Waste incinerator to generate hot water

Waste incinerator to generate hot water

I. Introduction
A waste incinerator to generate hot water is a device that uses waste as an input fuel to heat water, combining modern technologies to help disinfect and treat toxic substances generated in the process of incineration. This is one of the effective solutions in waste treatment to reduce harm to the environment. Incinerators will destroy waste at high temperatures, up to over 1050°C. The heat from the hot gas from the combustion chamber will be used to heat the water in the heat exchanger system and then lead it out to serve the building’s hot water system, for household activities or other purposes. The energy provided from 5-7 tons of waste can be equivalent to the energy supplied from 1 ton of fuel oil.

II. Working process of the waste incinerator to generate hot water:
The operation of the waste incinerator to create hot water also operates on the same principle as in normal incinerators (Waste pyrolysis – Exhaust gas treatment). The difference is that, at the heat exchanger cooling the exhaust gas, the heat from the exhaust gas after the combustion chamber will be reabsorbed and reused in the cooling tower. Coldwater is led through a closed circulating steel pipe system and is in direct contact with the hot gas stream after the combustion chamber. The water will be heated to the required temperature and then used in the hot water system of the building, used for autoclaving in medical or household activities… The process of reusing heat is very efficient, it can reach 70-80% of the energy burned.

 

III. Advantages of waste incinerators to generate hot water:
Efficiently treat and utilize waste sources to become fuels for combustion
Thoroughly treat exhaust gases and toxic substances generated from waste incineration according to QCVN (Vietnamese Regulations)
Take advantage of the generated heat to serve many purposes such as heating and hot water systems; autoclave systems in the industry, medical…
