4.3 HEAT EXCHANGER

4.3.1 Inspecting the Heat Exchanger

To check the scale buildup, periodically inspect the tube having the highest temperature as follows:

1.Open the drain valve on the left side of the heater.

2.Remove the hex-head plug located on the right side of the heater under the in/out header (see Figure 34). Perform this inspection after 60 days of and after 120 days of operation. This will establish a regular inspection routine.

4.3.2 Cleaning the Heat Exchanger

An inspection and cleaning of the complete heat exchanger can only be done by removing it from the heater.

1.To remove the heat exchanger, refer to Section 2.6.1.

Caution

Black carbon soot buildup on a dirty heat exchanger can be ignited by a random spark or flame. To prevent this happening, dampen the soot deposits with a wet brush or fine water spray before servicing the heat exchanger.

2.Remove the heat baffles and check for a light accumulation of soot or corrosion on the outside of the heat exchanger tubes.

NOTE: While the heat exchanger is out of the heater, inspect the firewall refractory insulation blocks for cracks, wear, and breakage. Replace if necessary.

3.Use a wire brush to remove soot and loose scale from the heat exchanger. Do not use water or compressed air for cleaning.

NOTE: Use only the correct carbide tipped reamers which are available from Bradford White.

4.Ream the insides of the tubes (see Figure 35).

5.Pull the reamer out frequently to remove lime powder and prevent the drill from binding in the tube.

6.Install new gaskets. Do not reuse the old ones.

7.Tighten the header bolts progressively, starting with the two center bolts. Maximum torque is 20 inch pounds (27 Nm). Do not over-torque.
