what effected high alkalinity in steam boiler

INTRODUCTION

WNS series gas / oil fired hot water boiler adopts advanced structure, the boiler structure is compact, occupies a small area, installs quickly. The boiler adopts advanced mechatronics automatic control technology, high quality silicic acid encryption and insulation, reduce heat loss. Horizontal industrial boiler composes furnace body, access door hole, front and rear smoke chamber, insulation layer cover, burner interface, pipes, valves and instruments, platform and stairs, instruments and safety devices, supporting accessories, electrical control cabinet.
