5.　Boilers

5.1　General

The number of production of boilers for marine use has been gradually increased since 1995, and 475 boilers were produced in 1997, which was about 123% compared with that in 1996.

In the technological aspect, researches and developments have been advanced in miniaturization of the boiler combustion chamber, energy saving, exclusive and mixed combustion of gas/heavy oil including the gas fired auxiliary boiler, and countermeasures for the air pollution by NOx, SOx, etc., and examination on the monitoring system of the auxiliary boiler/exhaust gas economizer.

　

5.2　Number of Production

Fig. 5.1 and Fig. 5.2 show the production of boilers for marine use during 10 years since 1988 which are summarized in "Statistics of Products in Marine Industry" by the Ministry of Transport.

Fig. 5.1 shows the number of production of boilers by the kind, and the number has been on the same trend for these several years.

5.3　Major Trend

5.3.1　Main Boiler

Two sets of main boilers 17T/H and 2 sets of boilers of 68T/H for LNG carriers were manufactured by MHI, 4 sets of boilers of 54 T/H were manufactured by MES, and 2 sets of boilers of 68T/H were manufactured by KHI, and total 10 boilers were delivered. MHI received orders of 2 sets of 21 T/H boilers, 2 sets of 44 T/H boilers, 8 sets of 68 T/H boilers, KHI received orders of 10 sets of 68 T/H boilers, and totaling 22 boilers. Boilers for LNG carriers are delivered to Korean shipbuilders and Qatar Project.

Demands on the main boilers for LNG carriers will be expected.

　

5.3.2　Auxiliary Boiler

Two hundred and seventeen sets of auxiliary boilers were manufactured in 1997, and 170 sets of composite boilers were manufactured. Fig. 5.3 shows the number of production and the orders received of main and auxiliary boilers by 8 boiler manufacturers in 1997 with reference to the boiler capacity. On the whole, both the number of production and the orders received are on the increase, and the orders received of auxiliary boilers of medium to large capacity was increased by about 155% compared with those in 1996 supported by the demands on tankers are increased.

Fig. 5.4 shows the summary of the number of production and orders received of the composite boilers, and the number of production and orders received of the composite boilers of 1-2 T/H class are increased by about 110% compared with those in 1996 on the whole.
