor power: ≥7.5Kw; Induced draft fan: air volume ≥ 8,881 nm3/h, air pressure ≥ 2,087 Pa; Power: ≥7.5 kw
13. Total power: no more than 25kW/set.
14. Control system: The operating system of all programs of the equipment adopts LCD screen as the operating interface, PLC programmable system and computer automatic control. It must also have automatic, semi-automatic and manual functions (which can switch functions) and can switch functions according to needs;
15. The ashes cooling system adopts a translation lifting transposition mechanism. When the hot kang surface is discharged from the furnace, it is cooled and lifted by a translation car, so that it can leave the remains transport car and translate the hot pit surface under the ashes cooling cover for ashes cooling. Then, the cold kang surface is put on the body conveyor by transmission, and the body conveyor sends the body into the cremation furnace for cremation.
16. Underground flue: the underground flue is reasonable, the inner diameter of the flue is above 700*700 mm, the refractory material is made as required to ensure the smoke to pass through, the waterproof layer has good waterproof performance, the stainless steel U-shaped groove is installed, and the flue is equipped with a filter system. The chimney adopts 4MM thick stainless steel plate, and the chimney ejector adopts 4MM thick stainless steel. Designed service life ≥30 years.
17. Monitoring system: industrial-grade LCD color monitors of 15 inches and above are used to monitor the products with 1/3 "resolution of the camera ≥1280×1201, and monitor the smoke emission.
18. Surface temperature of cremation furnace: the temperature rise of the furnace surface is ≤45℃, and the temperature rise of the observation hole handle is ≤55℃;
19. In the electrical control system, the low-voltage appliances are used according to or equivalent to the brand "Schneider", the touch screen and programmable controller are used, and the rest must be made of high-quality materials. Control lines and cables should be protected by asbestos sleeves to prevent line failure or leakage caused by high temperature aging.
20, cremation machine power supply system and the main circuit should have automatic load protection switch, motor and other loads should have overload protection.
21. A tool rack is installed beside each furnace, and two flue manholes are installed on both lateral sides of the furnace body.
22, each furnace oil gun base and the furnace body should be more than 25 cm apart, and the power cord of the oil gun base should be insulated and fireproof.
23, cremator fan air inlet should be equipped with protective net.
24. When the cremator is running, the main combustion chamber and reburning chamber of the cremator shall be kept under negative pressure to prevent the smoke from overflowing.
25, cremator burner should be equipped with safety protection device, ignition, safety ignition time is 5-7s, such as ignition failure, safety protection device can automatically cut off the fuel supply.
26. The cremation machine should be separated from the furnace body by switches, circuits and electrical appliances. The manual operation panel of each furnace should be installed at the edge of the furnace body, the computer display screen should be installed at the upper right of the furnace body, and the low-voltage circuit control box should be externally arranged to avoid the high-temperature position of the furnace body, so as to prolong the service life.
27. Honeycomb flue gas filtering device for cremator flue gas return: The circumferential inner wall of the flue gas main pipe of the honeycomb flue gas filtering device for cremator flue gas return is provided with a threaded groove near the top end, and a bearing holder is screwed in the threaded groove, and a sliding bearing is embedded in the middle of the bearing holder. When in use, when the flue gas is ejected from bottom to top, the rubber ball will be propped up upwards and the air holes will be opened, so that airflow can pass through and the cleaned dust can be prevented from falling below the flue gas main pipe.
