The mounting system includes a laser transmitter mount configured to provide adjustment of a laser transmitter and a laser receiver mount configured to provide adjustment of a laser receiver. The mounting system also includes a laser path extending between the laser transmitter and the laser receiver that includes an entrance port in the ductwork and an exit port in the ductwork. The mounting system also includes a flexible joint in the mounting system, where the flexible joint is configured to isolate at least one of the laser transmitter and the laser receiver from movement of the ductwork.

The present disclosure deals with the detection of a blockage in the air-supply duct or flue of a burner assembly. In some embodiments, a method or system may detect blockages in the form of coverings and with burner assemblies to burn fossil fuels. For example, a control device may generate: a first air-control signal; a fuel-control signal by adjusting the actual values of the ionization current to the ionization-current setpoint; a setpoint increased by a specified amount from the ionization-current setpoint; and a changed fuel-control signal by adjusting the actual values of the ionization current to the increased setpoint in the case of a first air-control signal. The control device may evaluate the changed fuel-control signal generated based on the increased setpoint by comparing it with a specified maximum value and based on the evaluation, to detect a blockage. The control device may recognize the blockage based on the evaluation if the fuel-control signal generated using the increased setpoint exceeds the specified maximum value.

Systems and methods operate to infer a fuel composition in a combustion system. The fuel composition may be inferred by receiving measured operating parameters including one or more of fuel data defining fuel characteristics used in combustion within a heater of the combustion system, emissions data defining emission gasses exiting the heater, airflow data defining ambient air being supplied to the heater and airflow rate of the air within the heater. One or more relationships within the measured operating parameters may be identified that result in a list of potential fuel compositions. One of the potential fuel compositions from the list may be selected having sufficient likelihood of resulting in the measured operating parameters as an inferred fuel composition. The output the inferred fuel composition to a heater controller of the combustion system and used for automatic control thereof.

An apparatus for cooking, a cooking appliance monitoring system, and a method of monitoring a cooking appliance are provided. The monitoring system collects and processes signals from sensors linked to the cooking appliance.

Provided is a combustion device, including: a burner including an ammonia injection nozzle having an injection port that faces an inner space of a furnace; and an adjustment structure configured to adjust an opening area of the injection port.

A portable indirect fuel fired heater includes a burner assembly having a fuel burner to deliver fuel from a fuel supply to a combustion chamber of the heater and a combustion air blower to deliver combustion air to the combustion chamber with the fuel for combustion in the combustion chamber to produce exhaust gases. A heat exchanger receives air to be heated in heat exchanging relationship with at least a portion of the combustion chamber. A sensor senses an oxygen level as a partial pressure of oxygen in the exhaust gases. A controller operates an actuator operatively connected to the burner assembly to controllably vary the delivery rate of combustion air and thus vary the ratio of the air and fuel responsive to the oxygen level sensed by the combustion sensor so as to maintain the sensed oxygen level at a prescribed set point level stored on the controller.
