  1. ok i am beginning to understand the safety interlocks and controls which is what i wanted to reuse are probably not going to work it is a glow plug ignitor so that is probably out as well i may be able to use the blower and possibly tne regulator the stainless tank may be reworked into a shell and insulate it thanks for the comments and help i will think on it some and when the fall comes i may take it apart and see what i have to work with
  2. sorry i missed some of the discussions this is a pool heater designed to heat a 10,000 gallon pool it is 400,000 btu per the model and verified at the web site it is a high efficiency burner with a blower motor on top of the boiler. i know that when it went in they had to put in a bigger gas regulator on tne house to keep up with it the line going across the yard is 1-1/2 inches it drops down at the heater i was planning on gutting everything insulat it replace the burner tube with a ribbon burner to avoid problems with increases temps basically i have a control system with ignitor, safety interlocks, and a fan blown burner. but i am asking and a the consensus is bad idea not sure why more specifics please on why bad idea so far the one that makes since is that 400,000 but is just to big the problem of the heating coils going bad is common there is a pool maint guy in the building i work in. i may have hil keep an eye out on a smaller unit in tbe 100,000 to 200,000 btu range that is beginning to make since thanks
  3. natural gas connected to house gas meter the heater has the regulator, igniter, fan for the burner, and all safety interlocks. those are the reasons i want to repurpose it. all safety interlocks and a fan and burner tube assembly sized to match
  4. i could very easily have tne gas line wrong i know that it is 400,000 btu i will try to read up and see if i can modulate the burner the boiler area is 24 inches in dia (from what i remember) and about a foot tall i know that tne exhaust is hot but not to bad, so i assume that the combustion is complete inside tne combustion tube the top is held on by a clamp to make it water tight, so i could use the top flange as the top of the forge and build a new insulated box for the forge making it as tall as i need to get the flame where i need it if the burner is to big what options do i have to reduce it: can i put in a smaller orifice on the gas line and then put an adjustable opening on the fan to adjust the air flow? i would then plan on making a ribbon burner i need to read up on the design to build a mixing chamber
  5. So I have an idea for a forge. I have a 400,000 BTU natural gas heater for my pool that had the heat exchange develop a leak. I rarely use it so it is not worth fixing it. It has a ¾ inch natural gas supply and the heat ex changer is stainless steel. It has a blower unit for the flame, and there is a “flame tube” in the assembly drawing. (item 11), I am thinking of making it into a forge. Take the front plastic panel off, but keep the rest to keep it weather tight. I will make the front panel so I can take it off to use the forge, but drop it back in to keep it weather tight. Take out the heat exchanger and use the opening for the door. I have some fire brick to use for a door. I have a Kilm shelf that I can use for the floor and top (just because I have and and do not want to spend money unless it works) I have extra light fire brick that I got from a kilm manufacturer when I was there for a class on kilm repair that can use for the walls I will keep the existing exhaust setup. (it is already balanced to the blower) I might replace the flame tube with a ribon burner. (item 11 in the parts break down below) But for the first firing I can use the existing flame tube. I will keep the existing controls including the self igniter, and gas control valve. I will just put the thermo couple that normally measures the water heat in the air (or a glass of cool water) and I can use the control to turn the burner on and off. I could try to rewire it to a switch, but the existing controls already turn on the ignitor and have the safety interlocks built in, so it is pretty easy to reuse them. I will build a stand to move it up to a comfortable level. I may reuse the outside cabinet, just to keep it weather tight,. (since I do not have a shed built yet) In reality it will be a year before I get around to it, it is already 100F here in Texas, to hot to get a forge going right now. And I have other projects to get done first. A basic newbe question. If I want to replace the flame tube with a ribbon burner, I assume I need to keep the area of the holes for the ribbons equale to the area of the existing tube so the blower and flame front are balanced. Is that correct? Any other pointers for the ribbon burner design? I have not taken it apart yet but from the general size of things, I assume that the flame tube is about 4 inches in diameter. The outside housing (which is stainless steel) is about 24 inches in diameter. (rough guess. I did not measure it) Am I wasting my time on this, or does it have possibilities? .
