Simulation of Combustion and Alkali Metal Distribution in Zhundong High Alkali Coal Boiler Based on Computer Control System

Restricted by Xinjiang’s special geographical location, economic conditions, transportation and other factors, Zhundong coal can’t be sent out on a large scale, which seriously hinders the development of Zhundong coal base. Meanwhile, due to the coal-forming history and Xinjiang’s special natural geographical environment, the alkali metal content in Zhundong coal is generally over 2%, which is much higher than that of power coal in other parts of China. In this paper, based on computer control system, the combustion and alkali metal distribution in Zhundong high alkali coal boiler are simulated, and the morphological distribution characteristics and migration laws of alkali metals such as Na and K in pulverized coal combustion process of high alkali coal, low alkali coal and their two coal samples are deeply studied. Combustion characteristics and heat flow distribution, the simulation results show that the flue gas temperature at the furnace outlet is 895.07°C, and the flue gas temperature near the wall is low, which is helpful to alleviate the slagging and contamination in the furnace.

Modeling of information interconnection in a computer control system of moving objects

The subject of research is a pool of widgets, which provides a user interface in a computer control system for moving objects. The object of research is the process of information exchange between the components of a computer system, which are directly involved in the control of moving objects. The task of allocating resources for a pool of widgets that provide operational control of moving objects is critical. As the number of elements increases in the pool of widgets, the competition for the resources of the computer system increases significantly, respectively, the queues for the most demanded resources grow. Therefore, it is necessary to reallocate resources between requests in such a way that the priorities of requests are taken into account, and the response time of operational requests does not exceed the standard time. Such distribution cannot be realized without a model that would show the parameters of all information flows between the components, which is the purpose of this article. In doing so, the model must consider the characteristics of the pool of widgets that support the user interface. Research results. To achieve this goal, several particular tasks were solved. First, the main sets were identified that will be involved in modeling information interconnections between software components that service requests for user interface widgets in a computer system environment. Then, a diagram of informational interconnections between these sets was developed. Further, the parameters of the requests, which were initiated by the widgets, of the applications, and the fragments of the widget query service database were determined and formalized. All this made it possible to form a model of information interconnections using a tuple of obtained vectors, sets, and Boolean matrices. In the proposed mathematical model, many limitations are imposed on the elements of this tuple, associated with the characteristic features of the control module for the user interface of the computer system. Besides, the limitations associated with the functioning of the basic network of the computer system are taken into account. In the final model, Boolean matrices affecting resource allocation defined as model variables. A fast algorithm for determining the space of admissible distributions is proposed. Conclusions. The developed mathematical model determines the parameters of information flows between the components of the computer system, which are involved in the control of moving objects. This model will allow for the operational reallocation of resources between requests using the proposed fast algorithm.

Properties of Alumina Coatings Deposited by Detonation Spraying

Coatings deposited by detonation spraying equipment CCDS2000 using alumina powder are studied. CCDS2000 is characterized by a computer control system, robot compatible spraying unit (gun barrel), a portable chiller, two powder feeders, and other peculiar properties. This installation allows to deposit coatings on complex shape surfaces and thin-walled parts under optimal conditions. Studies of the coating properties included measurements of coating microstructure, porosity, microhardness, adhesion, cohesion, abrasive and erosive wear, and dielectric properties (specific resistivity and dielectric strength). The detonation sprayed coatings have an adhesion of 60-70 MPa, cohesion of 100 MPa, microhardness of 1500 HV100, porosity of about 1% (measured on microsections of coatings using OLYMPUS Stream Image Analysis software). Impregnation of coatings with silicone oil showed that the real open porosity of coatings is up to 6%. Dielectric strength of the ceramic layer with the thickness of 200 μm exceeds 30 kV/mm. Specific resistivity depends on atmospheric humidity and when the relative humidity is less than 60%, the specific resistivity is greater than 1013 Ω·cm.
