Hello guys, I m using 8t/h natural gas fired boiler with echo flame burner(Italy) . I m facing problems with its electro hydraulic valve mounted on gas train assembly. This is modulating type burner and valve is SKP70 type. We are unable to adjust the valve at start up , once the boiler starts...

I m lokking to install a small wind turbine at my home on experimental basis. I m living in heavy populated city located near the open sea. Can any one help from where to start.

Hi carburized, Thanks for the tip. Now I feel confidant about reassembly of any planet gear. To further clarify if the Rim gear teeths are 500 and then add the number of teeth in sun gear let assume 100 . now total number is 600 and assuming 3 planet gears are there, mean 600/3 is an even...

Hi pmover, Thanks for ur reply, ur suggestion regarding the type of compressor is not very help full as we already have vane type which was cheaper and suitable for the flow we require. Any way many thanks for the adresses , Bye

hi bevnkt, Thanks for ur valued information regarding my thread. I am fully agreed with ur defination for safety and relief valve. For reversing system of marine engines i need some more detail. U are right about negative and positive cam in sulzer and B&w engines but I need some litrature...

Hi gearmanPE, I wonder if there is any bench mark on pplanet and sun gear wich should took care off during reassembly of working unit or sun and planet gears could be reassemble as it is. Kindly guide me prcisely how to reassemble a planetry gear box.

Hello friends, Why nobody is responding to me for finding vanes metarial for natural gas compressor. I found some thing but still thinking the ways to test it before using in compressor. Awaiting help. bye and happy new year

Thanks jcai, U have given me good informatios, Now i nedd to know what is stall and surge in gas turbines. i need simple answer . is there any chances of this to happen in constant RPM turbines used in power plants. can some one give me schematic of constant volume gas turbines. I have read...

hi 2081940 example for lost motion reversing system is like in GBE B&W engines where after receiving reversing order came shaft moves few degree against the new direction of rotation of the engine. This backward movement of came alter the timing of fuel pump. Axial shiting of starting came...

Back in 1995 when I was studing for my first class M.O.T , I came accross some questions for which not precise answers were avialables in marine books. One of that was about Reversing system. Tyopicaly there atre two types of tis system one is Lost Motion( B&W GBE, GFC sieries)For which details...

kenvlach we don't have wwt yet but we are planning for it. We have RO plant which is used for undr ground well water.I am planning to use it for recycling the treated water after treatment plnt we are looking for. The limitation is that biological and physio chemical treatment plants does nt...

Thanks for all who respond to my thread, Speco you are some what correct assuming that this conversion is for gas flow. but it it from normal cubic meter to normal cubic feet. i further explain , We have gas flow meter installed provided by gas company. The meters are with pressure and...

kanvlach, i would like to use water again from waste nothing else. For well water u understood correct it is 7500 ppm tds. R.O we are using to purify the water up to 200 tds and less then 17.5 ppm hardness. Same RO i planed to utilise for recycling the waste water.(After color and other things...

Compositepro, Thanks for ur response. If u could provide me more details about air plane turbines fuel consumption, power produce / thrust produce efficiency or could give me address of any web site for these information. thanks again

hi, I have very simple question what is the conversion factor for converting m3 to cubic feet. is 1 cubic meeter is equals to 35.31 cubic feet. is there any pressure and temprature adjustment is needed in this factor. bye

hello guys, I have solar gas turbines reaching 30000 hrs. its unit exchange will be due after 30000 hrs. I need adresses of some reputable companies dealing with solar turbines maintenance. I have contact with one who supplied us the package but i need some more companies in order to prepare...

Hi , could any one suggest the best available technique t treat textile waste fro dueing and printing and make it recycleable to the process again. I have RO plant available working on well water of 7500 tds. quantity of waste water is 500000 GPD. awaiting response. bye
