Abstract: The improved water heater is a combustion reaction based water heating apparatus. The improved water heater is used to heat fresh water for domestic and light industrial purposes. The improved water heater includes a tank and an enhanced heating device. The insulating structure stores the water during and after the heating process. The enhanced heating device: a) contains the combustion reaction; and, b) transfers through a heat exchange mechanism the heat generated by the combustion reaction to the water contained within the insulating structure. The enhanced heating device includes a heat exchange apparatus. When compared to a traditional exhaust flue, the heat exchange apparatus more efficiently transfers heat between the heated exhaust gases from the combustion reaction and the water contained in the insulating structure.

Abstract: A cleaning system and method includes suspending and exploding, adjacent a bank of HRSG finned-tubing, a plurality of generally uniformly spaced detonation cords. Each detonation cord has an explosive grain loading of 18-50 grains per foot. A detonation delay assembly attached to each of the plurality of detonation cords creates a predetermined delay between each detonation cord explosion. After the detonation cords are exploded, a suspended elongated beam, having a transport assembly and a pressurized air blower assembly directs pressurized air towards an adjacent the bank of HRSG finned-tubing as the pressurized air blower assembly is moved along a portion of the beam. A suspension assembly moves the beam, the transport assembly, and the pressurized air blower assembly up or down so that a next portion of the bank of HRSG finned-tubing may be cleaned by the pressurized air.

Abstract: A control system is provided for a modulated heating system including a plurality of modulating water heaters, which may be modulating boilers. A deadband control scheme provides for reduced cycling of the modulating heater when total system heat demand falls between the maximum output of one heater and the sum of the maximum output of that one point and the minimum firing point of the next subsequent heater. Condensation of flue gas products is prevented by monitoring flue exhaust temperature for each heater and controlling the modulation of each heater to maintain a minimum heater output sufficiently high to prevent condensation of flue gas products from that heater. Rapid reaction to changes in system heat demand is provided by sensing changes in flow rate in a primary loop of the system and anticipating resulting changes in temperature thus allowing for change in heater output prior to the time the change in flow rate has fully impacted system temperature.
