How long have you been dealing with this? Today. Contractor's Assistant: Do you plan on doing the work yourself? If you want specifics I need a model number. But a rumbling noise in the exhaust usually isn't caused by a blocked heat exchanger.
tell if your heat exchanger is cracked, you will need to look for the signs. If water collects at the base of your furnace, or there’s excesses soot or strong smells coming from your furnace, it’s most likely cracked. Also, if the fire is yellow or there’s any corrosion, you most likely have a cracked exchanger.

Heat Exchanger. If you have a high- efficiency furnace (90%+) then you also have a secondary heat exchanger. The secondary heat exchanger is where the flue gas undergoes further heat exchange and water vapor forms. After exiting the primary heat exchanger, the burning gas proceeds to the secondary heat exchanger.
A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes.

A heat exchanger is a device in which energy is transferred from one fluid to another across a solid surface. Two important problems in heat exchanger analysis are (1) rating existing heat exchangers and (ii) sizing heat exchangers for a particular application.
Heat exchangers are used in a wide variety of applications, such as power production, process, chemical and food industries, electronics, environmental The heat transfer principles are the same as those of the rotating-plate regenerative air heater. In a fixed-matrix regenerator, the gas flow must
03, 2018 · One of the oldest ways to check for heat exchanger cracks is to simply observe the flame when the blower starts. Most furnaces will have a blower delay to get the furnace up to temperature before moving air over the exchanger. This procedure is as simple as watching the flame and observing if the flame moves or changes when the blower Reading Time: 5 mins
