Introduction . WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection

BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam.
The KWP type Water Tube Packaged Boiler is designed with 2 or 3 gas passes depending on the combustion gas flow rate and its thermal efficiency can be improved with the addition of the heat recovery equipments such as economizer or air preheater depending upon the clients specification. Get a Quote
Package boilers are generally of shell type with fire tube design so as to achieve high heat transfer rates by both radiation and convection. The features of package boilers are: • Small combustion space and high heat release rate resulting in faster evaporation.
When a package fire tube boiler is used as a hot water unit, what is needed? Forced circulation is required. Most common type of fire tube boiler used for heating applications. Modified scotch design. What is used to maintain high gas velocity in fire tube boilers? Throughout all passes fewer tubes are used in each successive pass.
Multiple pass boilers increase efficiency because the passes are designed to maximize flue gas velocities as the flue gas cools. Integral Boiler/Burner Package Ultimately, the performance of the boiler is based on the ability of the burner, the boiler, and the controls to work together.
