Steam engine from the North Caucasus

A special section just for steam engines and boilers, as without these you may as well fit a sail.

Does that receiver pipe have provisions for heat expansion?
Perhaps that is not required?
Looks good, though.

Hi! Dear RNoe, your question is correct. The minimum possibility of thermal expansion of tht receiver is provided for by its construction on threaded connections. I hope this expansion will be quite insignificant. The steam temperature in it is not more than 150 degrees C/

Dear forum participants. I need your advice. What area should be the condenser (condenser) of a traditional design for my steam engine. The structure is something like this. The diameter of the copper cylinder is exactly 10 inches - 254 mm by inner diameter. Cylinder length 18-18.5 inches. The number of copper tubes with a diameter of 10 mm - 112 pieces, 17 inches long. Photos of the manufacture of the capacitor (condenser) and its approximate design are attached. I will wait for the assessments of my capacitor (condenser) project, which i have already begun to manufacture. Ingvar.

Please, kindly note that the previous photos show that not all the tubes are installed, but this is a matter of time. Also, please, find attached the photos of the body of condenser (copper tube). It was cold in the garage in winter, so I did the condenser when it got warmer.

Beautiful work Ingvar. I think the rule of thumb for cooling surface in an inboard condenser is 1 square foot/indicated horsepower... I don't have my metric calculator to convert, I apologize. Will you be using a circulating pump for the cooling water? Obviously the cooler the circulating water, the more efficient the condenser.

TahoeSteam thank you for your reply!
I don’t know how much power my steam engine can develop (in horsepower) at a steam pressure of 10-11 atm (kg per centimeter squared). That's why I ask the question. Presumably, the boiler I'm going to make will produce 250 kg of steam at the specified pressure. The difficulty is that the cylinder-piston mechanism is heavy, and power will be wasted to activate it. The condenser will have 2 strokes of coolant (water). In this case, the pump that will supply water will have to have a capacity of at least 80-100 liters of water per minute. This will also require power that I can't calculate. This is my question.
Thank you in advance. Ingvar.

This is a photo of the condenser cover, which is made from a 3 mm thick copper sheet. So far I have only made four caps.
I also intend to make a fifth - medium one, for rigidity.

Hello,

Unfortunately I'm a bit of a dunce when it comes to metric measurements, so I might not be the best help with figuring it out... I'll try to give it a go at converting, then converting back perhaps haha.

Did you make that roll form yourself?
