pressure boilers to pre heated water - Bing 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, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a
Watts Pre-Charged Non-Potable Water Expansion Tank-ETX-15 . With a maximum working pressure of 60 psi, the Watts ET15 Pre-Charged Non-Potable Water Expansion Tank is designed to absorb the increased volume of water created when a hot water boiler is heated.

In low water conditions, the boiler does not receive the amount of feedwater needed to keep it running at safe conditions. Because water acts as a cooling agent inside boilers, low water levels inside the boiler cause the pressure in the boiler to rise. The water absorbs heat created through combustion and turns it …
Wilson Hot Water have a range of solar pre heat gas or electric boosted hot water systems to suit your requirements or specifications. Wilson can offer flat panel or evacuated tube solar thermal hot water panels and a range of tank or floor mounted boilers to suit any application.
Instantaneous electric water heaters deliver hot water directly at the point of use. All ‘A’ rated for energy efficiency, there is no requirement to draw pre-heated water from a centrally stored cylinder, meaning heat losses are eliminated – reducing energy waste and saving on electricity usage.
High-temperature hot water boilers operate at pressures of up to 500 psig, although the usual range is 35-350 psig. System pressure must be maintained above the saturation pressure of the heated water to maintain a liquid state. The most common way to do this is to pressurize the system with nitrogen. Normally, the makeup is of good quality (e

· PDF filethat is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore used to drive turbines, since water droplets can severely damage turbine blades. Cool water at the bottom of the steam drum returns to the feed water drum via large-bore 'down comer tubes', where it pre-heats the feed water supply.
Once the boiler begins to heat water, the heated water expands and causes the pressure gauge to increase. With an in-built pressure relief valve, boilers are well-set to control these quick leaps in pressure so you don’t need to worry if the boiler shows an higher pressure than you expected when you are both using the central heating and running hot water.
The air pocket is squashed and its pressure rises to match the water pressure. As the system is heated up, the water expands and more water is pushed into the expansion vessel. The diaphragm is pushed further into the air side, squashing the air pocket a little more and the boiler pressure rises.
How to Set Hot Water or Steam Heating System Pressure & Temperature. In a closed system the expansion of water as it is heated will increase the system pressure. useful for determining the age of heating boilers, furnaces, water heaters is provided by Carson Dunlop,
This is because combi boilers heat water directly from the mains water supply and don't have a tank; solar water-heating systems supply warm, low-pressure water. Some new combi boilers do accept pre-heated water, so check with the manufacturer. To find out which boilers are the most reliable, take a look at our boiler reviews. Get A Quote
