Install Waste Heat Recovery Systems for Fuel-Fired Furnaces (English/Chinese) (Fact Sheet)

Description: Chinese translation of ITP fact sheet about installing Waste Heat Recovery Systems for Fuel-Fired Furnaces. For most fuel-fired heating equipment, a large amount of the heat supplied is wasted as exhaust or flue gases. In furnaces, air and fuel are mixed and burned to generate heat, some of which is transferred to the heating device and its load. When the heat transfer reaches its practical limit, the spent combustion gases are removed from the furnace via a flue or stack. At this point, these gases still hold considerable thermal energy. In many systems, this is the greatest single heat loss. The energy efficiency can often be increased by using waste heat gas recovery systems to capture and use some of the energy in the flue gas. For natural gas-based systems, the amount of heat contained in the flue gases as a percentage of the heat input in a heating system can be estimated by using Figure 1. Exhaust gas loss or waste heat depends on flue gas temperature and its mass flow, or in practical terms, excess air resulting from combustion air supply and air leakage into the furnace. The excess air can be estimated by measuring oxygen percentage in the flue gases.

Reduce Air Infiltration in Furnaces (English/Chinese) (Fact Sheet)

Description: Chinese translation of the Reduce Air Infiltration in Furnaces fact sheet. Provides suggestions on how to improve furnace energy efficiency. Fuel-fired furnaces discharge combustion products through a stack or a chimney. Hot furnace gases are less dense and more buoyant than ambient air, so they rise, creating a differential pressure between the top and the bottom of the furnace. This differential, known as thermal head, is the source of a natural draft or negative pressure in furnaces and boilers. A well-designed furnace (or boiler) is built to avoid air leakage into the furnace or leakage of flue gases from the furnace to the ambient. However, with time, most furnaces develop cracks or openings around doors, joints, and hearth seals. These openings (leaks) usually appear small compared with the overall dimensions of the furnace, so they are often ignored. The negative pressure created by the natural draft (or use of an induced-draft fan) in a furnace draws cold air through the openings (leaks) and into the furnace. The cold air becomes heated to the furnace exhaust gas temperature and then exits through the flue system, wasting valuable fuel. It might also cause excessive oxidation of metals or other materials in the furnaces. The heat loss due to cold air leakage resulting from the natural draft can be estimated if you know four major parameters: (1) The furnace or flue gas temperature; (2) The vertical distance H between the opening (leak) and the point where the exhaust gases leave the furnace and its flue system (if the leak is along a vertical surface, H will be an average value); (3) The area of the leak, in square inches; and (4) The amount of operating time the furnace spends at negative pressure. Secondary parameters that affect the amount of air leakage include these: ...

Using Waste Heat for External Processes (English/Chinese) (Fact Sheet)

Description: Chinese translation of the Using Waste Heat for External Processes fact sheet. Provides suggestions on how to use waste heat in industrial applications. The temperature of exhaust gases from fuel-fired industrial processes depends mainly on the process temperature and the waste heat recovery method. Figure 1 shows the heat lost in exhaust gases at various exhaust gas temperatures and percentages of excess air. Energy from gases exhausted from higher temperature processes (primary processes) can be recovered and used for lower temperature processes (secondary processes). One example is to generate steam using waste heat boilers for the fluid heaters used in petroleum crude processing. In addition, many companies install heat exchangers on the exhaust stacks of furnaces and ovens to produce hot water or to generate hot air for space heating.

Examining Help-Seeking Intentions of Chinese Individuals: A Path Analysis

Description: Utilizing the theory of planned behavior, I examined the variables that affect Chinese individuals' help-seeking intention. A total of 251 Chinese individuals participated in this study. Results showed that the variables in the theory of planned behavior accounted for 16% of the variance in help-seeking intention. Specifically, attitude (r = .22, p < .001) and perceived behavioral control (r = .22, p < .001) were found to be significant predictors of help-seeking intention. Based on these results, mental health professionals can design outreach interventions, such as psychoeducational programs, to improve Chinese individuals' help-seeking attitude and perceived behavioral control in an attempt to increase mental health service utilization. Additionally, counselors can discuss with clients' their attitude and perceived behavioral control regarding seeking counseling in an attempt to assist clients in being committed to the counseling process.

Eastern Work Ethic: Structural Validity, Measurement Invariance, and Generational Differences

Description: This present study examined the structural validity of a Chinese version of Multidimensional Work Ethic Profile (MWEP-C), using a large sample of Chinese parents and their young adult children (N = 1047). Confirmatory factor analysis (CFA) was applied to evaluate the model fit of sample data on three competing models using two randomly split stratified subsamples. Measurement invariance for these two generational respondents was checked using differential item functioning (DIF) analysis. The results indicated that MWEP-C provided a reasonable fit for the sample data and the majority of survey items produced similar item-level responses for individuals that do not differ on the attributes of work ethic across these two generations. DIF items were detected based on advanced and successive iterations. Monte Carlo simulations were also conducted for creating threshold values and for chi-square probabilities based on 1,000 replications. After identifying the DIF items, model fit improved and generational differences and similarities in work ethic between parents and their young adult children were also identified. The results suggested that the younger Chinese generations have higher work ethic mean scores on the dimensions of work centrality and morality/ethics while they have similarities on time concept, self-reliance, delay of gratification, and hard work as their parents.

Filial Therapy with Immigrant Chinese Parents in Canada

Description: This study was designed to determine the effectiveness of filial therapy training in: (a) increasing immigrant Chinese parents' empathic behavior with their children; (b) increasing immigrant Chinese parents' acceptance level toward their children; (c) reducing immigrant Chinese parents' stress related to parenting; (d) reducing immigrant Chinese parents' perceived number of problem behaviors in their children; and (e) enhancing the self concept of the Chinese children of immigrant Chinese parents.

Do Non-Native Grammars Allow Verbs to Raise to Agreement?

Description: The purpose of this thesis is to determine whether the setting of the verb movement parameter in L2 is dependent on agreement acquisition. The Optionality hypothesis (Eubank, 1994) is tested by examining the L2 grammar of Chinese learners of English. To test this hypothesis, the sentence matching procedure originally described in Freedman and Forster (1985) is used. It is found that no current theory truly accounts for the results that are obtained.
