Economizer It is used to increase the efficiency of the boiler as the flue gases from the boiler is made to flow through the economizer before releasing it to the atmosphere. Air preheater It is also used to increase the efficiency of the boiler by preheating the air.

Learn MoreProducts & Services. Description: The ClearFire Economizer (ECF) is ideally suited for applications utilizing the horizontal (ClearFire-H) or vertical (ClearFire-V) boiler 10-60 HP units. Gains in efficency can reach 3-5% depending on the feedwater return temperature. The Integral economizer is available for low.

Learn MoreBoiler efficiency losses arise from four major sources: 1. Heat carried away (out the stack) by the hot flue gases. This loss is usually called "dry flue gas" loss. Hotter stack tem- peratures and larger quantities of excess air increase this loss. 2. Latent heat

Learn MoreAn economizer is similar to the convection section in a direct-fired heater. Both oper-ate under the energy-saving concept of recovering some of the heat from the hot flue gases before they are lost out of the stack. The typical improvement in efficiency of a boiler

Learn MoreThere are 2 types of condensing economizers: heat exchanger and direct contact (spray). They capture much more heat and therefore can raise the overall boiler efficiency by 10% to 15%. For condensing economizers to be the most effective‚ low temperature heat sinks are required to bring the flue gas temperature well below the flue gas condensing temperature.

Learn MoreBoiler Efficiency and Combustion. A broad overview of the combustion process, including burner types and controls, and heat output and losses. This Module is intended to give a very broad overview of the combustion process, which is an essential component of overall boiler efficiency. Readers requiring a more in-depth knowledge are directed

Learn MoreBoiler System Energy Losses. The Boiler Efficiency Calculator takes into account only major energy losses‚ which typically represent 10 to 20 % of fuel input. The major energy losses associated with boilers fall into two categories: stack losses‚ and radiation and convection losses.

Learn MoreA. Economizer The exhaust gases that are leaving the Boiler contain both sensible heat and latent heat. Sensitive heat is the amount of heat needed to raise the temperature of water under constant pressure without changing the liquid state, while Latent heat is required to change Liquid state to the Vapour state at constant temperature and pressure.
