    摘要: A pre-startup control method for a boiler or water heater includes: providing a controller operatively coupled to a boiler or water heater unit; performing a unit shutdown operation; enabling a pre-start up mode; at about a same time or in any order, moving an air fuel valve by a controller to a non-off position with a gas supply to the water heater or boiler turned off, wherein the controller turns on a blower at an operational level, and causes an ignitor to spark; and displaying parameters which allow an affirmation of a safe and reliable ignition prior to a gas turn on of the boiler or water heater unit. A flow balancing method and a programmed auto run method are also described.

    摘要: A boiler control system for efficiently controlling the operation of a packaged boiler is provided. The system includes a combustion air control system, a fuel control system, a flue gas sensing system, and a boiler controller. The boiler controller is in operative communication with the combustion air control system, fuel control system, and the flue gas sensing system. Based upon a system demand, the boiler controller controls coarse-level operation of the combustion air control system and the fuel control system. The flue gas sensing system may include an oxygen sensor and a flue gas differential sensor to sense a change in a characteristic of the flue gas. When the flue gas differential sensor senses a change in the flue gas characteristic that meets a flue gas differential setpoint, the boiler controller controls the fine-level operation of the boiler.

    摘要: The invention relates to a process for operating a continuous steam generator. The aim of the invention is to provide, with little technical complexity and for any operating state, a synchronous variation of the feed-water mass flow passing through the evaporator heating surface and of the heat input into the evaporator heating surface. To this end, a regulating device for the discharge of feed-water is allocated to a device for adjusting the feed-water mass flow. The control variable of said regulating device is the feed-water mass flow, while its set-point value in relation to the feed-water mass flow depends on the set-point value associated to the power of the steam generator. The actual value of the feed-water density at the entry of the pre-heater is fed to the regulating device for the discharge of feed-water as one of the input values.

    摘要: A water heater performance monitoring device for monitoring whether a water heater is functioning optimally or whether it requires service. The device uses maximum heating rates taken from a plurality of measured heating rates to determine if the performance of the water heater has degraded from a threshold performance level. A water heater performance monitoring device can reduce the number of false alarms that occur regarding the need for water heater service by filtering out temporary factors, lasting less than a time cycle, which affect heating rate of water in the water heater. This can save users time and money by reducing unnecessary water heater inspections.
