The Solid Fuel Boiler Economizer is a heat recovery equipment designed to utilize the waste heat contained in high-temperature flue gases generated in solid fuel-fired boilers. Installed in the flue gas line, it transfers a portion of the gas energy to the boiler feedwater.
The unit is designed to withstand dust and ash conditions with a durable structure and large heat transfer surface.
- Reduces fuel consumption
- Increases boiler efficiency
- Lowers operating costs
- Reduces flue gas temperature
- Minimizes environmental impact
Working Principle
Hot flue gases generated during coal combustion pass through the economizer before reaching the chimney. The gases transfer their heat to the feedwater flowing inside the tubes.
The preheated water is then sent to the boiler, improving overall efficiency and reducing fuel consumption.
Solid fuel boiler economizeris an efficient heat recovery equipment used for the recovery of waste heat contained in high temperature flue gases formed in solid fuel boilers. It is placed in the flue line and transfers some of the flue gas energy to the boiler feed water and helps the boiler system to operate with lower fuel consumption.
As a result of the combustion of coal, biomass and similar solid fuels, there is a high amount of heat energy in the flue gases. Disposal of this energy directly from the chimney increases operating costs. Solid fuel boiler economizerserves to preheat the boiler feed water by recovering this waste heat and increases the system efficiency.
Heat Recovery in Solid Fuel Boilers
Solid fuel boiler economizers are designed to withstand the ash and particle load caused by coal combustion. Thanks to its large surface area, robust pipe structure and easy-to-clean construction, it offers long-lasting use in harsh flue gas conditions.
Management Systems:
Advantages
- Reduces fuel consumption. It preheats the feed water and helps the boiler run on less fuel.
- Boiler efficiency increases: It recovers the waste heat in the flue gas to the system.
- Reduces operating costs: Thanks to fuel savings, it contributes positively to production costs.
- Reduces flue gas temperature: Reduces the amount of heat expelled from the chimney.
- Reduces environmental impact: It supports the reduction of emissions with more efficient combustion and lower fuel consumption.
Operating Principle
Hot flue gases formed as a result of combustion of coal in the boiler are passed through the economizer before going to the flue. As the gases pass through the economizer pipe surfaces, they transfer heat to the boiler feed water inside the pipes. The preheated feed water is sent to the boiler and the system works more efficiently with less fuel.
Thanks to this heat transfer, the boiler water enters the system at a higher temperature. The amount of energy required by the boiler to produce the same steam or hot water is reduced. Thus, both energy efficiency increases and the daily fuel costs of the business decrease.
Areas of Use
Solid fuel boiler economizers can be used in coal-fired steam boilers, biomass boilers, hot water boilers, hot oil boilers, and industrial boiler systems with high flue gas temperatures. Especially in continuously operating facilities, the economizer application is an important efficiency investment that saves fuel in a short time.
