The Incinerator Plant is output wastes incineration from Different petrochemical units. In this project we want to incinerate all output wastes from petrochemical units and also produced high pressure steam from incinerator plant heat generated. At first output waste from petrochemical collects and transfers to transit and sorting center in various forms. Input feeds of incinerator plant are shown in below table:
Waste streams of petrochemical unit collect and store in Transit and Sorting Center. In Transit and Sorting Center one laboratory must be considered. In this center, waste will be classified in two groups: –Unsuitable for burning –Suitable for burning Unsuitable waste for burning can be divided into the 4 categories: –Buried materials –Materials (wastes) that need to be stabilized before buried –Materials (wastes) that can be sold. –Wastes that can be returned to petrochemical. Suitable wastes are classified into the two categories: –Input wastes to rotary kiln, consist of solids and waste fluids. –Input wastes to static kiln, consist of clean fluids and gasses. All solid wastes must be transferred to storage pit from Transit and Sorting Center. Solid wastes storage pit is input of rotary kiln. All fluid wastes must be stored and stabilized in Transit and Sorting Center. All storage and stabilization devices or facility must be considered. Storage and stabilization devices (facility) consist of: Tanks, Pumps (Transfer, Loading & Unloading), Agitator (Mixer), Blanketing System, Flare system, Instrumentation and Control Systems, etc Storage and stabilization capacity must be considered based on worst case (shut down). Generally incinerator plant consists of two similar trains (capacity of each train is 100%). Each train consists of a rotary kiln and a static kiln. Based on client request, efficiency of incinerator plant is 99.8% for all components and for aromatic must be higher than that amount. Please be attention, produce high pressure steam from output heat of incinerator plant is in this scope of work.

We are looking for small incinerators with filter (with least minimum pollution) for burning/combusting 5kg/hr, 10kg/hr, 15 kg/hr, 20kg/hr, 25kg/hr to 50kg/hr and 300kg/hr of SOLID ORGANIC DRY AND WET NON-HAZARDUOUS of any kind (including hospital wastes) per day or per hour. Should it be with no smoke, no fumes, no odour (smell), no dust, no emission of solid particles and with least minimum pollution (within national and international standards). Must be environmentally healthy and acceptable with international standards. Should not be with water scrubbers. Ash contents after burning should be 3-4%.
During the manufacturing and after packing, we generates some waste like, chicken bones, some fried products, vegetable waste, biscuits, chocolates (Paste), Plastics, foils, packaging materials, etc. We normally separate the organic waste to make compost. The restout need disposal. At present, we send it to landfill site. But We want to install an incinerator for such waste. The approx quantity is about 4 ton per day.
– medical waste incinerator solutions and prices for 100 bed / 500 bed / 1000 bed / 3000 bed hospitals.
– Assumption: general hospital beds 50%, operation beds 50% for the 100 bed hospital case, while this ratio is 30-70% for the other cases
– international standards and waste creations assumptions should apply
It will always be our preference that the client pre-incinerates / use of pyrolysis (conditions) the raw e-Waste (printed circuit boards, computer memory etc.) which will allow our plasma smelting furnace to treat a concentrated waste, but increasingly, we are being asked to provide a complete turnkey plant including pre-incineration / pyrolysis of the e-waste.
We require indicative information and a budgetary cost please for an incineration / pyrolysis plant that will handle about 3000 tonnes per year of raw E-waste producing about 2000 tonnes per year of Integrated Circuit (IC) Sweeps. Here we assume about a 30 – 35% weight loss due to the removal of volatiles.
Close the door.
Obtaining the combustion cycle during which no monitoring service ( duration 2 hours ) is required.
The combustion cycle automatically ensures :
Starting the secondary air fan.
After 10 minutes, the afterburner is temperature:
?Turning on the automatic burner combustion chamber , which guarantees the output of the gasification of waste. The operating time of the burner is programmable according to the type of waste, using an adjustable mechanical timer from 1-60 minutes.
Automatic start of combustion air fan.
After 2 hours , the end of ” combustion cycle ” automatically guarantee :
The closure of primary air servomotor .
The post-combustion burner off.
During charging , opening the door automatically ensures immediate shutdown fan primary and secondary air . At the end of the combustion cycle the fan primary / secondary air and burner continues to run for 2 hours to protect the burners and to cool the oven . After this time the program automatically turns off the installation completely .
Ideally, we would like the supplied information to cover material loading/unloading, the incineration / pyrolysis process and the off-gas system (scrubbers etc.). Our understanding is that pre-incineration is conducted to homogenise the waste and to minimise the subsequent losses of species at the smelting stage through the formation of chloride/bromide salts and through oxidation losses, i.e. the halogens being driven off at a lower temperature to that at which the salts/oxides could boil in the smelting stage.
