Gas Heating

In the Southern Region of our Country (Argentina), pipeline natural gas is heated up to suitable temperatures by combustion of natural gas in indirect type heating systems. In one of the points in which such heating is necessary, the pipeline that transports about 14 million standard cubic meters per day of natural gas at 45 bar of pressure and whose temperature is wanted to rise from −2°C to 30°C, is placed about 500 m away from of a regional thermoelectric power station. It has 3 7 MW gas turbines, exhausting 25.8 kg/s of combustion gases at 510°C each. A preliminary calculation showed that the waste heat of one of them can closely supply the necessary duty for gas heating. In this work, a preliminary analysis and economics of the system are described.

PurposeThe aim of the present study is to assess the selected heating systems (furnace and boiler) commonly used in the dwellings of seven post-USSR (the Union of Soviet Socialist Republics) countries. The systems were assessed in terms of their cost and environmental performance, with natural gas and electricity used as the main source of energy.Design/methodology/approachThe cost-effectiveness and environmental performance of the selected heating systems that have been commonly used in the selected post-USSR countries was assessed. Current energy (natural gas and electricity) prices that are applied in those countries were used.FindingsResults show that the furnace is the cheapest option, while natural gas is the cheapest source of energy, despite its high price in Tajikistan and Kyrgyzstan. Both heating systems could be considered eco-friendly options, although their efficiencies need to be considered at the design stage. Turkmenistan, Uzbekistan and Kazakhstan, which are the top natural gas producers, offer natural gas for the selected heating systems as both cost-effective and eco-friendly options.Practical implicationsA considerable reduction in electricity consumption and less harm to our environment can be achieved through the systems used in residential buildings in the region.Originality/valueThe outcomes of the present study offer value (in terms of cost-effective and eco-friendly options) for the end-users in the region.

Reduce Energy Consumption

Soil contamination remains a global problem. Among the different kinds of remediation technologies, in situ soil thermal remediation has attracted great attention in the environmental field, representing a potential remedial alternative for contaminated soils. Soils need to be heated to a high temperature in thermal remediation, which requires a large amount of energy. For the natural gas heating system in thermal remediation, a fuzzy coordination control strategy and thermohydraulic dynamics model have been proposed in this paper. In order to demonstrate the superiority of the strategy, the other three traditional control strategies are introduced. Analysis of the temperature rise and energy consumption of soils under different control strategies were conducted. The results showed that the energy consumption of fuzzy coordination control strategy is reduced by 33.9% compared to that of the traditional control strategy I, constant natural gas flow and excess air ratio. Further, compared to the traditional control strategy II, constant excess air ratio and desired outlet temperature of wells, the strategy proposed can reduce energy consumption by 48.7%. The results illustrate the superiority of the fuzzy coordination control strategy, and the strategy can greatly reduce energy consumption, thereby reducing the cost of in situ soil thermal remediation.

Taking three cities in China — Shanghai, Beijing and Chengdu — as examples, under different power price and natural gas price policies, and at the same output level, this paper compares Building Cooling Heating and Power system (BCHP) with the other four cooling/heating sources systems by economic analysis. This paper calculates Life Cycle Cost (LCC) of the five systems to determine which the best is and which the worst is. The author compares the LCC of power-driven cooling/heating systems with that of gas-driven systems especially when power users should pay the basic electricity cost according to the maximum power demand (MPD) or transformer capacity. This paper defines price ratio of electric power to natural gas, builds first-order linear regression equation of equivalent uniform annual cost (EUAC) ratio of BCHP to power-driven air source heat pump to calculate the feasible price ratio of electric power to natural gas. Accordingly, the author suggests that government should give preferential natural gas price subsidies policies to BCHP users.
