SZL series coal fired hot water boiler

SZL series coal fired hot water boiler Introduction

SZL series double pot tube vertical chain furnace drainpipe hot water boiler, adopt quick loading or assembly structure. 4~6t/h is quick water pipe structure, in the factory all complete and then leave the factory; 6~35t/h consists of two parts, the upper part is the heating surface and the lower part is the combustion equipment. The front end of the boiler body is composed of a combustion chamber connected by the upper part of the water wall arranged around the boiler with the boiler tube and the lower part connected with the header to absorb the radiant heat of the furnace, and the back end of the combustion chamber is arranged with a dense convection tube bundle between the upper and lower tubes. After burning, the high temperature flue gas passes through the secondary backhaul transverse scour to the convection heating surface, then leads to the separately arranged economizer, and finally enters The dust collector passes through the chimney.

Application fileds

Our oil/gas fired boilers can be divided into DHS series angle tube boiler,SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above. The fire tube boilers, on the contrary, are intended for use at pressures below 2.5 MPa. Fire tube boilers usually have a capacity of below 20t/h, while water tube ones of 20t/h or more as capacity expansion is possible.
The three series are designed with large furnaces, the thermal efficiency is over 98%, and the NOx emissions are as low as 30mg/Nm3. The front and rear smoke boxes are all equipped with a unique sealing structure to ensure that the smoke box does not leak smoke. At the same time, it has the characteristics of fully automatic and safe operation.
