you are required to search and calculate the boiler power required to heat a 150 litres hot water cylinder in 1 5 hours with hot 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 advantagesThe front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
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.
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.
Step 2: Calculate the required KW: [3333 SCFM x (400°F-350°F)]/3193 = 52 KW . Calculations for circulation heater applications. When calculating the power required to heat a material flowing through a circulation heater, the KW equation shown below can be applied.

Many people remain under the impression that hot water storage cylinders mean that they will run out of hot water, and therefore have to wait for the cylinder to heat up. If the cylinder is sized correctly according to the needs of the household, this should not happen. Here’s a

However this will require a much lower watt density than on a water heater. For more specific information on oil, or heat up
