is there a relationship between the pressure and temperature rise of normal pressure boiler

Military Explosives Chapter 12

This law states that at a constant pressure a perfect gas expands 1/1273 of its volume at 0oC, for each degree of rise in temperature. Therefore, at 15oC the molecular volume of any gas is, V15 = 22.4 (1 + 15/273) = 23.63 liters per mol

Steam Boiler Costs - 2020 Buying Guide - Prices - Modernize

Steam boilers are a type of boiler that has been in use for hundreds of years around the world. The average cost for a steam boiler is about $4,000.A higher end steam boiler installation could cost up to $7500. Steam boilers rely on simple mechanics, which make them so reliable to work with.Still, they aren't particularly efficient or quiet compared to hot water boilers on the market today.

Heat Engines

where P is the pressure, V the volume and T the temperature of the gas and k is Boltzmann's constant and N is the number of molecules in the gas charge. Putting energy in the form of heat into a gas will increase its temperature, but at the same time the gas laws mean that the gas pressure or volume or both must increase in proportion.

Ventilation (architecture) - Wikipedia

Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives.
