fire tube boiler design for dry back reversal chamber

Molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.

Technical advantages

Digitized manufacture

  • The laying-off of steel tube adopts CNC 3D laser cutting machine.
  • The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.
  • The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.

Long life span

  • The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;
  • Convection section: optimize convection heating surface and adopt effective fix and structural support to make its working life longer.
  • Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.

Less fuel consumption

  • Use superior refractory brick to build inside and superior perlite in the middle. Keep the furnace temperature under 50℃ to make the minimization of loss.
  • Furnace adopts double close line coil, which makes heating surface sufficient.

The combustion chamber can be outside the boiler shell and refractory-lined (designated dry-back), within the shell and entirely water-cooled (wet-back) or a combination of the two (semi wet-back). These three basic configurations are illustrated in Figure 8 .

Fire-tube boiler - Wikiped

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction , heating the water and ultimately creating steam .

Wet-back Fire Tube Boiler for Sale--Z

Wet-back Fire Tube Boiler for Sale 2018-08-14 11:15:37. The two most commonly types of boilers are the dry and wet back. Wet back have steadily become more popular option as they are considerably more efficient and require far less maintenance. The term ‘wet back’ comes from the fact that the reversal chamber is completely surrounded by water.

Dry back boiler configuration; Wet back boiler configuration; The above mentioned two-pass boiler configuration types are shown in the figure below. In the first configuration i.e. dry back boiler configuration, the reversal of hot combustion gases is done via a refractory lined chamber located at the external covering of the boiler.

There is a variety of boiler design concepts available in the marketplace. The material contained in this guide wall-combustion chamber. A burner system, boiler and burner controls are then piped and/or wired into the assembly at the job site. Boilers are available as dry back or wet back (water cooled gas reversal area). The popular

Paxman History Pages - Boile

The Economic Boiler. A return-tube, dry-back shell boiler, the Economic was introduced by James Paxman in 1875. Its design was a major advance on the two main types of shell boiler in use at that time, the Cornish and the Lancashire.

Fire Tube Boiler Design Software - firecad.n

In Fire tube boilers, water is contained in a shell and hot gases pass through the tubes. Burners are provided to fire the fuel inside the furnace. In case of solid fuels, stationery or movable chain grates are provided inside the furnace. Fire tube boilers can be either wet back or dry back.

Wetback vs Dryback firetube boiler desi

The dryback boiler reversal chamber has a rear wall that is lined, or jacketed with refractory, which passes combustion gasses from the furnace to multiple tube sheets and reflects burner heat, resulting in exterior radiation losses. The dry back boiler design uses a common rear tube sheet and features convenient fire-side and water-side access.
