TECHNOLOGY AND EQUIPMENT FOR FLUE GASES HEAT RECOVERY OF GAS-CONSUMING BOILERS.

Scope – heating boiler and industrial heating boilers

The goal – improving fuel efficiency.

The technology provides two options for the application: the first one – hot water heating systems, hot water supply and other needs, the second one – heating and humidification of combustion air in boilers. In both cases, the deep gas cooling is realized – up to below the dew point temperature, followed by drying (heating) of gases before entering the chimney. (Patent number 30551A Ukraine, № 45766A, № 56591A).

The advantages over existing technologies are the next:

• The use of the latent heat of condensation of water vapor contained in the flue gases. Heat recovery equipment, small-sized, easy to use and maintain.
• The increasing of fuel available heat factor (boiler efficiency) is 7-10%. Aerodynamic resistance is 150-300 Pa. The nominal thermal performance of heat recovery depends on a heat output of the boiler.
• The payback period for heat recovery equipment introduction is 1.5-2 years.
• The emissions reduction from gas-fuel combustion is – 7-10%. For the option of combustion with air humidification provides additional environmental benefits – the concentration of nitrogen oxides in the exhaust gases is reduced by 40-50%.
• The technology allows more closely match the needs of the population in the heat and reduce tariffs for heat energy.
• The introduction of corresponding equipment term is 3 – 6 months, depending on the effort of the contract.

THE TECHNOLOGY AND EQUIPMENT FOR FLUE GAS HEAT RECOVERY

IN GAS-CONSUMING FURNACES.

Scope – the gas-consuming furnaces (glass melting, kilns, etc.) of various industries.

The goal – improving fuel efficiency.

The technology provides two options for the application: the first one – waste heat recovery from flue gases for water heating system and hot water supply, the second one – the use of flue gases waste heat to preheat air entering the regenerator (heat exchangers) of the furnace for combustion. In the first case, hot-water boilers of panel and gas pipe types are used. The second option uses air heating heat exchangers. In heating water and gas pipe heat exchangers flow turbulators are used. The design of proposed heat exchanger provides for cleaning possibility of heating surfaces from dust deposits.

The main branches of the introduction are glass industry, building materials industry, engineering industry. Proposed technology has been implemented on 11 enterprises in Ukraine and – on 2 in the Russian Federation.

The advantages of proposed heat exchanger design in comparison with existing solutions are:

• The ability of cleaning the heat transfer surfaces from the technology entrainment sediment as well as the use of heat exchange tubes with circular baffles, which allow get a heat transfer intensification and decreasing a steel intensity of the equipment by 1.5-2 times.
• The increasing of fuel utilization by 15-30%, total air resistance is 500-700 Pa. The nominal thermal performance of heat recovery depends on a heat output of the boiler.
• The payback period for proposed equipment introduction is 0.5-1 years.
• The reduction of harmful emissions from the fuel combustion – by 15-30%.
• The technology reduces the cost of production, thus creating conditions for the redistribution of income in favor of the owners and employees of industrial enterprises, as well as improves heat supply reliability of these enterprises.
• The introduction of corresponding equipment term is 0.5 to 1 year, depending on the effort of the contract.

 

COGENERATION TECHNOLOGIES AND EQUIPMENT FOR THE GAS ENGINE GENERATORS.

Scope – a small thermal power plant.

The goal – improving fuel efficiency, costs reduction for the power and heat energy purchasing.

The technology provides a combined process of simultaneous production of heat and power in a single device, called the cogeneration plant, based on gas engine generators. In this technique the production of thermal energy in the form of hot water is provided by external waste heat utilization of motor generators in respective heat exchangers, including heat for combustion (in the gas-water heat exchanger). The heated water is used for hot water supply.

The main branches of the equipment introduction are a wide range of businesses that have a need for power and heat energy. The company where is carried out the introduction – Gostomelsky Glass Factory (Kiev region).

The advantages over existing technologies are:

• The uses for gas-water heat exchanger special profiled tubes (tubes with circular vortex generators) which allow get heat transfer intensification and decreasing a steel intensity of the equipment by 1.5-2 times.
• Increasing the fuel utilization factor by 15-20%. The nominal heating cogeneration of the unit is determined by the enterprises needs in thermal and power energy.
• The payback period is 2-5 years.
• The reduction of harmful emissions from the fuel combustion is 15-20%.
• The technology allows more closely matching the needs of enterprises in power and heat energy, reducing the rates for these types of energy.
• The introduction of corresponding equipment term is 0.5 to 1 year, depending on the effort of the contract.
