Periodical : Teploenerg., 9, 51-54, S 1955
Abstract : Authors report on experiments made with the distil-
lation of liquid fuel and the calculation of vola-
tility, liquid -vapor mixture) viscosity, etc. The
theory of using the centrifugal atomizer, as expounded
by G. N. Abramovich and I. I. Novikov, and the formula
forthedimension of drops are presented. The testing
installat ion is discussed in detail and a curve
presents the,fractional distillation of the liquid
fuel. A mathematical analysis of the unstable
fluctuations and the viscocity of the flow is
presented. Three diagrams. Five Russian references,
1931-1955, 1 aerman, 1931.

TITLE: A generalisation of recent American investigations into
heat exchange in boiler furnaces. (Obobshcheniye

pp.18 - 24 (U.S.S.R .)
ABSTRACT: In recent years in the U.S.A. the Bureau of Mines
and the American Society of Mechanical Engineers (ASME)
have carried out important investigations on heat
exchange in the furnaces of modern steam boilers. The
heat output has been evaluated both on the basis of the
thermal balance of the boiler and on the heat absorption
of the screens calculated from measurements of the
temperature drop at the walls of the screen tubes. The
value of the information consists in that a detailed
investigation of temperature fields and gas composition
was made at the outlet section of the furnaces. A defect
of the work is 'that in most cases there is no data on
the speed distribution in the sections examined. There-
fore, the experimenters base their calculation on the
assumption of a constant rate of gas flow over the entire
section. In experiments with pulverised fuel and gas
firing this assumption appears to be justified because
of the satisfactory agreement between calculations of
hpLtl _abaorption based on the thermal balance and the

results of measurements of temperature drop at the walls
of the screen tube. The agreement was much less
satisfactory in the case of burner-bed furnaces, in
which, presumably, the velocity distribution in the
outlet section of the furnace chamber is far from
uniform. The results obtained at the Tidd, Paddy's
run, Willow Island, Sterlington and Whiting stations
are briefly,described. A committee of ASME compared the
experimental data with the methods used in the U.S.A. to
calculate heat exchange in boilers. However, the
American authors do not develop their work in such a
way that it is possible to tell the accuracy with which
the method of calculating heat exchange in furnaces
used in the U.S.S.R. reflects the experimental-results
obtained in the U.S.A. and most of the present article
is devoted to elucidation of this question by working
up the American data. An expression is first given for
the contamination factor and values are tabulated'for
the following cases: operation without soot blowing of
screened surfaces; operation with clean screens and-six
hours after blowing; and for operation without soot
blowing. American data is also presented in the form of
graphs, on which results obtained by the Soviet standard
method are also plotted. It is concluded that the data

on heat exchange in furnaces obtained in the experiments
at the Tidd, Paddy's run and Sterlington stations are in
good agreement with calculations made in accordance with
the recommendations of the Standard method of making
thermal calculations on boiler sets. Data on heat
exchange in the furnace of the Willow Island station
were obtained under abnormal operating conditions with
heavy slagging of the screens and cannot be considered
characteristic for modern boiler sets. The data on the
furnace of the Whiting station are insufficiently
accurate and their deviation from the calculated values
corresponds to an error associated with inaccuracies in
the evaluation of the gas temperature at the outlet from
the furnace and of the excess air. The experiments at
the Tidd station are characteristic of clean heating
surface of pulverised fuel furnaces immediately after
careful soot blowing to which corresponds a contamination
factor of 0.8. For calculation of heat exchange in
furnaces in which the screens are effectively cleaned
each shift, a mean contamination factor of 0-75 is
recommended. The experiments confirm the numerical values
for the coefficients used in the formula for the
contamination factor given in the standard method.

heat exchange in boiler furnaces. (Cont.)
The experiments at the Paddy's run station permit
evaluation, for furnaces with frontal burners, of the
influenceof the temperature of gases leaving the
furnace, the configuration of the torch and the
introduction of an upper row of burners. In other words,
there is no need to make special allowance for these
special features of the furnace conditions in formulae
for the calculation of heat exchange in furnaces. The
experiments at the Sterlington station confirm the
possibility of calculating the radiation of a natural
gas flame from data for radiation of non-luminous flames.
