A boiler system includes a boiler having at least one heat exchanger having a surface on which a deposit may form. The boiler system further includes at least one retractable sootblower having a lance tube for carrying a high pressure fluid into the boiler. The lance tube is configured such that the high pressure fluid impacts the heat exchanger surface to effect a vibration in the boiler system. The boiler system also includes at least one vibration measuring device coupled to the boiler system. The vibration measuring device is configured to measure the vibration in the boiler system, and the measured vibration indicates presence or absence of the deposit on the heat exchanger surface. The vibration measuring device may optionally detect a vibration caused by the release of the deposit from the surface of the heat exchanger or the impact of the released deposit with a surface in the boiler system.

A process for augmenting energy in a dryer used in processing is disclosed. The process includes providing a source of syrup having concentrated solids. They syrup is then directed through a syrup line to a recirculation pump where it is recirculated to a heat exchanger having a source of heat delivered thereto. The syrup is heated to a temperature above a flash point of the syrup. The heated syrup is delivered to a flash tank and water vapor is flashed off and then directed through a vent and into a dryer. Cooled water remaining in the flash tank is delivered through a cooled liquid line to the syrup line to repeat the process. The delivery of water vapor to the dryer results in an additional source of energy being transferred to the dryer.

A data logger device for monitoring operation of a flexible lance drive apparatus is disclosed that includes a cylindrical housing removably connected to an air fluid pressure line to the drive apparatus, a circuit board mounted in the housing, a pressure sensing switch mounted on the circuit board and communicating with the fluid in the pressure line, and a processor and memory on the board operable to log time at which the switch changes state between two predetermined states.

The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

A high temperature fluid generator is configured to heat a fluid (e.g. water; thermal oil or the like) to a high temperature (e.g. greater than 250 degrees Fahrenheit or 120 degrees Celsius) using a fuel-burning furnace. The generator generally comprises a furnace module, wherein fuel is burned, and a convection module where the combustion gases are put in contact with a series of fluid-bearing convection tubes. The furnace module comprises a series of fluidly interconnected headers, some of which are also fluidly connected to the convection tubes in the convection modules. The various headers contribute to the overall structure of the generator. The convection tubes are arranged into at least two bundles which are movably mounted in the convection module of the generator such to be movable in and out of the convection module for inspection, cleaning, maintenance and/or repair.
