Incinerator Essay

To you, incinerators generate a lot of toxic pollutants, but if you research this topic more closely you will see that most of the toxic pollutants don’t reach the atmosphere.

Landfills are the main destination for Canadian solid waste. In 1998 nearly 21 million tones of waste was disposed of in 767 landfills, and in 45 incinerators across the country. Landfill sites generate over a quarter of the methane emissions caused by human activity in Canada, sending 1.2 million tones of this potent greenhouse gas into the atmosphere each year. Because the global warming effect of methane is 21 times greater than that of carbon dioxide, this is the equivalent of greenhouse gas emissions from more than six million cars – or 40 per cent of all the passenger vehicles in the country.

While innovative technologies have been developed to capture this gas for use as fuel in heating buildings or generating electricity, landfills are not a long term solution to waste management for future generations. Innovative programs to reduce and ultimately eliminate the need to use valuable land as garbage dumps are what is needed to ensure a continuation of the quality of life Canadians have enjoyed.

A Leader in Converting Waste into Energy St


The processed waste is loaded into the incinerator from the tipping floor by a front-end loader. Transfer rams feed the primary chamber of the incinerator and transfer the burning waste along from one stage to the next. The air quantity available for combustion is controlled so that combustion is not completed at the end of the first stage. Gases are moved to a second chamber to complete combustion and it is here that they enter the heat recovery boilers. The hot gases produced in the boilers heat water, creating steam used to run turbines and generate electricity. The incinerated waste (bottom ash) is moved into a quench tank to cool. It takes approximately five hours to burn the processed waste from the time the waste is loaded into the furnace until the ash residue is discharged from the quench tank.

Every year this mass of garbage is turned into 800,000 tones of steam which is sold to a nearby paper recycling facility to replace the use of natural gas. The revenue from the steam offsets some of the incinerator’s operating costs.

First Garbage is picked up from curbside and municipal transfer stations then hauled to the plant. The trucks are weighed on a computerized scale then dump their load into the refuse bunker which can hold up to 3,000 tones of garbage. The waste in the refuse bunker is completely contained within the plant the air that is needed for the incinerator combustion is drawn from here, so no odors can escape. Two over head cranes mix the garbage and lift it into the feed chute.

Heat and gases from the burning process is passed into a boiler room where they heat tubes of water and create steam which in turn can generate electricity and which cools the gases. In one case at the Burnaby Incinerator the steam is sold to a nearby paper mill that produces cardboard from recycled paper products.

Located in an industrial area of Burnaby, British Columbia, the Burnaby municipal solid waste incinerator is a key part of the integrated waste management system in the Greater Vancouver Regional District (GVRD). Built in 1988 the incinerator is designed to attain a minimum 85 per cent availability and a minimum plant throughput of 210,000 tones per year. The plan exceeds these expectations: availabi
