Output variability with L.P.G.
5.08 Heat output variability characteristics
To adjust furnace heat input, simply regulate the main burner via the gas valve (fig. 8). This in turn
varies the heat output to the C.H. water. The diagrams in Fig. 9a and 9b show the variations in heat
output to the water in relation to variations in burner working pressure. The ability to adjust boiler
output to actual C.H. requirements means above all reducing heat dispersion and so saving fuel. In
addition, variations in output have very little effect on efficiency and combustion characteristics.
