Introduction. Fire tube boilers, also known as smoke tube boilers, are the most common type of industrial boiler employed today. Compared to water tube boilers, they are much more suitable for smaller plant applications because they can better cope with sudden high demand steam fluctuations.. Combustion occurs within a furnace with the exhaust gasses (flue-gasses) passing through a series of Learn More

1 The critical pressure gives the velocity of steam at the throat equal to the velocity of sound; 2 The flow in the convergent portion of the nozzle is subsonic; 3 The flow in the divergent portion of the nozzle is supersonic; 4 To increase the velocity of steam above sonic velocity (supersonic) by expanding steam below the critical pressure, the divergent portion for the nozzle is not necessaryLearn More
The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers.Learn More
Apr 01, 2016 · Existing boilers that burn CTRTs must have been designed to burn both fuel oil and biomass (see Figure 3, page 37). CTRTs can be burned in boilers at major pulp and paper mills and at power production facilities subject to the Boiler MACT rule only if the boilers were previously designed to burn biomass, fuel oil, and coal but were modified (e Learn More

95 percent are required. When applied to wood-fired boilers, ESPs are often used downstream of mechanical collector precleaners which remove larger-sized particles. Collection efficiencies of 93 to 99.8 percent for PM have been observed for ESPs operating on wood-fired boilers. A variation of the ESP is the electrostatic gravel bed filter.Learn More
Which of the following componets used in a combination heating system employing a water heater is required to prevent thermo siphoning from the heating loop. In a fire tube boiler the water surrounds the tube. True. A pool heater will not shut off on the operating control. The most likely cause is defective circulating pump.Learn More
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.Learn More
