In the context of chemistry, this is likely to refer to a type of burner. The difference between a Bunsen burner and a Tirrill burner has to do with how the air flow is regulated ... a Bunsen burner usually has slits at the base of the barrel to admit air, while in a Tirrill burner the airflow is controlled by means of a needle valve.
Burners in a real chemistry lab are actually more likely to be of the Tirrill type than the Bunsen type, since the needle valve allows better regulation of the air-gas mixture and therefore a steadier more reliable flame. There are some other modifications as well (the most common one being the Meker, which is the one with the "big head" that has a grid inside it, which spreads the heat more evenly). I've also seen a kind with horizontal slits where incoming air is regulated by screwing the entire barrel up and down (this is less common, as the barrel may become uncomfortably warm to touch, though it usually takes some time for this to happen and the adjustment of the air/gas mix usually happens immediately after the burner is ignited). I don't know if that type has an official name, or if so what it is.

Who invented the Tirrill Burner?
Francis Preston Venable in 1887.
Different kinds of burner?
Three types of laboratory burners are the Tirrill Burner, Bunsen Burner, and the Meker Burner. The Tirrill and Meker Burner have air and gas adjustments while the Bunsen Burner has only an air adjustment. Hope that helps.
What are the 7 parts of the tirrill burner?
A tirrill burner has a barrel, air vents, gas inlet and needle valve. The barrel turns on a threaded mount to allow air; the air vents limit the air entry into the barrel; the gas inlet is where the gas flows; and the needle valve regulates the gas flow.
What is used to heat up large amounts of liquid in a science lab?
Large amounts of liquid are heated in a boiler or a vat. A boiler heats water to produce steam for heating buildings. A vat is used in a factory to heat large amounts of liquid for many different purposes.
What makes the flame of the tirrill burner luminous?
Luminous flames are formed when the energy released is at a certain part of the electromagnetic spectrum. A red flame is given off when the energy is at the same energy and wavelength of red light. A yellow sooty flame is much lower energy and caused by a lack of oxygen. Burning fuels produce heat. Heated atoms and/or molecules emit a photon as they return to a lower energy state. Look at various flames, You may see concentric areas that are like layers, each one a different color. The fuel breaks up or is oxidized differently in each layer and each has a distinct temperature and chemical makeup. Not all emitted light from a flame is visible, a lot is emitted in the infrared spectrum which we cannot see but will feel as it heats our skin. Some flames are totally invisible, like from hydrogen. Some emitted light is only at very specific (narrow) frequencies, which we will see as certain colors, light and dark blue from methane premixed with air in a Bunsen burner or stove-top gas range. Hot carbon atoms emit over a very wide range of frequencies at random, so we see yellow light from candles. If hot enough, carbon emits a bluish white light, like from acetylene/oxygen.
