The SZS gas steam water-tube boiler adopts the design of the double-drum vertical D-type arrangement. The stress condition of the pressure body of the boiler is good. Important pressure components such as the drum are not directly radiated and washed by the high temperature flame. The pressure-bearing components can expand and contract freely, and the thermal stress is small, realizing a higher safety margin. Modular design of 20 ton gas boiler the boiler is divided into a body, an economizer and other accessories as a whole. The gas-fired steam boiler body is composed of a furnace and a single-circuit convection heating surface. The economizer is transported in a package to achieve the overall delivery and ensure the quality of the boiler.
The double-drum gas fired boiler is slightly positive pressure combustion, and the smoke and wind resistance is small. The steam boiler smoke and air system is only equipped with a blower. The furnace is in a slight positive pressure, which reduces the air leakage of the boiler and improves the efficiency of the boiler. Membrane water-cooling wall is used for safety precautions, which improves the rigidity of the furnace and flue, and improves the anti-explosion ability of the boiler furnace wall. Explosion-proof doors are set in the explosive parts to prevent the damage to the furnace wall by deflagration.
The 20 ton gas boiler is a typical high-efficiency energy-saving boiler. The boiler body adopts a “D” shape structure, one side is the furnace and the other side is the convection heating surface. The heating surface of the body reaches 271.50m2, and the radiation heating surface is sufficient. SZS series steam boiler combustion chamber adopts narrow-spaced tube-film water-cooling wall, which has better air tightness and thermal efficiency can be as high as 98% or more. The furnace has a large space, and with the low-nitrogen burner, it can easily achieve ultra-low emission requirements below 30mg/Nm3, and has excellent environmental performance.
This series of gas-fired boilers adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. It has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur when running in a slightly positive pressure state. This type of steam boiler is a self-contained boiler, which can shorten the installation period while meeting the requirements of transportation size. At the same time, the aluminum casing and the skeleton are transported and connected by bolts, which are convenient for disassembly and maintenance.
SZS series gas-fired boilers are designed with a super large combustion chamber, which makes the fuel burn completely, with high combustion efficiency and low pollution. The gas boiler has a surplus heating surface and a large enough space for soda and water to ensure the stability of the boiler parameters. There is an explosion-proof door on the top of the furnace, which can discharge the energy released by the explosion of the chamber.
The feed water of this type of boiler products adopts continuous electric adjustment, and has the functions of high and low water level alarm and interlock protection. The 20 ton gas boiler use water spray desuperheater, which has sensitive temperature adjustment and large temperature adjustment range. Considering the overall transportation requirements of the boiler, the design layout of the boiler is more compact. In addition, the boiler adopts a quick installation structure, which can effectively shorten the installation period.
