The invention discloses a waste heat boiler for preparing olefins from methanol, which can meet various steam use requirements in a system for producing the olefins by the methanol. The waste heat boiler comprises a heat insulation hearth which is vertically distributed, a secondary heat exchange channel which is vertically distributed, and a main heat exchange channel which is connected with the upper end of the heat insulation hearth and the lower end of the secondary heat exchange channel; a smoke inlet is arranged at the lower end of the heat insulation hearth and a smoke outlet is arranged at the lower end of the secondary heat exchange channel; a plurality of super-heaters are arranged in the main heat exchange channel; a plurality of groups of economizers are arranged in the secondary heat exchange channel from top to bottom; the heat insulation hearth is located on the side wall above the smoke inlet and provided with a heat booster for improving a smoke temperature in the heat insulation hearth. The waste heat boiler provided by the invention has the advantages that: after the heat booster is additionally arranged on the side wall of the heat insulation hearth, the temperature of high-temperature smoke in the heat insulation hearth is raised, therefore, the temperature and the steam quantity of steam which is generated through the super-heater can be improved. The generation requirement and the most of the steam use requirements of the technology in the system for producing the olefins by the methanol can be met.

The present invention relates to an urban energy supply system, in particular to a novel single-shaft natural gas combined cycle heat supply unit system, which includes a combustion chamber connected to a compressor connected to a generator I and a gas turbine connected to a waste heat boiler Connection, the waste heat boiler is connected with the thermal system of the condensing steam turbine and the thermal system of the back pressure machine, and the thermal system of the condensing steam turbine and the thermal system of the back pressure machine are respectively connected through the control system. The invention can realize safe and economical operation under two conditions of heating period and non-heating period, and the two operating modes are switched through the control system. In this way, on the basis of the original unit body that cannot be modified, the advantages of the back pressure unit are expanded to meet the heating demand during the heating period and meet the power generation requirements during the non-heating period. Using the back pressure machine for heating, the energy utilization rate is significantly improved, generally greater than 85%, and the operating efficiency is 25% higher than that of pure condensing.
