Our boiler stack economizer system will allow you to heat process water up to 140° F by utilizing the waste energy normally lost to atmosphere in your boiler stack exhaust. This system can be installed using a plate and frame heat exchanger to provide potable water. Watch our animated video to learn how Boiler Stack Economizers work.
A steam injected engine (10), including a compressor (12), a combustor (18) and a turbine (22) in series combination, with a gas flow path passing therethrough. A steam injection system is provided for adding superheated steam to the gas flow path. A water spray
Power Boiler Code, the feedpump(s) "shall be capable of supplying water to the boiler at a pressure of 3% higher than the highest setting of any safety valve on the boiler," and of quantity "to prevent damage to the boiler." Continuous Service Use centrifugal type
Lee et al 13 proposed a novel integrated boiler, and this boiler reused the exhaust gas and condensed water, so it could achieve higher efficiency and lower emission of waste heat than the previous.
Condensing Gas Boilers. Condensing gas boilers are designed to make use of the latent heat contained in their water vapor flue gas, which results in a conversion efficiency that is about 20% higher than noncondensing gas boilers. In the Netherlands, condensing gas boilers entered the market in …
Spray in Superheaters and Reheaters of High Capacity Boilers - Bright
15 tons fuel steam boiler - cfmcharitabletrust.in k-yamamoto.in. 2.5 tons capacity steam boiler coal biomass boilers. The boiler carried a heating surface of 1,233ft 2 and was pressed to 140psi except for Nos 1192-1221 with a total heating surface of 1,223ft 2 and the tender was the Johnson pattern 2,350gal type holding 4 tons of coal
9/2/2010 · Water spraying in both superheater and reheater is a very commonly adopted method. In using a spray water system, there are many points to be addressed as otherwise serious failures can result. The superheaters and reheater are sized in such a way that the full steam temperatures are achieved from 60 % boiler load.
Economizers Introduction Flue gases from large boilers are typically 450 – 650 F. Stack Economizers recover some of this heat for pre-heating water. The water is most often used for boiler make-up water or some other need that coincides with boiler operation.
Gas Boiler - an overview | ScienceDirect Topics
drying in the spray chamber. For large utility boiler applications (illus-trated here), flue gas enters the spray dry absorber at two locations: the roof gas disperser and the central gas disperser. Smaller, lower gas flow installations require only a roof gas disperser.
Warren can help cool your process hot flue gases with the technique of water spray cooling, using evaporative water spray nozzles, strategically located, either in duct or in a separate spray tower. Using micro fine mist water sprays, hydraulic or dual fluid, the very highest cooling efficiencies are accomplished and at very low cost.

Sep 08, 2010 · The spray water comes from either an intermediate stage of the boiler feedwater pump (for reheater spray) or from the pump discharge (for superheater spray). Other methods of steam temperature control include flue gas recirculation, flue gas bypass, and tilting the angle at which the burners fire into the furnace.
2. Spray type Deaerator Spray Deaerator type deaerator contains spray nozzle in feed water entry space. it's then preheated and deaerated and sent to storage section. In storage section also steam is additional to stay the water at its saturation temperature.
