- Fire - tube boiler
- Standard test method for combustible properties of treated wood by the fire - tube apparatus
- Present the experimental research carried out on strain and stress by applying the resistance strain surveying technique to the big hole sealed heads in the new fire - tube heating boilers with the laws of strain and stress distribution obtained and allowable working pressure given because there is no applicable standards or specification for calculating the strength of crude oil heating boiler heads perforated by densely distributed big - holes , which , to a certain extent , hampered the further development of crude oil heating boilers in china , and concludes from experimental results that strain and the stress of circumference are fairly large near the edge of big - hole , and the cross ribs enhance strength of sealed head to a certain degree
