Incinerator

Understanding Incineration

The incineration process can be understood through a triangular puzzle. This triangle is an isosceles triangle with two equal and one unequal side. The three sides represent the 3Ts of incineration i.e. Time, Temperature and Turbulence. If one side is decreased then there has to be compensatory increase in the other two. A perfect balance between all three has to be maintained for successful incineration. And BLACKHOLE incinerators have achieved this perfect balance -
1100°C (Tp) + 2Sec (Tr) + Tb = BLACKHOLE

The procedure of incineration involves feeding the waste through the Charging Door in the Primary Combustion Chamber (PCC) where the Primary Burner heats it and completely degasifies it under sub-stoichiometric conditions. The gases and volatiles that are formed then proceed to the Secondary Combustion Chamber (SCC) where these are completely incinerated by the Secondary Burner at very high temperature with excess combustion air. A key role is played by Ejector and Combustion Air Fans. The former cools down the flue gases that emanate from the SCC before they are released into the environment. This rapid cooling prevents the formation of dioxins and furans. The fan is also connected to a Venturi Ejector which maintains negative draft in the incinerator thus allowing the incinerator to be loaded while in operation. The Combustion Air Fan provides the combustion air in the incinerator.

The ash leftover in the PCC is sterile and can be removed through the Ash Removal Door. A separate Ash Chamber is provided in the PCC for wastes which have high ash content.

BLACKHOLE Incinerators

BLACKHOLE incinerators are twin chamber, fixed hearth, pyrolytic and controlled air incinerators available up to a capacity of 500 kgs/hr for solid and 1000 kgs/hr liquid wastes. For lesser amount of waste we also supply packaged incinerators with the capacity of up to 50 kgs/hr. Incinerators with capacity of more than 50kgs/hr are supplied in SKD conditions and are later assembled on site.

Burners

Our incinerators have CE certified high efficiency burners that are sourced from Europe. They are fully automatic and well equipped with various safety devices like Flame Failure Protection Device etc.

Controlling Systems & Automation

The entire process is operated and controlled by a tamper proof PLC based fully automatic control panel. The sensors, safety interlocks and audio visual alarms installed in the system ensure a safe and trouble free operation. The motors are operated by Variable Frequency Drives (VFD) installed in the control panel.

Why Incinerators?

Industries and municipal authorities have always struggled with the mechanisms of waste reduction and the methods previously used for waste disposal are getting limited. Due to the rapid urbanization and industrialization, waste management concerns are becoming critical. Landfill sites are shrinking and hazardous wastes cannot be dumped in landfills without treating them. Therefore incineration is the most attractive option as compared to other disposal methods. Here is why:

•	Volume of the waste incinerated is reduced by 90-95% and therefore the life of landfills increases.
•	Waste reduction is immediate.
•	Ash is sterile and can be safely disposed off in a normal landfill. This eliminates the need of having any special kind of landfill. In some cases, ash can even be recycled as construction aggregate.
•	Hazardous component of the waste is destroyed.
•	Waste can be incinerated on site without having the need of transporting it to some other place.
•	Emissions after combustion can be effectively controlled by installing air pollution control devices such as gas scrubbers etc.
•	Incinerators require relatively small area for installation unlike land disposal methods which require huge area.
•	The running cost can be reduced by recovering the heat in the form of generating electricity, hot water, steam etc.

Busting the myths The use of incineration system is surrounded by some myths. Here we bust them:

•	Incinerators emit harmful dioxins and furans.
	Truth: The design and technology of incinerators and air pollution control devices has advanced by leaps and bounds over the past few years and this has resulted in drastic reduction of dioxins and furans.
•	Incinerators leave behind toxic residue.
	Truth: The ash that is left behind is sterile and can be disposed of safely in a normal landfill.
