Since a welding symbol specifies welding of only the joint to which an arrow is pointing, and a change of direction or change in geometry constitutes the end of a joint, a multiple arrow welding symbol can be very helpful, particularly around closed corners (Figure 2). FIGURE 2. The Reference Line.

In shell boilers with a working pressure of between 7 and 17 bar the temperature of the mass of water in the boiler is typically in the range of 170–210 C. Allowing for, say a temperature difference of 30–50°C between the exhaust gases and the water temperature, the boiler exit gas temperature cannot be economically reduced beneath about 200–260°C, dependent on the operating pressure.

2021/5/4 · Hot water is piped through it from a gas central heating boiler, giving up some of its heat to the air in the room in the process and returning to the boiler for more. This is a sort of heat exchanger because the heat from one fluid (the hot water in the pipe) is being given to another fluid (the cold air in the room) without the two fluids mixing.
