Computation of metal temperatures in a furnace waterwall of a boiler is necessary for the
proper selection of tube material and thickness. An adequate knowledge of the heat flux …

A heat flux entering steam generating tubes in power station boilers may be a critical factor
in considering the safety of the tubes. The knowledge of the distribution and magnitude of …

The main aim of this paper is to estimate the lifetime of water walls of pulverized-coal boilers
at nominal conditions as well as after degradation of water tubes. An approach for a …

In this paper, a method for determining fireside heat flux, heat transfer coefficient on the
inner surface and temperature of water-steam mixture in water-wall tubes is developed. The …

Three different tubular type instruments (flux tubes) were developed to identify steady-state
boundary conditions in water wall tubes of steam boilers. The first meter is constructed from …

Existing algorithms with iterations as the principle for 3D inverse heat conduction problems
(IHCPs) are usually time-consuming and resource-demanding. With the recent …

To achieve a precise assessment on thermal performance of a D-type water-cooled natural
gas-fired boiler the present paper was aimed at determining temperature distribution of …

In this paper, the heat transfer in 4-pass 500HP fire-tube steam boiler is numerically
investigated. A calculation program is carried out in order to simulate the heat transfer …

A single tube model based on the finite volume method and measured temperature of inlet
and outlet steam is proposed to evaluate the wall temperature profiles of the high …

Based on the linear superposition theorem a procedure is proposed for determining steady
heat fluxes on boundaries which pose an inverse conduction problem. Error analysis …
