摘要:
The invention is in the field of boiler control and relates to a control method for the operation of a combustion boiler, comprising providing a predetermined upper limit (V F,max ) for the flue gas velocity in at least one location of the boiler; monitoring the flue gas velocity (V F ) during the combustion of fuel in said at least one location of the boiler; comparing the flue gas velocity(V F ) with the predetermined upper limit (V F,max ); decreasing the thermal load of the boiler if the flue gas velocity exceeds the predetermined upper limit (V F,max ). The invention also relates to a control system configured to execute the control method.
摘要:
A pressure probe assembly for attachment to a venturi of a gas-fired appliance, where the venturi includes a body having an inlet end, an outlet end, and a wall defining a mixing chamber extending from the inlet end to the outlet end about an axis. A support member is detachably coupled to the mixing chamber. A first pressure probe is coupled to the support member and has a first pressure tap disposed substantially adjacent the axis. A second pressure probe is coupled to the support member and has a second pressure tap disposed substantially adjacent the mixing chamber wall. Also disclosed is a gas-fired appliance, such as a water heater, including the pressure probe assembly.

A boiler (1), in which the secondary air temperature can be efficiently increased for higher thermal efficiency by appropriately reducing the heat transfer area of the boiler while maintaining the heat collection of steam in the whole boiler, is disclosed. In the boiler, a heat exchanger (16, 17) provided in one of two flow paths formed by partitioning a downstream portion of a flow path for exhaust gas discharged from a furnace (23) has a smaller total heat transfer area than a heat exchanger (20) provided in the other of the two flow paths; the exhaust gases discharged from the flow paths to outside the boiler (1) are introduced, without being mixed, into an air heater (2) downstream of the boiler (1); and, in the air heater (2), the heat of the exhaust gases is transferred to the primary air and the secondary air so as to heat combustion air.
摘要:
A method is provided for managing an amount of energy utilized by a carbon dioxide capture system. The method includes providing a fuel and a feed stream to a combustion system. The feed stream includes oxygen and a portion of a flue gas stream generated upon combustion of the fuel. The method also includes subjecting the flue gas stream to a carbon dioxide capture system to remove carbon dioxide therefrom, measuring a concentration of oxygen present in the feed stream, and selectively adjusting an amount of the flue gas stream included in the feed stream based on the measured concentration of oxygen in the feed stream. The selective adjustment is performed such that the feed stream maintains an oxygen concentration in a range of between about 10% to 90% by volume and the carbon dioxide capture system operates at an energy load between 1.4 GJ/ton of carbon dioxide and 3.0 GJ/ton of carbon dioxide.
