Introduction

> Superheated Water Steam Boiler
Water Tube Boiler | Double Drums Water Membrane Wall Boiler | Fuel: Gas Diesel Heavy Oil / Coal Wood Biomass
> Oil Gas Type Superheated Boiler
※ SZS Water Tube Superheated Boiler, Use gas, diesel, heavy oil, lpg, dual fuel. Capacity in 2ton-100ton.
※ SZS gas & oil water tube boiler is arranged as drum longitudinal type “D” shape, it’s quickly assembled boiler with water tube, has the characteristics of high steam quality, sufficient output, high thermal efficiency, etc.
※ The structure of furnace water cooling wall and convection gas pass is membrane wall, have good sealability, and effectively reduce refractory brick quantity and maintenance workload.
※ The layout of economizer at boiler tail could effectively reduces exhaust gas temperature and improve boiler thermal efficiency.
※ This series gas fired water tube boiler is delivered as whole when leave factory, convenient for transportation, and has a short install period.
> Coal Biomass Type Superheated Boiler
※ SZL/SZW series Water Tube Superheated Boiler, suitable for capacity demand in 2ton-50ton, 1.4mw-35mw.
※ Fuel: Coal, Charcoal, Wood biomass pellets, Woodchips, Palm kernel shells, Ricehusk, Peanut shells, Coconut Shells, etc.
※ It is double-drums water tube assembly chain grate boiler (A/D type). High technology, environmental and energy-saving. Large heating surface, make sure enough space for biomass burning, automatic fuel feeding and slag removing system.
Technical Design

Larger Comubustion furnace
Enough big combusition space, gas/oil burning sufficiently. Quick running, strong power to steam generating with 10minutes.
Membrane type water wall structure
Whole membrane type water wall structure is adopted around the furnace, has good sealing performance, low heat loss, no smoke and smoke leakage.
Higher quality steam generation
Compared with fire tube boiler, szs water tube boiler generating higher quality steam for using. (Moisture content<3%)
Saturated Steam & Superheated Steam
SZS series boiler can generate superheated steam for higher temperature compared with fire tube boiler, to reach different processing demand.Technical Parameter
