Caravan Modular Boiler Gas Steam Application Guide

VENTING A GAS-FIRED SYSTEM A boiler venting system provides an escape path for the products of combustion. There are three major components for venting a gas-fired Caravan: a draft hood for each module, a breeching manifold and a chimney. Draft Hood The draft hood is part of each boiler module, although shipped in a separate carton.

Application Note: Flue Gas Analysis as a Boiler Diagnostic

Flue Gas Analysis as a Boiler Diagnostic Tool Overview, and Traditional Application Combustion flue gas analysis has been used by Power Plant Operators for decades as a method of optimizing fuel/air ratio. By measuring the amount of excess oxygen and/or CO in the flue gases resulting from combustion, plant operators can operate at the best

Boiler (power generation) - Wikipedia

The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300–1,600 °C (2,372–2,912 °F). Some superheaters are radiant type (absorb heat by thermal radiation), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the

Modeling of a steam boiler operation using the boiler

May 15, 2019 · Considering that the values of the air and flue gas temperatures are low, an exact history of the tube wall temperature along the air flow path is not necessary. Fig. 7 presents the location of the air heater individual stages in the boiler second duct. Fig. 8 presents changes in the flue gas and air temperatures in the air heater individual

Jan 24, 2016 · After these consecutive heat transfer zones the temperature of the flue gas goes down. After passing through APH flue gases pass through ESP (Electro Static Precipitator). ESP is nothing but dust /fly ash removal system. After passing through ESP flue gas goes to ID (Induced Draft) fan. ID (Induced Draft) fan suck that flue gas and throw it to the Chimney. In flue gas the amount of oxygen is …

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived

Flue gas dampers | Jeremias UK - chimney systems

Flue gas dampers. Flue gas dampers are installed in the connection pipe between a boiler and the chimney and close the flue gas path, if the chimney is no longer in use. The flow safeguard prevents the cooling down of the heat generator and the plant room, which helps to save energy. In addition they prevent a possible influx of exhaust gases

Flue gas condensation systems are designed in two ways: as a single-stage recuperative shell and tube heat exchanger and two-stage systems with the first stage of the cooling recuperator (dry economizer, DE) and the second stage in the form of scrubber condensing water vapor and cleaning the flue gas (wet economizer, WE). An example of the first type is the installation presented in Fig. 9.1.
