black prepersitation formed in fire tube boiler

Records of Steam Boiler Explosions, by Edward Bindon

This boiler has been found to generate steam very rapidly; but the extreme weakness of the construction over the fire and along the tube, especially at the part where the front end of the tube widens out in a bell mouth to meet the wagon-topped fireplace, has led to so many explosions that few boilers are now made of this form.

Risks from redundant solid fuel back boilers

Risks from redundant solid fuel back boilers . The redundant solid fuel back boiler had been left in a sealed condition and sometime later, when a coal or wood fire was lit in front of the boiler, the unit heated up sufficiently for the internal pressure to cause the boiler casing to explode.

US4659305A - Flue gas recirculation system for fire tube

A flue gas recirculation system for fire tube boilers includes a duct connected to the boiler gas discharge stack and to a fan. Another duct couples the fan to a specially designed burner in the boiler. Recirculated flue gas is injected downstream of the fuel/air mixture in the burner and cools the flame leading to substantially reduce the NO x content in the boiler stack emissions.
