What does it mean when the Room fills with smoke whenever you burn wood in fireplace?
Something is preventing your fireplace from drawing. The damper may be closed, or partially closed. Your chimney may have a blockage, or you may have prevailing winds that push smoke back down the chimney. If you have air flow problems, such as a vent fan that draws air out of the house, it can cause that. Bottom line- if the damper is open, and the flue is not blocked, you need a good fireplace/chimney specialist to examine what you have.
How do you know when your fireplace chimney needs to be cleaned?
If a fireplace is only being used once a week or for only a few hours at a time, it is necessary to only have a cleaning once evey two to three years. However, if there is soot coming down when opening and closing the damper, this is a good determining factor that the fireplace/chimney is in need of cleaning.
How do you clean wood charcoal stains off a porous concrete fireplace hearth?
We had carbon on the stone above our fireplace opening because a guest at our cabin started a fire without opening the damper. We used Sure Klean Fireplace Cleaner, following the instructions on the bottle. It's not easy to find, but it works as advertised. It removed all the carbon from the stone. The grout is 90% cleaner, but if you know to look, you can see that the grout is ever so slightly darker than the grout on the side of the fireplace, where there was no smoke damage. I give this product 5 out of 5 stars.
Why should you never look into a container that is being heated?
The material in the test tube could become super heated, bubble over, or explode, depending on what it is. If you were pointing the test tube at yourself or someone else, the material could shoot out of the test tube and burn your face or the other person's face. As a former chemistry teacher, I have seen this happen, despite my many warnings. This is why you also need to wear goggles and a lab apron.

Difference between photohelic and magnahelic guage?
PHOTOHELIC® Pressure ControlPHOTOHELIC® models combine the MAGNEHELIC®gauge with a precise pressure switch that lets you control low and high gas pressures. Knob controls adjust dual set points, which allow for variable deadband control. These set points contain photocells that actuate DPDT relays when room pressures reach a preset upper or lower limit, and they can be set up to control corrective damper action. As the room pressure changes in response to damper motion, and the indicator returns to the null band, damper motion is halted.

What is a Louvre damper?
A Louvre damper is a flu-gas flow control device, analogous to a Venetian blind, that fits between a furnace's flu gas outlet and its chimney; operation of an external lever causes the slats to rotate up to 90 degrees in unison as the damper moves from fully opened to fully closed and visa versa.
What is the difference between smoke damper and firesmoke damper?
Assuming your question relates to life safety in building construction, and not to parts of a wood burning device- Smoke dampers are intended to limit the movement of smoke within a building, or section of a building. They are not intended to inhibit FLAME spread. A fire damper will inhibit smoke movement, but is also insulated to stop fire. A simple smoke damper might be light weight sheet metal- but that is not enough to stop very high temprature. A fire damper is heavier, may be insulated, built of fire resistive material, etc.
