gas steam boiler input

[jldesign]

new brewhouse:
electric steam boiler is out not enough house power - switching gears

looking for a high pressure steam boiler:
kettle is a meura 8.5bbl high pressure
MT newlands 10bbl 15psi
HLT newlands 10bbl 15psi

anyone have good things to say or contact info for something that can fit our bill. thinking 600k btu would be plenty. would rather work with a brewery friendly company for boiler,blowdown,return,etc

any help you can offer would help our ulsers out.... slainte!

Your Meura kettle dictates that you get a high pressure boiler. High pressure surface areas are much smaller than low pressure. Then your low pressure tuns will require some sort of pressure regulation to be below 1 bar. Mixed equipment will make your installation more complicated. Best bet is to contract a good steam guy. 600kBTU is more than enough. Even 500kBTU should do well. Your mash schedule will dictate heat rate. Work backwards from your mash schedule. Your biggest load will likely be your kettle as the mash runs off. Good luck!

Don't know what your location is but in many states/provinces/countries, if you want to operate a high pressure (>15 psi) steam boiler, you will require a stationary engineer on-site and on staff. This can be expensive for a small company (unless one of the principals happens to be said engineer)

Used high pressure vessels can also be expensive and time consuming to certify as well as having large insurance and insulation cost implications.

We operate a 10 hL kettle built by Miyake of Japan but designed by Ziemann. It is a high pressure design with jackets and an internal calandria. We operate it and our HLT (also a high pressure vessel) on low pressure steam.

We have had no issues at all. We get great boils, evaporative rates, heating rates etc.

You may want to speak with a brewery engineer.

yes we learned all about the costs with high pressure - on site tech, locations, firedoors, insurance costs - our plan is runnign it low pressure as it is basically a kettle surrounded completely with jackets. good to hear others are using low pressure as well. thanks everyone for the comments.
