A system for improving a steam oil ratio (SOR) includes a direct steam generator (DSG) boiler fluidly coupled with a downhole portion of a steam system via at least a DSG outlet, wherein the DSG boiler is configured to schedule super-heat delivered to the downhole portion to optimize the SOR associated with the system

Disclosed herein is a method of automatically cleaning boiler pipes. The provision of a pipe-cleaning tank on one side of a casing to store a cleaning solution therein and a tank supply valve in the pipe-cleaning tank allows the cleaning solution stored in the pipe-cleaning tank to automatically flow into a heat exchanger and various pipes inside the casing by means of only a simple operation of manipulating the tank supply valve, thereby making it easy to eliminate scale that has accumulated in the heat exchanger and the pipes.

Methods and systems for cleaning inner surfaces of tubes in a heat exchanger. Some systems include a cleaning device having a nozzle configured to inject cleaning fluid into first and second tubes to perform different first and second cleaning cycles on the tubes, respectively, a controller configured to determine delivery parameters for the cleaning cycles based on a characteristic of each tube, and to control the cleaning device to perform the cleaning cycles based on the delivery parameters. Some methods include determining, with a controller, a tube in the heat exchanger engaged with a nozzle of a cleaning device for injecting a cleaning fluid into the tube during a cleaning cycle, a characteristic of the tube, and a delivery parameter of the cleaning cycle for the tube based on the characteristic of the tube; and performing the cleaning cycle for the tube based on the delivery parameter.

The following provides a system and method to predict an indicator of tube fouling in a fired apparatus such as a boiler. Historical data can be collected when the tubing is still considered to be clean, and used to build a first model between an indicator of fouling, such as tube skin temperature, and boiler load. The actual measurement of that indicator of fouling can then be compared against the model output, such that the error between the model and measurement is considered an indication of the tube fouling. Moreover, the rate of change of the model error can be used to measure the fouling rate. Next, historical data on the fluid feed quality can be collected and together with the historical error rate change data can be combined to develop a second model. This second model reflects how fluid feed quality variables may affect the fouling rate over time.
