Boilers for use in residential or small-scale buildings are known. Typically, a boiler unit houses a burner assembly arranged to ignite and bum a liquid or gaseous fuel to generate heat, which is then transferred to a heat-conveying medium, such as water, through a heat exchanger. Water heated by a boiler may be circulated through radiators of a central heating system or made available for consumer usage. In a domestic or office environment, it is advantageous for a boiler unit to also generate electricity, for powering appliances or for sale to the mains electricity grid. Typically, the boiler unit itself will use electricity, to power such components as a fuel delivery pump, an igniter and system control circuitry.
Cogeneration or Combined Heat and Power (CHP) systems are known that are arranged to simultaneously generate heat and electricity. For example, it is known for heat emitted by a power station as a by-product of electricity generation to be used in a local or district heating system. This use of waste heat serves to increase the efficiency of the plant and reduce negative impact on the *: environment. It is also known for boilers to generate electricity as a by-product of : producing heat.

For a better understanding of the invention and to show how the same may be carried into effect, there will now be described by way of example only, specific embodiments, methods and processes according to the present * : invention with reference to the accompanying drawings in which: Figure 1 shows a boiler unit comprising heat and electricity generating 25 apparatus; Figure 2 is a schematic view of heat and electricity generating apparatus and Figure 3 shows steps in an advantageous stage of heat transfer within of heat transfer within the operating process of heat and electricity generating apparatus according to the invention.
Detailed Description
There will now be described by way of example a specific mode contemplated by the inventor. In the following description numerous specific details are set forth in order to provide a thorough understanding. It will be apparent however, to one skilled in the art, that the present invention may be practiced without limitation to these specific details. In other instances, well-known methods and structures have not been described in detail so as not to
unnecessarily obscure the description.
Figure 1 A boiler unit 101 is shown in Figure 1, in a domestic environment 102. The boiler unit 101 is arranged to provide heat for transfer to a water flow, the heated water then being circulated through radiators of a central heating system or supplied to a water tank to provide hot water for consumer usage.
Advantageously, and as will be described in detail below, the boiler unit 101 comprises apparatus according to the present invention that is arranged to provide heat from high-pressure combustion and that is also arranged to generate electricity.
The provision of heat and electricity generating apparatus suitable for use in residential or small-scale buildings provides several benefits. The local production of electricity can replace electricity that would otherwise be drawn from the main electric power generation network (mains electricity grid). This serves to reduce consumer electricity usage charges, reduce maintenance costs : of the mains electricity grid, and contribute resource to the overall electricity generation capability of an area.
The high-pressure combustion performed by the heat and electricity generating apparatus provides further advantages. Combustion under high pressure is thermodynamically more efficient than combustion under atmospheric pressure, requiring less fuel to be used in the combustion reaction. In turn, this increased fuel efficiency leads to fuel costs savings and reduced emissions of environmental pollutants, in particular carbon dioxide (GO2) and mono-nitrogen oxides (generally referred to as NOR) that are contributors to global-warming.
Beneficially, and as will be described in detail below, the heat and electricity generating apparatus of the boiler unit 101 is arranged to provide an advantageous stage of heat transfer within the operating process.
Figure 2 Figure 2 is a schematic view of heat and electricity generating apparatus 201 according to the present invention, shown in a heating system 202 suitable fora residential building.
The heat and electricity generating apparatus 201 is arranged to provide heat from high-pressure combustion and also to generate electricity.
The heat and electricity generating apparatus 201 comprises a centrifugal air compressor 203, a turbo-expander 204 and an electric generator 205, which are operatively connected by a rotatable drive shaft 206. The heat and electricity generating apparatus 201 further comprises a high-pressure combustor 207, a first heat exchanger 205 and a second heat exchanger 209.
The centrifugal air compressor 203 has an inlet for admitting air from the atmosphere, and an outlet for issuing compressed air. The first heat exchanger 208 has a first conduit 210 and a second conduit 211. The outlet of the centrifugal air compressor 203 is in fluid communication with the first conduit 210 of the first heat exchanger 206.
The high-pressure combustor 207 has an inlet for admitting combustion air, a fuel port in fluid communication with a fuel source 212 for admitting a fuel, an igniter for igniting a fuel and combustion air mixture, and an outlet for issuing * 0 combustion product gas. Any suitable fuel may be used in the high-pressure combustor, such as natural gas, diesel or oil.
The first conduit 210 of the first heat exchanger 208 inlet is in fluid communication with the inlet of the high-pressure combustor 207. The turbo-expander 204 has an inlet for admitting gas and outlet for admitting expanded gas. The outlet of the high-pressure combustor 207 is in fluid communication with the inlet of the turbo-expander 204. The outlet of the turbo-expander 204 is in flUid communication with the second conduit 211 of the first heat exchanger 208.
The second heat exchanger 209 has a first conduit 213 and a second conduit 214. The second conduit 211 of the first heat exchanger 208 is in fluid communication with the first conduit 213 of the second heat exchanger 209. The second conduit 214 of the second heat exchanger 209 is arranged to receive a heat-conveying fluid: in heating system 202, the heat-conveying fluid is circulating fluid of a hot water system 215. The circulating fluid may be water, oil, helium or any other fluid of a hot water system or central heating system. The first conduit 213 of the second heat exchanger 209 is in fluid communication with an exhaust to atmosphere. The hot water system 215 is fluidly connected to a water tank 216 and/or central-heating system 217.
The electric generator 205 is electrically connected to interlace circuitry 218, which is electrically connected to a rechargeable electricity storage cell 219 and/or the mains electricity grid 220. The electric generator 205 is arranged to convert mechanical power generated by the rotation of the turbo-expander 204 into electrical power. The electric generator 205 is also preferably arranged to provide start-up power for initial operation of the heat and electricity generating process.
The rotatable drive shaft 206 is provided with bearings, indicated at 221, to facilitate smooth and balanced rotation. The rotatable drive shaft 206 may be provided with any of the following bearing types: hydrodynamic, air, magnetic, *r ball.
: 25 Advantageously, the heat and electricity generating apparatus 201 is * " arranged such that, in operation, combustion product gas received and subsequently issued by the turbo-expander 204 passes through the first heat exchanger 208, to heat compressed air issued by the centrifugal air compressor 203 prior to entry into the high-pressure combustor 207, and then passes through the second heat exchanger 209, to heat the fluid of the hot water system 215. In this way, the hot combustion product gas is firstly used to transfer heat to the combustion air prior to entry into the high-pressure combustor and then subsequently used to transfer to a heat-conveying fluid. Using the hot combustion product gas from the high-pressure combustor to pie-heat the combustion air increases the efficiency of the combustion. This leads to a reduction in the fuel used in the combustor and, in turn, a reduction in undesirable post-combustion emissions.
Features of an example will now be described. The centrifugal air compressor has a mass flow rate in the range 0.01-0.2 kg/s1 an outlet air temperature in the range 400-600 K, and an outlet air pressure in the range 2-6 bar. The inlet temperature of the first conduit of the first heat exchanger (receiving air from the centrifugal air compressor) is in the range 400-600 K, and the inlet temperature of the second conduit of the first heat exchanger (receiving combustion product gas from the turbo-expander) is in the range 800-900 K. The pressure loss within the first heat exchanger is approximately 6%. The outlet temperature of the first conduit of the first heat exchanger (issuing combustion inlet air to the high-pressure combustor) is in the range 450-800 K, and the outlet temperature of the second conduit of the first heat exchanger (issuing combustion product gas to the first conduit of the second heat exchanger) is in the range 550-700 K. The high-pressure combustor has a combustion air inlet temperature in the range 450-BOOK and a combustion product gas outlet temperature in the range 900-1300 K. The inlet temperature of the turbo-expander (receiving combustion product gas from the high-pressure combustor) is in the range 900-1300 K, the outlet temperature of the turbo-expander (issuing combustion product gas to the second conduit of the first heat exchanger) is in the range 800-900 K and the outlet pressure is in the range 10.5-1.5 bar. The inlet temperature of the first conduit of the second heat exchanger (receiving air from the centrifugal air compressor) is in the range 550-700 K, and the outlet temperature of the first conduit of the second heat exchanger (exhaust to atmosphere) is approximately 350 K. The rotational speed of the turbo-expander, centrifugal air compressor, rotatable drive shaft and electric generator is in the range 50,000-250,000 RPM. The first heat exchanger (combustion air pre-heater) transfers heat from the hot combustion product gas to the combustion air. The second heat exchanger (water system heater) transfers heat from the hot combustion product gas to water. The electric generator is electrically connected to an electric rectifier, and then to a grid interactive inverter (grid-tie inverter), to prepare the generated electricity for local use or supply to the mains electricity grid. The electrical generator can also generate power for electrically-powered elements of the system.
Figure 3 Figure 3 shows steps in an advantageous method of heat transfer 301 performed during operation of heat and electricity generating apparatus according to the invention.
At step 302, combustion product gas issued from a high-pressure combustor is passed through the turbo-expander. Combustion product gas issued from the turbo-expander is then passed through a first (air-to-air) heat exchanger, at step 302, to elevate the temperature of combustion air before entry into the high-pressure combustor. At step 303, combustion product gas issued from the first air-to-air heat exchanger is passed through a second (air-to-fluid) heat exchanger, to heat a heat-conveying fluid. This method of transferring heat using the hot combustion product gas improves the overall efficiency of the heat and electricity generating apparatus.
A boiler system comprising the heat and electricity generating apparatus described herein is suitable for use in a residential or small-scale building and provides several advantages, including reduced electricity bills and reduced harmful emissions. U *
