Hot Stack
Boiler Stack Heat Recovery and Direct Contact Hot Water Heaters
Boiler stack heat recovery
is an energy efficiency strategy that involves the preheating of water via the maximization of heat generated by boiler flue gases. It is employed with the help of a stack economizer. By utilizing recovered stack heat, economizers can preheat feedwater in utility steam boilers. Economizers generally come in either single or dual stage designs, and they are often paired with direct contact hot water heaters to boost energy recovery.
Direct contact water heating systems are widely used in industrial operations. Industries needing constant supply of hot water such as food processing, cleaning and aqua farming employ such systems. Pharmaceutical, laundry, and hotel companies also rely on direct contact water heating.
The recovery resulting from the synergy of economizers and direct contact hot water heaters is very notable. It involves the increase of stack gas density which permits smaller stack diameter, enhancement of combustion efficiency which reduces the amount of excess air needed by the burner and the amount of stack gas and pollutant emissions, increase of pollutant concentration which makes the removal of such detriments more manageable, and reduction of sulfur dioxide emission into the atmosphere. It also eliminates the need for constant heating and reheating to produce the required supply of hot water. Additionally, it enables the generation of process water that can be used as a medium for reaction, crystallization, or fermentation.
Businesses that utilize
direct contact hot water heaters
can recover as much as 50% of the heat generated by boiler flue gases and waste water streams. If their heaters generate hot water at 95% to 100% efficiency, they can expect more significant reduction in energy costs. Lowered costs in utility consumption and processes can directly signify the reduction. More importantly, businesses relying on the said equipment can extend the life of their heating system, reduce the system’s size, and use extra energy to cover and minimize auxiliary energy needs.
Fueling direct contact hot water heaters is also manageable since there are various options. Such options include electricity, fuel oil and gas and even solar energy. To choose the best primary fuel for their heaters, companies need to carefully evaluate the availability of the equipment that use their preferred fuel, business demands, equipment cost, fuel availability, fuel space and storage requirements, and regulatory specifications.
Every
direct contact hot water heater
is designed for a particular condition or nature of work, so it is beneficial for businesspeople to contact trusted specialists in choosing the equipment they need. Recovery schemes and designs for making heating systems more eco-friendly can be consulted with such experts. When properly chosen, heaters can facilitate optimal boiler stack heat recovery to improve energy efficiency.
