8 Thermal Efficiency Three Pass Hot Water Boiler

The typical "pin type" boiler is a single pass design, with a mass weight of cast iron and water in excess of 650#, and a chamber flue pass age length of approximately 2.5 -3 . The bottom line is that boiler design is in reality simple physics, and this tells us that the larger the mass, the more Btu s you need, and therefore, the more fuel

This series Oil Gas Fired Hot Water Boiler is horizontal type fire tube boiler with three pass structure, it has compact structure, small volume, strong load adaptability and low water quality requirement. This boiler adopts wet wet back structure, it can adapt to the high temperature, has a good sealing, increase the radiation heat transfer area and improve the heat transfer efficiency

Packaged Boiler: Intech Boiler. Intech as it’s name implies is a 3 Pass Internal Furnace Packaged Boiler.It is a conventional 3 pass smoke-tube design, designed for the combustion of coal and wood in an internal furnace and is therefore sometimes known as coal/wood fired Steam Boiler.. This Packaged Boiler comes in dry back, semi-wet back, and fully wet-back options and is most suitable for

Figures 3.2.1a and 3.2.1b show a typical two-pass boiler configuration. Figure 3.2.1a shows a dry back boiler where the hot gases are reversed by a refractory lined chamber on the outer plating of the boiler. Figure 3.2.1b shows a more efficient method of reversing the hot gases through a …

Buderus developed a full three-pass system which increases the efficiency of the boilers. With single-pass boilers, the flue products have only one chance to heat the water. Buderus three-pass boilers triple this opportunity. The unique way heat flows through the G115 and G215 boilers allows the water to be heated three separate times.

Gas/oil fired thermal oil boiler. Thermal oil boiler burning gas or oil, also widely used for heating/drying/dyeing processing, the oil temperature up to 350°C at specific pressure, hot oil circulating from boiler to tank to equipment use, higher thermal efficiency.

Introduction of Coal Fired Hot Water Boiler: These two models hot water package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface,while the drum and the water walls on both sides from a radiation heating

High efficiency. Such series boiler adopts three pass structure and wet back reversal chamber structure. Besides, it uses high-quality aluminum silicate to preserve heat to make the heat loss of the machine fall down to limit value and the overall thermal efficiency up to 92%.
