A heat exchanger cleaning system is disclosed which is capable of determining the position of a lance within a tube bundle of a heat exchanger core. The system comprises a lance for directing a jet of fluid into spaces between the tubes of the bundle, an arm mounted alongside the lance and movable relative thereto, an abutment mounted to an end of the arm to sense an outer surface of the heat exchanger core, and a transducer for measuring the position of the lance relative to the arm to determine the extent of travel of the tip of the lance beyond the front face of the tube bundle.

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.

The present disclosure relates to a method for predicting a slagging production position and a slagging production possibility in a furnace, the method including: the analyzing step of analyzing physical compositions of two or more kinds of coal; the phase diagram producing step of producing a phase diagram on the basis of the physical components of the two or more kinds of coal analyzed in the analyzing step; the deriving step of simulating the situation generated when the two or more kinds of coal are co-fired on the basis of the produced phase diagram; and the characteristic analyzing step of analyzing the characteristics in the furnace in the co-firing process of the two or more kinds of coal.

The present invention is directed to systems and methods for cleaning a component inside a machine, such as an evaporator coil inside an air conditioner. A pump is connected to a controlling device. The pump is also connected to a metering device. The metering device is connected to one or more reservoirs. The metering device is also connected to one or more wands. Each wand is positioned inside a housing containing the component to spray cleaning solution, drawn from the reservoirs by the metering device, onto a face of the component. To perform the cleaning of the component, the controlling device disables the machine. The controlling device then activates the pump. The pump causes cleaning solution to be drawn from the one or more reservoirs into the metering device, which then transfers the cleaning solution into the wands. The controlling device then allows the machine to resume operation.
